Achromatic Nikon Ph3 DL 40x / 0.55 LWD microscope objective for brightfield and phase contrast, with 0 - 2.0 mm correction collar, for 160 mm tube length - for inverted and upright biological microscopes, made in Japan.

Basic objective parameters:
Manufacturer: Nikon, Japan
Model: Ph3 40 DL 0.55 LWD 160/0-2
Magnification: 40x
Numerical aperture (N.A.): 0.55
Optical correction: achromat
Phase contrast: Ph3 DL - Ph3 indicates the size of the phase ring (requires a matching Ph3 annulus in the condenser), DL (Dark Low) means dark, i.e. positive phase contrast - the object appears darker than the background
Working distance (WD): ~2.1 - 2.5 mm - LWD (Long Working Distance)
Correction collar: compensates for cover glass or vessel bottom thickness in the range 0 - 2.0 mm
Cover glass: the objective can be used without a cover glass, with a standard cover glass approx. 0.17 mm thick, and also with specimens observed through the bottom of a Petri dish up to 2.0 mm thick
Immersion: no (dry objective)
Tube length: 160 mm
Parfocal length: 45 mm
Thread: RMS
Optics: CF (Nikon CF-160) - requires no compensating eyepiece and allows photography by direct projection

This objective is suitable for:
- inverted microscopes - observation through the bottom of a Petri dish or cell culture flask
- upright biological microscopes - observation of specimens with or without a cover glass

Phase contrast work requires a compatible phase contrast condenser or a slider with a phase contrast annulus.

Commonly used, inexpensive cover glasses are 0.17 mm thick mainly in theory. Even the standard for class #1.5 allows a range of 0.16 - 0.19 mm, and in cheap Chinese cover glasses you will find in practice pieces from approx. 0.13 to 0.25 mm, often not matching the thickness stated on the box. Only #1.5H (high precision) cover glasses have a guaranteed thickness of 0.170 mm with a tolerance of +/- 0.005 mm. Variation in cover glass thickness clearly degrades image contrast and resolution (spherical aberration). The correction collar fitted to the objective offered here lets you adjust the optics to the combined thickness of the cover glass and the medium layer beneath it. This compensates for most of the variation found in practice.

In addition, the correction collar of this objective can be set to "0" for work without a cover glass, or to large values (up to 2.0 mm) to adapt the optics to observation through a microscope slide (0.8 - 1.2 mm), a glass Petri dish (usually 1.5 - 2.0 mm - thicker dishes are outside the collar range) or a plastic Petri dish (usually approx. 1 mm, in the range 0.8 - 1.2 mm).

This objective fits practically any microscope from any manufacturer, provided it has an RMS thread and uses objectives for 160 mm tube length with a parfocal length of 33, 37 or 45 mm. Some example microscopes are listed in the "compatibility" section, but the list is not complete.

What is this part needed for?

• if your microscope is missing a 40x objective - for brightfield or phase contrast
• if you observe cell cultures, algae, protozoa or fungi in Petri dishes on an inverted microscope
• if a standard 40x objective cannot focus through the thick bottom of a Petri dish or culture flask, or touches the vessel
• if you want to observe living, unstained specimens in phase contrast
• if you need an objective with correction for cover glass or vessel bottom thickness
• if you work with specimens without a cover glass
• if you want to photograph specimens by direct projection
• if you already have such an objective, but it is damaged or of very poor quality

This is description of this part:

Wild Heerbrugg 20x microscope objective from the Wild M20 microscope

Manufacturer: Wild Heerbrugg, Switzerland
Model: Fluotar 20 0.60
Magnification: 20x
Correction: Fluotar (other names: Fluor and fluorite)
Numerical aperture N.A.: 0.60
Tube length: 160 mm
Parfocal length: 33 mm
Cover glass: yes, 0.17 mm thick
Immersion: no (dry objective)
Thread: RMS

The objective comes in its original protective case marked "Wild Heerbrugg Switzerland".

Fluotar is the name Wild Heerbrugg used for its fluorite objectives, i.e. semi-apochromats - their lenses contain fluorite or glass with similar optical properties. A standard achromat corrects chromatic errors for only two colors (red and blue), so colored fringes may appear along the edges of objects. An apochromat corrects for three colors (red, green and blue) and represents the highest class of correction. The Fluotar sits between them - colored fringes are clearly smaller than with an achromat, although the correction is not as complete as with an apochromat. Fluorite also transmits ultraviolet light well, which is why objectives of this type were used in fluorescence microscopy.

This is a so-called "short barrel" objective with a parfocal length of 33 mm. It is very common to mount this objective on a 12 mm extension, which allows it to be used in microscopes that require 45 mm parfocal objectives. Professional adapters with protective optics, metal adapters and popular DIY 3D-printed adapters all work well for this.

This objective fits practically any microscope from any manufacturer, as long as it has an RMS thread and accepts objectives with TL=160 mm and a parfocal length of 33 mm (or 37 / 45 mm with a suitable adapter). Several example microscopes are listed in the "compatibility" section, but the list is not complete.

What is this part needed for?

• If you have a Wild Heerbrugg microscope without objectives and want to complete it with original parts
• If your microscope lacks an objective of this magnification and you want to add one
• If you have an objective of this magnification, but it is an achromat - and you want a visibly better image
• If you have such an objective, but it is of very poor quality or damaged
• If you like to be prepared and want to keep such an objective as a spare
• If you want to use this objective on other compatible microscopes

Achromatic 10x microscope objective by Steindorff Berlin.

Manufacturer: Steindorff Berlin
Model: 10/0.30
Magnification: 10x
Correction: achromatic
Numerical aperture N.A.: 0.30
Tube length: 170 mm
Parfocal length: 37 mm
Cover glass: yes, 0.17 mm thick
Immersion: no (dry objective)
Thread: RMS

The Steindorff 10x objective is also suitable for macro photography, as it does not require a cover glass and allows direct projection onto the camera sensor without intermediate optics.

This is a so-called "short objective", with a parfocal length of 37 mm. It is particularly common to mount this objective on an 8 mm extension, which makes it possible to use the objective in microscopes requiring objectives with a parfocal length of 45 mm. Both professional adapters with protective optics and metal adapters, as well as popular DIY solutions made with a 3D printer, work well for this purpose.

Like a large proportion of microscope objectives manufactured in Germany in the 1960s and 1970s, this objective has a parfocal length of 37 mm and a tube length of 170 mm. This means that it is often used as a replacement objective for other German microscopes, such as:
- Leitz Wetzlar
- Kremp Wetzlar
- Hertel & Reuss
- Steinmar Berlin
- CBS Beck Kassel
- ROW Rathenow

This objective fits practically any microscope from any manufacturer, provided that it has an RMS thread and supports objectives designed for TL = 170 mm and with a parfocal length of 33 / 37 mm (or 45 mm when using a suitable adapter). Several examples of such microscopes are listed in the "compatibility" section, but this is not a complete list.

What is this part needed for?

• if you have a Steindorff Berlin microscope and are missing exactly this type of objective to complete it
• if you already have such an objective in your microscope but it is of very poor quality or is damaged
• if you want to have such an objective as a spare
• if you want to use this objective with another compatible microscope
• if you want to use this objective for macro photography with a 10:1 reproduction ratio

This is description of this part:

LOMO (ЛОМО) microscope objective with low 8x magnification, made in 1991.

The LOMO 8x objective (model 8 0.20) is frequently used for macro photography with a microscope or a camera (via an RMS adapter or a bellows). Although it is an achromat, it renders fine detail very sharply and performs well in focus stacking. It complements a set together with the LOMO 3.7x, Carl Zeiss Jena Semiplan 6.3x and Nikon M Plan 10x.

Basic parameters of this objective:
Manufacturer: Lomo, Russia (ЛОМО)
Magnification: 8x
Correction: achromatic
Marking on the objective: 8 0.20
Numerical aperture N.A.: 0.20
Serial number: starts with "91"
Year of manufacture: 1991
Tube length: 160 mm
Parfocal length: 33 mm - so-called short barrel objective
Cover glass: not critical - objectives with such low magnification work both with and without a cover glass
Immersion: no (dry objective)
Thread: RMS

Important - this objective is suitable for direct projection photography, as it does not require plan-compensating optics.

A microscope objective with such low magnification (with a 160 mm tube length it gives an 8:1 reproduction ratio) is used, among other things, for observing or photographing:
- insects
- minerals
- inclusions in amber
- handwriting
- micro shells (micromollusks)
- and much more

Why do I state the year of manufacture in the description of this objective? Older LOMO microscope parts (objectives, microscopes, heads) have the year of manufacture encoded in the serial number: the first two digits of the serial number are the year. Many users want to complete their microscope with parts made in the same year as the microscope itself.

This is a so-called short barrel objective with a parfocal length of 33 mm. It is very often mounted on a 12 mm extension, which allows it to be used in microscopes that require objectives with a 45 mm parfocal length. Professional adapters with protective optics, metal adapters and popular DIY 3D-printed adapters all work well here.

Fun fact: LOMO made adapters between the RMS and M27 threads. Thanks to them, this objective was fitted to the Lomo Biolam I and Lomo Biolam M microscopes. Owners of Carl Zeiss Axio series microscopes with M27 thread also took advantage of this and used these adapters.

LOMO objectives are very popular with owners of microscopes from other manufacturers. Due to historical ties, owners of Carl Zeiss Jena microscopes regard them as an obvious replacement for the German objectives.

This objective fits practically any microscope from any manufacturer, as long as it has an RMS thread and accepts objectives with TL = 160 mm and 33 mm parfocal length (or 37 / 45 mm with a suitable adapter). Several example microscopes are listed in the "compatibility" section, but the list is not complete.

What is this part needed for?

• If you want to complete your Lomo microscope with original parts
• If you are looking for an objective for macro photography
• If you are looking for a low-magnification objective for observing objects with external, side-mounted incident light
• If you need an 8x objective for Lomo, Carl Zeiss Jena or other compatible microscopes
• If you have a Lomo microscope from 1991 (serial number starting with "91") and want period-correct objectives in it
• If you are building your own focus stacking rail (e.g. with a stepper motor)

Leitz Wetzlar microscope objective with a unique 13x magnification.

Manufacturer: Leitz Wetzlar
Magnification: 13x
Color correction: achromat
Number in the manufacturer's 1967 catalog: 519 237 (alternative notation: 519237)
Numerical aperture N.A.: 0.40
Tube length: 170 mm
Parfocal length: 37 mm
Working distance: 3.4 mm
Cover glass: either - the objective works both without and with a cover glass
Immersion: no (dry objective)
Thread: RMS

Because it works without a cover glass and has a high numerical aperture N.A., this objective can be attractive for macro photographers. It allows projection directly onto the camera sensor - without any intermediate optics.

This objective was removed from a Leitz SM microscope, but it fits most Leitz Wetzlar microscopes made before roughly 1980 (SM, SM-D, SM-Lux, Dialux, Ortholux, Orthoplan, etc.).

Some useful information about Leitz Wetzlar objectives with TL=170 mm and 37 mm parfocal length:
- most Leitz microscopes made before roughly 1980 accept objectives for both 160 mm and 170 mm tube length
- many Leitz microscopes accept objectives with both 37 mm and 45 mm parfocal length
- with an 8 mm RMS extension adapter, such an objective gets a parfocal length of 45 mm. Leitz made such adapters under the name "Plezy" - but many users make their own, from metal or on 3D printers

Like a large share of microscope objectives made in Germany in the 1960s and 1970s, this objective has a 37 mm parfocal length and a 170 mm tube length. For this reason it is often used as a replacement objective for other German microscopes, e.g.:
- Steindorff Berlin
- Kremp Wetzlar
- Hertel & Reuss
- Steinmar Berlin
- CBS Beck Kassel
- ROW Rathenow

This objective fits practically any microscope from any manufacturer, as long as it has an RMS thread and accepts objectives with TL=170 mm and a parfocal length of 33 / 37 mm (or 45 mm with a suitable adapter). Some examples of such microscopes are listed in the "compatibility" section, but this list is not complete.

What is this part needed for?

• if you own a Leitz Wetzlar microscope and this is exactly the objective missing from your set
• if you already have such an objective in your microscope, but it is in very poor condition or damaged
• if you want to keep such an objective as a spare
• if you want to use this objective on another, compatible microscope
• if you want to use this objective for macro photography at a 13:1 reproduction ratio

This is description of this part:

Achromatic Steindorff Berlin microscope objective with 40x magnification for brightfield and phase contrast.

Manufacturer: Steindorff Berlin
Model: Ph 40/0,65
Magnification: 40x
Correction: achromatic
Numerical aperture N.A.: 0.65
Tube length: 170 mm
Parfocal length: 37 mm
Cover glass: yes, 0.17 mm thick
Immersion: no (dry objective)
Thread: RMS
Phase contrast: yes - the objective has a built-in phase ring

Older Steindorff Berlin microscope models had a phase contrast condenser consisting of a standard brightfield condenser with a swing-out set of annular stops mounted below it (see here: https://www.facebook.com/groups/136833493390496/posts/1722963914777438/). It is not certain that this objective will match that condenser, because the annular stop there is marked 45x, while the objective offered here is 40x.

Only the Steindorff Berlin turret condenser (see here: https://www.facebook.com/groups/136833493390496/posts/1746808269059669/) has a 40x annular stop, and this objective is compatible with it.

I am not aware of Steindorff Berlin "Ph" objectives working with phase contrast condensers from other manufacturers. Please note: "not aware" does not mean they do not fit - but it is safer to assume they do not. In other words, you should assume that this objective will form a working set only with a Steindorff Berlin phase contrast condenser.

What is this part needed for?

• if you own a Steindorff Berlin microscope with a matching phase contrast condenser and this is exactly the objective missing from your set
• if you already have such an objective in your microscope, but it is in very poor condition or damaged
• if you want to keep such an objective as a spare

External control console for the Leica DSC1 rotary disc microtome

Basic parameters of this control panel:
Manufacturer: Leica Biosystems
Manufacturer catalogue number: 14050534242 / 14050534241 depending on version
Fits: Leica DSC1 rotary disc microtome (catalogue number of the microtome: 14050533151)
Connection: the panel is fitted with a cable terminated in a 9-pin D-Sub socket (DB9, female)

The control panel offered here is an add-on component for the Leica DSC1 microtome. It gives fuller control over the sectioning parameters than the buttons on the front of the microtome housing.

This panel provides the following functions:
- setting the section thickness (SECT) and the trimming thickness (TRIM) in µm with the "-" and "+" keys
- adjusting the sectioning speed with the SPEED knob
- switching the operating mode with the TRIM/SECT key
- automatic approach of the block to the knife (AUTO APPROACH)
- starting and stopping the cutting motion with RUN/STOP pressed together with ENABLE
- moving the object head to the specimen change position (CHANGE OBJECT)
- coarse feed towards and away from the knife, at two speeds
- storing the working position with the SET key and returning to the base position (HOME)
- two three-digit displays, TRIM and SECT, showing the thickness in µm or the speed
- indicator lamps for drive status (MOT), stop (STOP), base position (HOME) and emergency stop (E-STOP)
- connection to the main unit of the microtome by a cable with a D-Sub 9-pin connector

Because this is an external component (plugged into the DB9 socket of the microtome), it is very often missing from microtomes offered on the second-hand market.

What is this part needed for?

• if you have a Leica DSC1 microtome without the external control console
• if you have such a console but it is damaged or in very poor condition
• if you want to keep this control panel as a spare

This is description of this part:

Carl Zeiss Jena plan compensating microscope eyepieces with 16x magnification

Manufacturer: Carl Zeiss Jena
Model: PK 16x (12)
Magnification: 16x
Field of view number: 12
Mounting diameter: 23.2 mm
Designation: PK = plan compensating - recommended for work with planachromatic objectives, but they also work without any trouble with achromats or apochromats

Because of their very high quality they are often used on microscopes from other manufacturers as well, especially when Carl Zeiss Jena Planachromat objectives are mounted in them. The "compatibility" section lists a long series of microscopes these eyepieces fit - but that list is definitely not complete.

Important: these eyepieces work both on microscopes with a finite tube length (160 mm, for example) and on microscopes with infinity optics. That means you can use them on the Carl Zeiss Jena Amplival microscope just as well as on the Carl Zeiss Jena NU-2 microscope.

A note - eyepieces with such a strong magnification are in my opinion better suited to a quick look than to permanent work. I write "in my opinion" on purpose, because this comes from using them and not from the manufacturer's description.
A 16x eyepiece magnification should be treated as a zoom that brings out no additional detail (the resolution is not increased). This matters for example with heads that have their own extra magnification (such as Carl Zeiss Jena heads with a built-in 1.5x or 1.6x factor) - working with a 100x oil immersion objective you then theoretically get 100*1.5*16 = 2400x, while physics does not allow light from the visible range to be usefully magnified for the human eye beyond roughly 1250x - so this is what is called empty magnification.

What is this part needed for?

• if you don't have these eyepieces in your set
• if you have 16x eyepieces, but they have a smaller field of view
• if you want to replace your poor-quality eyepieces
• if you have Planachromat objectives and want to use plan-compensated eyepieces

This is description of this part:

Carl Zeiss Jena plan compensating microscope eyepieces with 12,5x magnification

Manufacturer: Carl Zeiss Jena
Model: PK 12,5x (16)
Magnification: 12,5x
Field of view number: 16
Mounting diameter: 23.2 mm
Designation: PK = plan compensating - recommended for work with planachromatic objectives, but they also work without any trouble with achromats or apochromats

Because of their very high quality they are often used on microscopes from other manufacturers as well, especially when Carl Zeiss Jena Planachromat objectives are mounted in them. The "compatibility" section lists a long series of microscopes these eyepieces fit - but that list is definitely not complete.

Important: these eyepieces work both on microscopes with a finite tube length (160 mm, for example) and on microscopes with infinity optics. That means you can use them on the Carl Zeiss Jena Amplival microscope just as well as on the Carl Zeiss Jena NU-2 microscope.

What is this part needed for?

• if you don't have these eyepieces in your set
• if you have 12,5x eyepieces, but they have a smaller field of view
• if you want to replace your poor-quality eyepieces
• if you have Planachromat objectives and want to use plan-compensated eyepieces

This is description of this part:

Original grease for servicing Carl Zeiss Jena microscopes, type Gleitfett III E410.

I have not managed to find any documentation describing how the individual Gleitfett grades differ in their parameters.

Gleitfett I E10 and Gleitfett II E75 were supplied with the Carl Zeiss Jena micromanipulator.
The Gleitfett III E410 offered here was supplied with the Carl Zeiss Jena Neophot-21 microscope.

This MAY suggest (although I have no proof in the form of manufacturer documentation) that the lower numbers (I and II) and the lower values of the "E" parameter (E10 and E75) were intended for finer mechanisms - and may therefore have a lower viscosity, for example. The III E410 grease, with its high "E" value, was supplied with a heavy microscope built around massive mechanics - so it may well be thicker.

This grease can of course be used on microscopes from other manufacturers as well - a few are listed in the "compatibility" section, but that is by no means a complete list.

What is this part needed for?

• When you need to service your microscope or microscope component and need to replace the lubricants (grease).

Planachromatic microscope objective with 40x magnification for the Motic BA210 and BA310 microscopes.

Manufacturer: Motic
Marking on the objective: Motic EF-N Plan 40x/0.65 ∞/0.17
Magnification: 40x
Correction: PLAN achromatic
Optical system: CCIS (Color Corrected Infinity System - part of the image correction is performed by the tube lens of the Motic stand, which is why the objective is intended for stands of this brand)
Numerical aperture N.A.: 0.65
Working distance W.D.: approx. 0.4-0.5 mm
Tube length: infinity
Parfocal distance: 45 mm
Field number F.N.: 20
Cover glass: yes, 0.17 mm thick
Immersion: no (this is a dry objective)
Thread: RMS
Spring-loaded mount: yes - the front mount retracts when pressed against the specimen, which at a working distance of about half a millimetre saves both the objective and the cover glass
Lead-free glass: yes - the mount carries the crossed-out Pb symbol
Colour ring: blue, according to the colour code for 40x magnification

Objectives of the EF-N Plan series were the factory equipment of the older generation of the Motic BA210 and BA310 microscopes, while the newer models of these series, designated Elite (BA210E, BA310E), are fitted with the next-generation EC Plan objectives - this objective is therefore the correct spare part for the older stands and not for the Elite versions.

Mechanically this objective can be screwed into the nosepiece of many other microscopes, since the RMS thread and the 45 mm parfocal distance are standard - a correct image, however, cannot be obtained that way.
- in older stands corrected for 160 mm it will not work, because it is an infinity-corrected objective and requires a tube lens
- in stands of other manufacturers, including infinity-corrected ones, a residual aberration remains, because part of the correction is performed by the tube lens of the CCIS system, which is built into the stand of the Motic microscope and matched by the manufacturer to exactly this optics
- in the remaining Motic microscopes with the CCIS system the objective does produce an image, but it is not the factory choice for them - in stands with field number 22 it runs out of field, and in inverted stands it runs out of working distance.

What is this part needed for?

• if you own the Motic BA210 / Motic BA310 microscope and this objective is missing
• if you already have such an objective in your microscope, but it is in very poor condition or damaged
• if you want to have such an objective as a spare

Leitz Wetzlar projection microscope eyepiece with 4x magnification

Manufacturer: Leitz Wetzlar (Germany)
Marking on the eyepiece: Proj. 4x
Magnification: 4x
Kind: projection eyepiece for photomicrography
Intended for: microscopes corrected for objectives with TL = 170 mm
Mounting diameter: 23.2 mm

Projection eyepieces are special microscope eyepieces used to project the microscopic image onto the sensor of a camera. Many microscope photo tubes and trinocular heads have a seat for a projection eyepiece.

Leitz projection eyepieces of this magnification carry several different markings. You will find "Proj.-Ok. H4x", "Proj.-Ok. P4X" and - as on the item offered here - simply "Proj. 4x". The letter H stands for the Huygens design. Leitz also made projection eyepieces of other magnifications, 2.5x among them, so the 4x version is not the only one in this family.

The eyepiece is intended for microscopes with a mechanical tube length of 170 mm. The older Leitz stands are corrected this way, Orthoplan, Ortholux, SM and SM-D among others. Later microscopes of this brand already work with a 160 mm tube. In Leitz optics of this generation part of the chromatic aberration correction is deliberately moved from the objective to the eyepiece, so matching an eyepiece to an objective is not merely a mechanical question here.

Despite its name, this eyepiece behaves differently from a typical projection eyepiece. It does not form a real image at a fixed distance, but projects the image to infinity - exactly like an ordinary viewing eyepiece. This makes it excellent for the afocal method, that is, photographing with a camera that keeps its own lens placed above the eyepiece. Leitz itself built its photographic adapters on precisely this method.

Leitz "Proj." eyepieces also found use outside microscopy. Eyepieces of this family were part of the microprojection attachments for the Leitz Prado and Pradovit projectors, which threw the image of a specimen onto a screen for a whole lecture room. If you are completing such an attachment, this is exactly the part.

Use in a microscope with a 160 mm tube length remains a matter of your own DIY modification. Mechanically the eyepiece fits any 23.2 mm seat, but the intermediate image is then formed in a different place, so focus and image scale will come out differently from what the manufacturer intended. There is, however, a route that gives a beautiful combination: into a microscope of another manufacturer you fit a Leitz Wetzlar objective computed for 170 mm, and this eyepiece above it. The optical path is then entirely Leitz - objective and eyepiece work as they were designed to, and only the stand remains foreign, a PZO or a Carl Zeiss Jena one for instance.

The "compatibility" section lists the microscope models this eyepiece can be used with, but that list is of course not complete. This projection eyepiece can be used with any microscope of any manufacturer, as long as it has a tube or another seat for an eyepiece of 23.2 mm diameter - subject to the difference between 160 and 170 mm tube length (I write about this above).

What is this part needed for?

• if your microscope has a photo tube or a trinocular head with a 23.2 mm seat and you want to take photographs using a projection eyepiece
• if you already have such an eyepiece, but it is damaged, scratched or has fungus on the lenses
• if you want to keep a projection eyepiece as a spare
• if you are completing a microprojection attachment for a Leitz Prado or Pradovit and the eyepiece is missing from it
• if you have an older Leitz microscope for a 170 mm tube and want to photograph the way the manufacturer intended
• if you need a compensating eyepiece for photomicrography, because your Leitz objectives leave part of the chromatic aberration correction to the eyepiece
• if you want to use this eyepiece in a microscope of another manufacturer together with a Leitz Wetzlar objective computed for 170 mm
• if you are trying out projection eyepieces of different magnifications to find the best one for your microscope and camera combination - and you want to test this one
• if you have neither a photo tube nor a trinocular head, but want to use the eyepiece for photomicrography through the eyepiece tube

This is description of this part:

Achromatic oil immersion microscope objective made by Nikon, with 100x magnification and a 45 mm parfocal length.

Manufacturer: Nikon (Japan)
Magnification: 100x
Colour correction: achromatic
Model: E. 100 1.25 oil 160/0.17
Numerical aperture N.A.: 1.25
Cover glass: yes, 0.17 mm thick
Thread: RMS
Tube length: 160 mm
Parfocal length: 45 mm (long barrel objective)
Immersion: yes, oil
Operating mode: objectives marked "E." are already CF objectives (CFN to be precise) and need no additional correction

This objective needs no additional correction from a tube lens or from the eyepieces. That makes it possible to fit it to microscopes of other makes, and in photomicrography it works in direct projection mode (it throws the image straight onto the camera sensor, with no relay optics needed).

This is the so-called black series of objectives, named after the black plastic barrel. They were used mainly in the Nikon Alphaphot YS2 microscope. That was the period when manufacturers were experimenting with a new look for microscope parts, and exactly the same black series appeared for instance in the Leitz / Leica HM-LUX 3 microscope or in the Will Wetzlar V300 / V355 / V365 microscopes.

This objective fits practically any microscope of any make, provided it has an RMS thread and supports objectives with TL = 160 mm and parfocal lengths of 33 / 37 and 45 mm. A few such microscopes are listed in the "compatibility" section, but that list is not complete.

What is this part needed for?

• if you have a Nikon Alphaphot YS2 microscope without a 100x objective and want to complete it with original parts
• if you are looking for a good-quality 100x objective for a microscope from another manufacturer
• if you already have such an objective, but it is of very poor quality and you want to replace it with a working one
• if you want to keep such objective in reserve

This is description of this part:

Achromatic microscope objective made by Nikon, with 40x magnification and a 45 mm parfocal length.

Manufacturer: Nikon (Japan)
Magnification: 40x
Colour correction: achromatic
Model: E 40 0.65 160/0.17
Numerical aperture N.A.: 0.65
Cover glass: yes, 0.17 mm thick
Thread: RMS
Tube length: 160 mm
Parfocal length: 45 mm (long barrel objective)
Immersion: no
Operating mode: objectives marked "E." are already CF objectives (CFN to be precise) and need no additional correction

This objective needs no additional correction from a tube lens or from the eyepieces. That makes it possible to fit it to microscopes of other makes, and in photomicrography it works in direct projection mode (it throws the image straight onto the camera sensor, with no relay optics needed).

This is the so-called black series of objectives, named after the black plastic barrel. They were used mainly in the Nikon Alphaphot YS2 microscope. That was the period when manufacturers were experimenting with a new look for microscope parts, and exactly the same black series appeared for instance in the Leitz / Leica HM-LUX 3 microscope or in the Will Wetzlar V300 / V355 / V365 microscopes.

This objective fits practically any microscope of any make, provided it has an RMS thread and supports objectives with TL = 160 mm and parfocal lengths of 33 / 37 and 45 mm. A few such microscopes are listed in the "compatibility" section, but that list is not complete.

What is this part needed for?

• if you have a Nikon Alphaphot YS2 microscope without a 40x objective and want to complete it with original parts
• if you are looking for a good-quality 40x objective for a microscope from another manufacturer
• if you already have such an objective, but it is of very poor quality and you want to replace it with a working one

This is description of this part:

Achromatic Meopta microscope objective with 10x magnification, for brightfield and phase contrast work.

Manufacturer: Meopta (Prague, former Czechoslovakia)
Marking on the objective: Ph10 0.30
Magnification: 10x
Colour correction: achromatic
Numerical aperture N.A.: 0.30
Cover glass: does not matter - an objective of this magnification can work both without and with a cover glass
Thread: RMS
Tube length: 170 mm
Parfocal length: 37 mm (so-called short barrel objective)
Immersion: no
Phase contrast: yes - the objective has a phase ring inside

A 10x objective does not need a cover glass to work, but it is worth mentioning that Meopta microscope objectives were designed for cover glasses 0.18 mm thick - while the vast majority of manufacturers corrected their objectives for 0.17 mm. This matters with selected cover glasses that keep to the standard. With cheap Chinese cover glasses, whose thickness can vary considerably within a single pack, it practically stops mattering.

For this objective to work in phase contrast, a Meopta phase contrast condenser with matching annulus sizes is required.

Can this objective, despite the "Ph" marking, work without phase contrast, that is in "normal" brightfield? Yes - and this is the rule for all phase objectives, from any manufacturer: such an objective can be used in brightfield, but with slightly worse contrast. From my experience I would say the difference is not noticeable "to the eye".

What is this part needed for?

• if you own a Meopta microscope with a phase contrast condenser but without the 10x objective and you want to complete it with original parts
• if you already have such an objective, but it is in very poor condition and you want to replace it with a working one
• if you want to keep such an objective as a spare
• if you want to use the complete Meopta phase contrast set with a microscope from another manufacturer

This is description of this part:

Export version of a LOMO (ЛОМО) microscope objective with 40x magnification.

Basic parameters of this objective:
Manufacturer: Lomo (ЛОМО)
Version: this is the OEM version of this objective; it was made for export and has no engraved manufacturer logo
Magnification: 40x
Correction: achromatic
Marking on the objective: 40 0,65
Numerical aperture N.A.: 0,65
Tube length: 160 mm
Parfocal length: 33 mm - so-called short barrel objective
Cover glass: yes, 0.17 mm thick
Immersion: no
Specimen protection: yes, the objective has a spring-loaded front mount that prevents breaking the slide
Thread: RMS

LOMO exported its microscopes to Western Europe, where they were sold under the names Bresser Biolam / Bresser Erudit (mainly in Germany) and Zenith Biolam (in the UK). These microscopes often (but not always) came with special versions of the objectives without the "ЛОМО" engraving.

A note on the Bresser Erudit microscope: Bresser sold two different microscopes under this name. The first was a Lomo microscope labelled "Bresser Erudit", the second is the plastic, Chinese-made "Bresser Erudit DLX" microscope.
The microscope objective offered here fits the first of these two Erudit microscopes. A photo gallery of the first model can be found here: https://www.microscopeparts.eu/gallery/lomo-erudit-microscopes-207.

This is a so-called short barrel objective with a parfocal length of 33 mm. It is very often mounted on a 12 mm extension, which allows it to be used in microscopes that require objectives with a 45 mm parfocal length. Professional adapters with protective optics, metal adapters and popular DIY 3D-printed adapters all work well here.

LOMO objectives are very popular with owners of microscopes from other manufacturers. Due to historical ties, owners of Carl Zeiss Jena microscopes regard them as an obvious replacement for the German objectives.

This objective fits practically any microscope from any manufacturer, as long as it has an RMS thread and accepts objectives with TL = 160 mm and 33 mm parfocal length (or 37 / 45 mm with a suitable adapter). Several example microscopes are listed in the "compatibility" section, but the list is not complete.

What is this part needed for?

• If you want to complete your Bresser Biolam / Lomo Biolam microscope with original parts
• If you need a 40x objective for Bresser, Lomo, Carl Zeiss Jena, Euromex or other compatible microscopes

This is description of this part:

Carl Zeiss Jena photo tube / camera adapter - also fitting microscopes from other makers: LOMO, Meopta, Olympus, IOR.

The tube allows a camera or a camera body to be attached to a trinocular head or directly to the microscope body, even when there is no trinocular head.

Basic technical parameters of this tube:
Manufacturer: Carl Zeiss Jena
Colour: grey
Tilt angle: none, this is a straight tube
Internal optics: none - not even a deflecting prism
Mounting to the trinocular head or microscope body: ring with a dovetail
Dovetail diameter: 41 mm
Type of connection at the output: empty tube / barrel
Tube diameter at the output: 23.2 mm internal diameter
Length of the barrel / tube: 25 mm
Length adjustment: no - this is not a tube with adjustable height

Since the adapter has an empty barrel with an internal diameter of 23.2 mm on the output side, a projection eyepiece of that diameter can be placed in it, or a so-called "USB eyepiece", that is a digital microscope camera. Adapters between the 23.2 mm barrel and the M42 thread are also widely available, and from the M42 thread you can move on to any other mount: Nikon, Canon, Sony and others.

Such a tube can be mounted directly on the microscope body instead of the head. A dovetail seat with a diameter of 41.0 - 41.5 mm is found, among others, on the microscopes:
- Carl Zeiss Jena
- LOMO
- Meopta
- IOR
- Reichert Biopan
- Olympus CH

It is also often used in microscopes with a slightly larger seat, among others Zeiss West Germany, Leitz Wetzlar, PZO, Will Wetzlar, Hund Wetzlar.

The adapter can equally well be fitted onto trinocular heads, as many of them have a seat prepared for it, among others:
- the output in the trinocular tubes of the Carl Zeiss Jena Jenamed, Jenaval, Jenalumar, Jenatech, Jenavert, Jenapol microscopes
- the LOMO TRN-1 heads (ЛОМО ТРН-1), found in the LOMO Polam microscopes
- some versions of the intermediate photo tubes for the Carl Zeiss Jena Mikroval series microscopes (others require a tube screwed onto a thread)

This is not a "tube for one specific microscope model". A trinocular head can be mounted not only on the microscope it was sold with - it is therefore correct to assume that this is a universal tube, with a 41 mm dovetail on one side and a 23.2 mm barrel on the other.

The "compatibility" section gives an example list of microscopes this tube fits, although it is not a complete list.

What is this part needed for?

• if you need a tube that allows a camera or photographic camera to be connected to a trinocular head
• if you need to connect a camera or photographic camera directly to the microscope body

This is description of this part:

LOMO 140 - 200 mm photo tube / camera adapter with adjustable length - but also fitting many other microscopes from Carl Zeiss Jena, Meopta, Olympus, IOR and others.

The tube allows a camera or a camera body to be attached to a trinocular head or directly to the microscope body, even when there is no trinocular head.

Basic technical parameters of this tube:
Manufacturer: LOMO (ЛОМО)
Colour: black, rings and barrel chrome-plated
Tilt angle: none, this is a straight tube
Internal optics: none - not even a deflecting prism
Mounting to the trinocular head or microscope body: ring dovetail (male part)
Dovetail diameter: 41 mm
Type of connection at the output: empty tube / barrel
Tube diameter at the output: 23.2 mm internal diameter
Length of the barrel / tube: variable
Length adjustment: yes - the barrel is extendable, with a scale from 140 to 200 mm and a knurled locking ring

This is the version with adjustable tube length. A scale from 140 to 200 mm is engraved on the extendable barrel, with a reference line and intermediate divisions, and the setting is locked with a knurled ring. This gives two things at once. First, a continuous change of the image scale - the longer the tube, the larger the image falling on the sensor or the film, so the framing can be adjusted without changing the objective. Second, and more importantly, the ability to work with objectives computed for different optical tube lengths: 160, 170, 180, 190 and 200 mm. Carl Zeiss Jena and LOMO objectives are computed for 160 mm, Leitz Wetzlar for 170 mm, some objectives of metallurgical and measuring microscopes for 190 or 200 mm - here you simply set the barrel to the right value and the objective works under its design conditions, instead of delivering an image with residual aberration.

Since the adapter has an empty barrel with an internal diameter of 23.2 mm on the output side, a projection eyepiece of that diameter can be placed in it, or a so-called "USB eyepiece", that is a digital microscope camera. Adapters between the 23.2 mm barrel and the M42 thread are also widely available, and from the M42 thread you can move on to any other mount: Nikon, Canon, Sony and others.

Such a tube can be mounted directly on the microscope body instead of the head. A dovetail seat with a diameter of 41.0 - 41.5 mm is found, among others, on the microscopes:
- LOMO
- Carl Zeiss Jena
- Meopta
- IOR
- Reichert Biopan
- Olympus CH

It is also often used in microscopes with a slightly larger seat, among others Zeiss West Germany, Leitz Wetzlar, PZO, Will Wetzlar, Hund Wetzlar.

The "compatibility" section gives an example list of microscopes this tube fits, although it is not a complete list.

The last photo shows a LOMO Erudit microscope with this photo tube and a projection eyepiece mounted. It is an example of use.

What is this part needed for?

• if you need a tube that allows a camera or a camera body to be attached to a trinocular head
• if you need to attach a camera or a camera body directly to the microscope body, because you have no trinocular head or want to photograph without splitting the light
• if you have objectives computed for a different tube length than your microscope - 170 mm from Leitz, 190 or 200 mm from a metallurgical microscope - and want to finally use them under their own conditions
• if you want to change the framing and the image scale without changing the objective and without swapping the projection eyepiece
• if you want to choose the magnification so that the image fills the camera sensor and the dark corners disappear
• if your old photo tube has been lost, sold separately or has a damaged connection

Work in brightfield without phase contrast: possible, but even the manufacturer states in the manual that the image quality is worse than with an objective without phase rings inside

A very important note: two phase rings inside an objective bring to mind variable phase contrast (PhZ at PZO or PhV at Carl Zeiss Jena). With LOMO, however, this is rather something like a "second type of positive phase contrast". LOMO states in the manual (https://laboratorium.dp.ua/item/68) that one image is obtained when light passes through both rings (with the condenser iris diaphragm open) - and a different one when the diaphragm is closed far enough that light no longer reaches the outer, wide ring and only the inner ring works. The manufacturer recommends viewing the specimen in both modes, because together they give a more reliable idea of its structure. The contrast stays positive (thicker or denser parts of the specimen appear darker against a bright background), and both modes differ from work with the single-ring "Ф" objectives and the LOMO KF-4 condenser (ЛОМО KФ-4), where both the objective and the condenser diaphragm have only one ring. So the resulting effect does change - but this is not variable phase contrast; the change is stepwise (either-or), not continuous.

The objective presented here fits the LOMO KF-5 condenser (ЛОМО KФ-5). That condenser has a mounting diameter of 37 mm and is very often used on microscopes from other makers, among them Carl Zeiss Jena and Olympus (especially Olympus CH). With a suitable build-up ring fitted (3D printed, for example), this condenser is commonly used in microscopes with a 39,5 mm condenser seat as well. The instructions for setting up LOMO KF-5 phase contrast can be found here: https://scopica.ru/proj/ustroystvo-dlya-nablyudeniya-metodom-fazovogo-kontrasta-kf-5/

This is a so-called short barrel objective, with a parfocal length of 33 mm. It is very commonly mounted on a 12 mm extension, which allows it to be used in microscopes that require objectives of 45 mm length. Professional adapters with protective optics, metal adapters and the popular 3D printed DIY solutions all work here.

LOMO objectives are very popular with owners of microscopes from other makers. Because of the historical links, owners of Carl Zeiss Jena microscopes treat them as an obvious substitute for those German objectives.

This objective fits practically any microscope from any maker, provided it has an RMS thread and accepts objectives with TL=160 mm and a parfocal length of 33 mm (or 37 / 45 mm if a suitable adapter is used). A few such microscopes are listed in the "compatibility" section, but that is not a complete list.

What is this part needed for?

• if you own a microscope with the LOMO KF-5 phase contrast condenser but are missing the 40x F-2 objective from the set
• if you have such a set, but the LOMO 40x F-2 objective in it is damaged or in very poor condition
• if you are curious about this variety of phase contrast and want to experiment with this objective on other condensers, to get interesting and non-obvious results

This is description of this part:

Carl Zeiss Jena Planachromat 25x microscope objective with M19 thread, for infinity systems, for work without a cover glass.

Basic parameters:
Manufacturer: Carl Zeiss Jena
Engraving on the objective: Planachromat 25x/0,50 ∞/0
Magnification: 25x
Numerical aperture N.A.: 0,50
Free working distance: 3,1 mm
Tube length: infinity (more precisely: 250 mm)
Optical correction: planachromatic
Cover glass: no - this objective is intended for work without a cover glass
Immersion: no - this is a so-called dry objective
Phase contrast: no - this objective has no phase ring inside
Polarisation: no - this is not a polarising objective
Thread: M19
Plan compensating eyepieces: yes, required - this objective calls for eyepieces with additional correction (designated "PK" by Carl Zeiss Jena)
Direct projection and macro photography: no - this objective does not work in direct projection mode and is not suitable for macro photography by connecting the objective directly to a camera

This objective can be used as:
- an objective for work in reflected light (EPI), for biological as well as, among others, metallurgical or mineralogical applications
- an objective for work in transmitted light, among others with biological specimens or, for example, with mineralogical thin sections

A few facts about Carl Zeiss Jena objectives with M19 thread (CZJ M19) and their compatibility with various microscopes of this company:
- these objectives serve mostly technical applications and are intended for work without a cover glass (marking ∞/0)
- CZJ M19 objectives intended for biological applications (that is, marked ∞/0,17) are most often used on Carl Zeiss Jena NU / NU2 microscopes
- in Carl Zeiss Jena Nf and Lumipan microscopes, CZJ M19 objectives are used together with the EPI illuminator and can then work both in bright field and in dark field
- in Carl Zeiss Jena Polmi-A microscopes, CZJ M19 objectives can be used, but they give a magnification other than the nominal one
- Carl Zeiss Jena Amplival / Amplival Pol / Amplival Interphako / Peraval microscopes have an interchangeable nosepiece, and there is also a nosepiece intended for these microscopes that accepts objectives with M19 thread
- Carl Zeiss Jena Metaval microscopes use newer versions of CZJ M19 objectives (those with a coarsely knurled rim and a glossy barrel), yet many people experiment with older M19 objectives on these microscopes
- Carl Zeiss Jena Epignost and BK 70x50 microscopes were produced in various configurations - and some work with CZJ M19 objectives
- Carl Zeiss Jena Vertival / Epival / Nf / BK 70x50 microscopes often allow work with CZJ M19 objectives in EPI dark field mode
- on inverted metallographic Carl Zeiss Jena Epityp-2 / Neophot-21 microscopes, many people use biological objectives intended for work with a cover glass alongside metallurgical ones, and place the slide with the specimen on the stage "upside down", that is, with the cover glass facing downwards

This is description of this part:

Carl Zeiss Jena Planachromat 25x microscope objective with a special kind of phase contrast for work in reflected light (EPI), intended for the Carl Zeiss Jena Neophot 21 microscope.

Basic parameters:
Manufacturer: Carl Zeiss Jena
Engraving on the objective: Planachromat 25x/0,50 ∞/0 Ph
Magnification: 25x
Numerical aperture N.A.: 0,50
Tube length: infinity (more precisely: 250 mm)
Optical correction: planachromatic
Cover glass: no - this objective is intended for work without a cover glass
Immersion: no - this is a so-called dry objective
Phase contrast: yes, a special phase contrast for work in reflected light
Polarisation: no - this is not a polarising objective
Thread: M19
Plan compensating eyepieces: yes, required - this objective needs eyepieces with additional correction (marked "PK" at Carl Zeiss Jena)
Direct projection and macro photography: no - this objective does not work in direct projection mode and is not suitable for macro photography with the objective attached directly to a camera

Phase contrast objectives for the Neophot microscopes have a phase ring built differently from the other Ph objectives made by Carl Zeiss Jena - instead of a continuous ring there is a three-segment pattern, somewhat reminiscent of a Wankel engine rotor. This is worth knowing, because it means that a phase contrast objective from a biological microscope will not replace this one in a Neophot, and the other way round.

The reason is a matter of design. In a metallurgical microscope the objective also acts as the condenser, so the illuminating light passes through the same pupil as the light forming the image. With a continuous ring the whole illumination would pass through the phase coating, which lets only part of the light through and reflects a fair amount of it - and those reflections would swamp the already faint phase contrast image. The solution turned out to be an odd number of segments: the image of the diaphragm formed after reflection off the specimen is rotated by 180 degrees, so with three segments it falls into the gaps between them. The illuminating light therefore enters beside the phase coating and returns through it. The solution is described in patent AT 295883 B.

The objective is offered together with its matching slider (Objektivwechselschlitten) with an M19 thread - and that is no coincidence. The position in which the phase sectors come to rest is decided by how far the objective screws into the thread, and every specimen stops slightly differently, which is why the factory selected objective and slider in pairs and wrote both numbers on the card in the case. Buying such a pair together avoids the whole problem - the objective already sits in relation to its slider exactly as it left the works.

Setting it up in the microscope needs neither a service technician nor a phase telescope - the Neophot has a built-in, swing-out Bertrand lens. The procedure is basically this: switch in the Bertrand lens, focus on the phase sectors and use the adjusting screws to bring the image of the sector diaphragm into coincidence with the image of the sectors in the objective; sometimes a slight rotation of the aperture diaphragm helps as well. Should the position of the glass in the sector diaphragm itself ever need correcting - it is held down by an ordinary threaded ring, so it can be turned. The whole thing resembles centring the phase rings in the condenser of a biological microscope.

Two more things are needed on the microscope side for work in phase contrast: the sector diaphragm (Sektorenblende), pushed in front of the open aperture diaphragm, and the auxiliary lens turret (Hilfslinsenrevolver) on the dovetail of the illuminator. The latter images the diaphragm exactly in the plane of the phase coating, which lies slightly differently in each objective - hence a separate auxiliary lens for every magnification. In bright field the objective of course works perfectly normally.

A note for the DIY-minded: an objective like this can be adapted for transmitted light, except that the diaphragm in the condenser is then set not opposite but in line with the segments of the objective, because there is no second pass through the pupil. Phase contrast should appear, but with stronger halo and a directional relief effect, since the gaps in the ring mean that part of the illumination azimuths is missing. On top of that comes the infinity design with no cover glass correction, so a tube lens will be needed. More of an experiment than a working solution - but doable in one evening.

The last photos in the gallery show:

* a photo of the original table indicating which serial numbers of the objective sliders are factory-paired with which serial numbers of the objectives
* two pages of errata to the instruction manual of the Carl Zeiss Jena Neophot 2 microscope.

The "compatibility" section lists, besides the Carl Zeiss Jena Neophot 21 microscope, those microscopes that this objective fits mechanically and optically. What result you get on them, however, can sometimes be a surprise.

Here (https://www.microscopeparts.eu/part/91056) is the same objective in the version without phase rings. Its description tells you more about using Carl Zeiss Jena objectives with an M19 thread.

What is this part needed for?

• if you own a Carl Zeiss Jena Neophot 21 microscope with phase contrast but are missing the 25x objective from the set
• if you own the complete set but your 25x objective is damaged or in very poor condition
• if you like to be prepared and want such an objective in reserve, as it rarely turns up on the second-hand market
• if you are putting together a phase contrast set of this kind yourself and sourcing every part separately
• if you need an objective of this magnification for one of the microscopes it works with (further details are given in the description)

This is description of this part:

Carl Zeiss (West Germany) microscope objective with 40x magnification, for Ph2 phase contrast.

Basic parameters:
Manufacturer: Carl Zeiss West Germany
Designation: Ph2 F40/0,65 160/0,17
Manufacturer catalogue number: 46 07 06
Magnification: 40x
Correction: Semi-planachromatic
Numerical aperture N.A.: 0.65
Tube length: 160 mm
Parfocal length: 45 mm
Cover glass: yes, 0.17 mm thick
Immersion: no (a so-called dry objective)
Thread: RMS
Phase contrast: yes, the objective has an internal phase ring matching the Ph2 position in the condenser
Specimen protection: yes, the objective has a spring-loaded mechanism that protects the slide from being crushed

The letter "F" at the beginning of the objective model name (F 40 / 0.65) means that this is a semi-planachromatic objective, i.e. flatter than an achromat but less flat than a planachromat. "F" does not mean that the objective is intended for work with fluorescence light.

This objective fits practically any microscope from any manufacturer, provided it has an RMS thread and accepts 160 mm tube length objectives with a parfocal length of 33, 37 or 45 mm. A few example microscopes are listed in the "compatibility" section, but that list is not complete.

What is this part needed for?

• If you have a microscope without objectives and need to restock it using original parts
• If you have a microscope that doesn't have an objective lens with this magnification and want to restock it
• If you have such an objective lens, but it's of very poor quality or damaged

Steindorff Berlin 100x immersion microscope objective

Basic parameters:
Manufacturer: Steindorff Berlin
Marking on the objective: Steindorff & Co̱ Berlin 1/12 = 100x Oel-Immersion
Magnification: 100x
Correction: achromatic
Tube length: not stated, most likely 170 mm
Cover glass: yes
Immersion: yes, oil
Thread: RMS

The objective does not state the numerical aperture N.A., but 100x oil immersion objectives usually have an N.A. of 1.20.

The microscope gallery on the steindorff-berlin.de website (https://steindorff-berlin.de/Instruments/Gallery/gallery.html) shows a microscope with serial number 54541, which suggests that objectives of this type were in use in the first half of the 1950s. The author of that same site explains here that from the 1950s onwards the year of manufacture should be read in this way: https://steindorff-berlin.de/Instruments/Microscopes/microscopes.html

This objective is finished in black and white styling. A decade earlier Steindorff still used brass objectives or ones in a gold and silver finish. On the objective shown here the company name appears as "Steindorff & Co̱", with the word "Berlin" on the second line; by the early 1960s, however, the objectives were entirely silver and carried the inscription "Steindorff Berlin" inside a border serving as the logo.

What is this part needed for?

• If you own a vintage Steindorff Berlin microscope that is missing this objective and you want to complete it with original period parts
• If you already have such an objective, but it is in very poor condition or damaged

Single WF 10x widefeld microscope eyepiece by Will Wetzlar

Microscope eyepiece (1 pc.)
Manufacturer: Will Wetzlar
Model: WF 10x
Magnification: 10x
Mounting diameter: 23.2 mm

Because this is important, I will write it again: this is a single eyepiece, not a pair of eyepieces.

This is a solution for people who:
- either have a pair of these eyepieces, but one of them needs to be replaced
- or have a microscope with a monocular head

For Will Wetzlar microscopes, eyepieces from practically any manufacturer can be used, provided that they are designed for a finite tube length system and have a mounting diameter of 23.2 mm. However, many users appreciate having original parts.

This eyepiece also works the other way around - it fits almost any microscope from any manufacturer that allows the use of eyepieces with a mounting diameter of 23.2 mm. Users of microscopes from many manufacturers are happy to choose German eyepieces because of their high quality. I have included some examples in the "compatibility" section, but this is definitely not a complete list.

Microscope users have several names for eyepieces of this type with a large field of view. Among others:
- wide field eyepiece
- widefield ocular
- WF eyepiece
- wide angle eyepiece
- large field of view eyepiece

What is this part needed for?

• if you have a Will Wetzlar microscope with a monocular head and are missing an eyepiece with this particular magnification
• if you have a microscope from another manufacturer and want to use this eyepiece
• if you have a pair of these WF 10x Will Wetzlar eyepieces, but one of them needs to be replaced due to poor condition or damage

This is description of this part:

Carl Zeiss blue matt microscope filter

Basic parameters of this microscope filter:
Manufacturer: Carl Zeiss West Germany
Name: Blauglas matt
Manufacturer catalogue number: 46 78 36 (also written as 467836)
Colour: blue matt
Diameter: 32 mm
Material: glass

This is a filter that combines the functions of a blue filter and a ground glass diffuser:
- the blue filter is used to convert the yellow, warm light of the bulb into light closer to white light
- the matt filter (called a diffuser or ground glass) is used to even out the light across the whole area of the specimen and to remove the visible filament of the bulb

This does, however, have one consequence: without a visible filament it is not possible to work with illumination set up according to the Koehler method - and Zeiss mentions this in the leaflet supplied with the filter.

Very often only one or two microscope filters can be fitted in a microscope, for example one on the illuminator and the second in the holder below the condenser. The fact that the glass filter offered here is a 2-in-1 solution makes it possible to save the possible second slot for another filter.

The diameter of 32 mm is a standard with many manufacturers, which means this filter can be used with microscopes of numerous brands. The "compatibility" section lists over a dozen such microscopes, but it is not a complete list.

What is this part needed for?

• if you need exactly this Zeiss filter P/N 467836 because you know its characteristics
• if you have a microscope with bulb illumination and want to shift the colour of the light closer to white
• if you already use a blue filter and a matt filter and would like to have both in a single piece of glass

This is description of this part:

Carl Zeiss Jena microscope objective with a low magnification of 8x.

This is one of many production variants of the 8x objective that were fitted to Carl Zeiss Jena microscopes over nearly 100 years. They differ in the appearance of the barrel and in the engraving.

Appearance of this variant of the Carl Zeiss Jena 8x objective:
- black section next to the thread
- silver upper section
- the marking "8/0,20 160/-" on one side of the silver part of the barrel
- the Carl Zeiss Jena logo and the serial number on the other side of the silver barrel

Here (https://www.microscopeparts.eu/part/99852) you will see the same Carl Zeiss Jena 8x objective, but in a slightly older variant (without the value "160/-" engraved on the barrel).

The Carl Zeiss Jena 8x objective is often used for macro photography - both on a microscope and on a camera (with an RMS adapter or a bellows unit). Although it is an achromatic objective, it renders fine detail very well and works nicely for focus stacking. It is a good complement to a set together with the Carl Zeiss Jena Semiplan 3.2x, LOMO 3.7x, Carl Zeiss Jena Semiplan 6.3x and Nikon M Plan 10x objectives.

Basic parameters of this objective:
Manufacturer: Carl Zeiss Jena
Magnification: 8x
Correction: achromatic
Marking on the objective: 8/0,20 160/-
Numerical aperture N.A.: 0.20
Serial number: above 580 000
Tube length: 160 mm
Parfocal length: 33 mm - a so-called short barrel objective
Cover glass: either way - objectives with such a low magnification can work both with and without a cover glass
Immersion: no (a so-called dry objective)
Thread: RMS

Important - this objective is suitable for taking pictures with the "direct-projection" technique, because it does not require plan-compensating optics.

A microscope objective with such a low magnification (keeping the 160 mm tube we get an 8:1 reproduction ratio) is used for observation or macro photography of, among other things:
- insects
- minerals
- inclusions in amber
- handwriting
- micro shells

Why do I describe the appearance of this variant so precisely in the description of this objective? Some users care about completing their Carl Zeiss Jena microscope with parts from the same series and roughly from the same period. The exact way the parameters are written on the barrel makes it possible to compare this objective not only from the photos in the gallery, but also at the level of the text description - especially for AI systems.

This is a so-called "short barrel objective", with a parfocal length of 33 mm. Very often this objective is mounted on a 12 mm extension, which makes it possible to use it in microscopes that require objectives with a parfocal length of 45 mm. Professional adapters with corrective optics work well here, as do plain metal adapters and the popular DIY parts from a 3D printer.

This objective fits practically any microscope from any manufacturer, provided it has an RMS thread and supports objectives with TL=160 mm and a parfocal length of 33 mm (or 37 / 45 mm if we use a suitable adapter). A few examples of such microscopes are listed in the "compatibility" section, but that is not a complete list.

Carl Zeiss Jena objectives are very popular among users of microscopes from other manufacturers. Because of the historical connections, owners of LOMO microscopes treat them as an obvious replacement for their own Soviet optics.

After the Second World War the Carl Zeiss Jena production plant ended up in the Soviet occupation zone, and the Russians began copying the German technical documentation - see for yourself that the LOMO 8x objectives are an exact copy of the objective presented here: https://www.microscopeparts.eu/?search_2=8x&search_7=ob&search_8=lomo. The objectives made for school microscopes such as the Opta Junat are also a clone of Carl Zeiss Jena optics: https://www.microscopeparts.eu/part/00639.

What is this part needed for?

• if you want to complete your Carl Zeiss Jena microscope with original parts
• if you are looking for an objective for macro photography
• if you are looking for a low magnification objective for observing objects with external light falling from the side
• if you need an 8x objective for LOMO, IOR or other compatible microscopes
• if you have a Carl Zeiss Jena microscope whose other objectives look similar and you want all the objectives in it to be "period correct"
• if you are building your own focus stacking rail (e.g. with a stepper motor)

This is description of this part:

Manufacturer logo plate to be mounted on the photo intermediate tube of Carl Zeiss Photomicroscope microscopes.

It is a brass casting with a large Carl Zeiss logo and a single line below it reading: Made in West Germany.

This is not the plate for the base of Zeiss Photomicroscope microscopes. Although it looks similar - it is not the plate for the body of the Zeiss Stereomicroscope either.

This plate has two pins on its inner side. The photo intermediate tube should have two holes into which these pins are pressed. For a firmer hold you can apply some glue to the underside of the plate.

In one of the last photos in the gallery you will see two photo-trino intermediate tubes lying side by side. As you can see, this plate is not fitted at the factory on every variant of the intermediate tube.
- I have not come across it (and I have seen no mounting holes) on the black intermediate tubes of the earliest Carl Zeiss Universal, Ultraphot and Photomicroscope models
- on the latest variants of the Photomicroscope III the logo is printed on the base (instead of a plate) and there is no plate on the intermediate tube

Importantly - intermediate tubes can be swapped between models of this class, so the surest way to tell whether this plate fits a particular tube is to check whether it has mounting holes.

Over the years this plate often fell off or was torn off, so on the second-hand market you can find microscopes with this element missing.

Some users like this style of the older models and, after cutting off the two mounting pins, they glue the plate onto a photo intermediate tube that has no mounting holes.

The last photo in the gallery shows several models of this microscope class standing side by side. Arrows mark the ones that carry a logo plate like the one offered here.

What is this part needed for?

• if you own a microscope from which such a manufacturer logo plate has fallen off and you want to complete it with original parts
• if you want to carry out a DIY modification and mount this plate on a photo intermediate tube that never had one
• if you want to place this plate somewhere else, because you are a fan of Zeiss equipment

This is description of this part:

Eyepiece tube (the so-called barrel) for mounting eyepieces of 23.2 mm diameter in Leitz Wetzlar microscope heads.

This tube was removed from the Leitz Wetzlar binocular head P/N 512582 - but tubes with exactly the same dimensions and the same mounting method are also used in other models of binocular and trinocular heads.

Two such tubes are fitted in binocular and trinocular heads - they are universal, there is no difference between the right and the left one.

The last photos in the gallery show how these tubes are screwed to the front plate of the head. The mounting screws are included with the tube offered here.

This component is often dented, and then the eyepiece can no longer be inserted. Slight deformations can easily be bent back, or the tube can be reamed out from the inside - with more serious deformations this is unfortunately not so easy. In that case, instead of replacing the whole head, it is enough to replace the eyepiece tube alone.

What is this part needed for?

• as a service part to replace a damaged tube in a head, because this tube is very often dented and the eyepiece can no longer be inserted

This is description of this part:

Iris diaphragm module - a component of PZO phase contrast microscope condensers.

An iris diaphragm of this type is fitted in the following phase contrast condensers:
- PZO K3Ph
- PZO K3Ph1
- PZO K4Ph
- PZO KS (this is the "stereo contrast" condenser sold with PZO MB30S microscopes. There are no(!) markings or numbers whatsoever on this condenser)

The diaphragm blades themselves, which are located inside this module, also fit the diaphragms installed in the following condensers:
- PZO K3PhZ (variable phase contrast)
- PZO KPI2 (condenser for Pluta DIC)

Mechanically, this diaphragm is screwed onto the lower part of the phase contrast condenser. The housing of the diaphragm module has a 32 mm male thread. The complete diaphragm with its housing has a diameter of 52 mm.

The iris diaphragm is damaged very often. Replacing it can solve the following problems:
- when the small lever used to open and close the diaphragm blades breaks off. This is a common failure, because this lever is a thin sheet made of a brittle alloy
- when the diaphragm blades get damaged, bent or broken. This is one of the most common faults in microscopes
- when the diaphragm blades jump out of their mounting grooves and you cannot reassemble them
- when the diaphragm stops opening and closing and is completely seized. This happens when the grease has dried out or rust has glued the blades together

The last photos in the gallery show the PZO KS condenser, with an arrow indicating where this diaphragm is located inside the condenser. This allows the component to be identified unambiguously.

PZO phase contrast condensers are often fitted in microscopes from manufacturers other than PZO, so the component presented here is not a repair part for one specific microscope model. This diaphragm will help to repair a phase contrast condenser - regardless of which microscope model and which manufacturer it works in.

This is description of this part:

Centring module for phase contrast annuli - a component of PZO phase contrast microscope condensers.

This module is fitted in the following phase contrast condensers:
- PZO K3Ph
- PZO K3Ph1
- PZO K4Ph
- PZO K3PhZ (variable phase contrast)
- PZO KS (this is the "stereo contrast" condenser sold with PZO MB30S microscopes. There are no(!) markings or numbers whatsoever on this condenser)

These condensers contain phase annuli (also called phase rings) and each of them can be centred. They are centred by turning two screws with rectangular heads (different from the square heads in Carl Zeiss Jena condensers).
The condenser models listed above have a special centring module screwed to the housing of the turret, with two spring-loaded centring keys that fit these screws. Thanks to this, there is no need to keep the centring keys at hand and there is no risk of losing them.

Unfortunately, these centring keys protrude more than 40 mm beyond the outline of the condenser and often get bent. In addition, many users unscrew them from the housing for transport or when they store the condenser in non-original packaging - and this leads to the unscrewed centring keys being lost frequently. The solution to such a problem is then to buy separate centring keys or to replace the entire centring module.

Mechanically, this module is screwed to the housing of the PZO phase contrast condenser with two screws, which are additionally locked by two pins - all these elements are included with the centring module presented here.

The last photos in the gallery show the PZO K3Ph condenser, with an arrow indicating where this component for centring the phase annuli is located inside the condenser. This allows the component to be identified unambiguously. The video in the video gallery shows the movement of the moving parts, the action of the springs and how the centring keys rotate.

PZO phase contrast condensers are often fitted in microscopes from manufacturers other than PZO, so the component presented here is not a repair part for one specific microscope model. This module will help to repair a phase contrast condenser - regardless of which microscope model and which manufacturer it works in.

What is this part needed for?

• as a service part for repairing a PZO phase contrast condenser
• if you have damaged or lost the centring keys used to centre the phase annuli in your phase contrast condenser

This is description of this part:

Polarising phase annulus for a 40x objective, for the PZO KS stereoscopic phase contrast condenser, compatible with PZO K3Ph, K3PhZ and other condensers.

Basic parameters of this phase annulus:
Position in the condenser: phase annulus to be fitted in the "40x" position of a turret condenser, to be paired with the phase ring in a 40x phase contrast objective
Construction: disc with a phase annulus in a mount
Material: glass, colourless polarising film and printed black circles
Diameter of the glass disc with the printed annulus: 14 mm
Disc mount: metal, with a notch for the spring-loaded ejector pin
Spring cushioning: no - the mount of the 40x phase annulus has no spring cushioning
Other names: phase disc, phase glass, phase ring
Intended for: PZO KS condenser
Compatibility: PZO K3Ph, K3Ph1, K4Ph and K3PhZ phase contrast condensers
Important note on appearance: the black dots and lines visible in the photo are not a surface defect - this is how PZO phase rings normally look
Note on the polarising film: two pieces of polarising film are glued onto the annulus. The vertical line running through the middle of the annulus is where these two films meet - it is neither a defect nor a crack, even though it looks like one

Over the years the polarising film used on these phase annuli very often came unstuck (delamination), which often - though not always - caused it to lose its properties and made stereoscopic contrast completely unusable. In such a case you can either:
- peel off the old film, clean the surface of the glass disc and glue on a new one, keeping the polarisation angle
- or replace the whole disc with one like the one offered here.

The specific feature of the PZO KS is that the ring of every disc is divided into two equal halves by two polarisers set perpendicular to each other. By rotating the analyser you extinguish one half of the ring and brighten the other - smoothly, without moving anything in the optical path. The specimen is then illuminated from one side.

And this is exactly how the disc from the KS condenser differs from the discs of the PZO K3Ph, K3Ph1, K4Ph and K3PhZ condensers. Mechanically it is the same insert, 14 mm in diameter, and it fits those condensers. The difference lies solely in the polarisation of the ring itself, described above. That is why a KS disc used in an ordinary phase condenser still gives correct phase contrast with no loss of quality, but once an analyser is placed in the optical path (for example under the head) it can produce interesting, unexpected effects.

For DIY enthusiasts looking for new, unusual visual effects in microscopy, an interesting option is to fit this polarising phase annulus into a different phase contrast condenser. You can then explore the unusual behaviour of various objectives in partially polarised light.
Here is an example: a Zernike-type phase contrast objective (PZO Ph with a green stripe) combined with the phase annulus from the PZO KS condenser gives an unusual, bluish background colour (https://www.facebook.com/photo?fbid=1262188377207557&set=a.462747092529893). And here you can see PZO microscope objectives for six types of phase contrast: https://www.facebook.com/MikroskopyPZO/photos/por%C3%B3wnanie-obiektyw%C3%B3w-pzo-20x-do-kontrastu-fazowego-pier%C5%9Bcienie-zielony-ph-kf-do/1259433520816376/.

The PZO KS condenser was fitted to PZO MB-30S microscopes and was an essential part of a special phase contrast method called "Stereoscopic Contrast" (KS). This condenser is characterised by carrying no markings at all - and that is how you recognise it.

Fastest way to recognise the PZO KS condenser:
PZO KS condenser: no serial number, no manufacturer name or logo, no model designation
Other PZO phase contrast condensers: at least a printed model designation (for example KFF, KFL, K3Ph, K3Ph1, K4Ph, K3PhZ, or KPI 2 in the case of the DIC condenser)

• as a service part for repairing the PZO KS stereoscopic phase contrast condenser, if you own one with a damaged 40x phase annulus

This is description of this part:

Carl Zeiss Jena Planachromat 12.5x microscope objective with a special kind of phase contrast for work in reflected light (EPI), intended for the Carl Zeiss Jena Neophot 21 microscope.

Basic parameters:
Manufacturer: Carl Zeiss Jena
Engraving on the objective: Planachromat 12.5x/0.25 ∞/0 Ph
Magnification: 12.5x
Numerical aperture N.A.: 0.25
Tube length: infinity (more precisely: 250 mm)
Optical correction: planachromatic
Cover glass: no - this objective is intended for work without a cover glass
Immersion: no - this is a so-called dry objective
Phase contrast: yes, a special phase contrast for work in reflected light
Polarisation: no - this is not a polarising objective
Thread: M19
Plan compensating eyepieces: yes, required - this objective needs eyepieces with additional correction (marked "PK" at Carl Zeiss Jena)
Direct projection and macro photography: no - this objective does not work in direct projection mode and is not suitable for macro photography with the objective attached directly to a camera

Phase contrast objectives for the Neophot microscopes have a phase ring built differently from the other Ph objectives made by Carl Zeiss Jena - instead of a continuous ring there is a three-segment pattern, somewhat reminiscent of a Wankel engine rotor. This is worth knowing, because it means that a phase contrast objective from a biological microscope will not replace this one in a Neophot, and the other way round.

The reason is a matter of design. In a metallurgical microscope the objective also acts as the condenser, so the illuminating light passes through the same pupil as the light forming the image. With a continuous ring the whole illumination would pass through the phase coating, which lets only part of the light through and reflects a fair amount of it - and those reflections would swamp the already faint phase contrast image. The solution turned out to be an odd number of segments: the image of the diaphragm formed after reflection off the specimen is rotated by 180 degrees, so with three segments it falls into the gaps between them. The illuminating light therefore enters beside the phase coating and returns through it. The solution is described in patent AT 295883 B.

The objective is offered together with its matching slider (Objektivwechselschlitten) with an M19 thread - and that is no coincidence. The position in which the phase sectors come to rest is decided by how far the objective screws into the thread, and every specimen stops slightly differently, which is why the factory selected objective and slider in pairs and wrote both numbers on the card in the case. Buying such a pair together avoids the whole problem - the objective already sits in relation to its slider exactly as it left the works.

Setting it up in the microscope needs neither a service technician nor a phase telescope - the Neophot has a built-in, swing-out Bertrand lens. The procedure is basically this: switch in the Bertrand lens, focus on the phase sectors and use the adjusting screws to bring the image of the sector diaphragm into coincidence with the image of the sectors in the objective; sometimes a slight rotation of the aperture diaphragm helps as well. Should the position of the glass in the sector diaphragm itself ever need correcting - it is held down by an ordinary threaded ring, so it can be turned. The whole thing resembles centring the phase rings in the condenser of a biological microscope.

Two more things are needed on the microscope side for work in phase contrast: the sector diaphragm (Sektorenblende), pushed in front of the open aperture diaphragm, and the auxiliary lens turret (Hilfslinsenrevolver) on the dovetail of the illuminator. The latter images the diaphragm exactly in the plane of the phase coating, which lies slightly differently in each objective - hence a separate auxiliary lens for every magnification. In bright field the objective of course works perfectly normally.

A note for the DIY-minded: an objective like this can be adapted for transmitted light, except that the diaphragm in the condenser is then set not opposite but in line with the segments of the objective, because there is no second pass through the pupil. Phase contrast should appear, but with stronger halo and a directional relief effect, since the gaps in the ring mean that part of the illumination azimuths is missing. On top of that comes the infinity design with no cover glass correction, so a tube lens will be needed. More of an experiment than a working solution - but doable in one evening.

The last photos in the gallery show:

* a photo of the original table indicating which serial numbers of the objective sliders are factory-paired with which serial numbers of the objectives
* two pages of errata to the instruction manual of the Carl Zeiss Jena Neophot 2 microscope.

The "compatibility" section lists, besides the Carl Zeiss Jena Neophot 21 microscope, those microscopes that this objective fits mechanically and optically. What result you get on them, however, can sometimes be a surprise.

Here (https://www.microscopeparts.eu/part/91056) you can read more about using Carl Zeiss Jena objectives with an M19 thread.

What is this part needed for?

• if you own a Carl Zeiss Jena Neophot 21 microscope with phase contrast but are missing the 12.5x objective from the set
• if you own the complete set but your 12.5x objective is damaged or in very poor condition
• if you like to be prepared and want such an objective in reserve, as it rarely turns up on the second-hand market
• if you are putting together a phase contrast set of this kind yourself and sourcing every part separately
• if you need an objective of this magnification for one of the microscopes it works with (further details are given in the description)

Phase contrast: yes, a special phase contrast for work in reflected light
Polarisation: no - this is not a polarising objective
Thread: M19
Plan compensating eyepieces: yes, required - this objective needs eyepieces with additional correction (marked "PK" at Carl Zeiss Jena)
Direct projection and macro photography: no - this objective does not work in direct projection mode and is not suitable for macro photography with the objective attached directly to a camera

Phase contrast objectives for the Neophot microscopes have a phase ring built differently from the other Ph objectives made by Carl Zeiss Jena - instead of a continuous ring there is a three-segment pattern, somewhat reminiscent of a Wankel engine rotor. This is worth knowing, because it means that a phase contrast objective from a biological microscope will not replace this one in a Neophot, and the other way round.

The reason is a matter of design. In a metallurgical microscope the objective also acts as the condenser, so the illuminating light passes through the same pupil as the light forming the image. With a continuous ring the whole illumination would pass through the phase coating, which lets only part of the light through and reflects a fair amount of it - and those reflections would swamp the already faint phase contrast image. The solution turned out to be an odd number of segments: the image of the diaphragm formed after reflection off the specimen is rotated by 180 degrees, so with three segments it falls into the gaps between them. The illuminating light therefore enters beside the phase coating and returns through it. The solution is described in patent AT 295883 B.

The objective is offered together with its matching slider (Objektivwechselschlitten) with an M19 thread - and that is no coincidence. The position in which the phase sectors come to rest is decided by how far the objective screws into the thread, and every specimen stops slightly differently, which is why the factory selected objective and slider in pairs and wrote both numbers on the card in the case. Buying such a pair together avoids the whole problem - the objective already sits in relation to its slider exactly as it left the works.

Setting it up in the microscope needs neither a service technician nor a phase telescope - the Neophot has a built-in, swing-out Bertrand lens. The procedure is basically this: switch in the Bertrand lens, focus on the phase sectors and use the adjusting screws to bring the image of the sector diaphragm into coincidence with the image of the sectors in the objective; sometimes a slight rotation of the aperture diaphragm helps as well. Should the position of the glass in the sector diaphragm itself ever need correcting - it is held down by an ordinary threaded ring, so it can be turned. The whole thing resembles centring the phase rings in the condenser of a biological microscope.

Two more things are needed on the microscope side for work in phase contrast: the sector diaphragm (Sektorenblende), pushed in front of the open aperture diaphragm, and the auxiliary lens turret (Hilfslinsenrevolver) on the dovetail of the illuminator. The latter images the diaphragm exactly in the plane of the phase coating, which lies slightly differently in each objective - hence a separate auxiliary lens for every magnification. In bright field the objective of course works perfectly normally.

A note for the DIY-minded: an objective like this can be adapted for transmitted light, except that the diaphragm in the condenser is then set not opposite but in line with the segments of the objective, because there is no second pass through the pupil. Phase contrast should appear, but with stronger halo and a directional relief effect, since the gaps in the ring mean that part of the illumination azimuths is missing. On top of that comes the infinity design with no cover glass correction, so a tube lens will be needed. More of an experiment than a working solution - but doable in one evening.

The last photos in the gallery show:

* a photo of the original table indicating which serial numbers of the objective sliders are factory-paired with which serial numbers of the objectives
* two pages of errata to the instruction manual of the Carl Zeiss Jena Neophot 2 microscope.

The "compatibility" section lists, besides the Carl Zeiss Jena Neophot 21 microscope, those microscopes that this objective fits mechanically and optically. What result you get on them, however, can sometimes be a surprise.

Here (https://www.microscopeparts.eu/part/91056) you can read more about using Carl Zeiss Jena objectives with an M19 thread.

What is this part needed for?

• if you own a Carl Zeiss Jena Neophot 21 microscope with phase contrast but are missing the 6.3x objective from the set
• if you own the complete set but your 6.3x objective is damaged or in very poor condition
• if you like to be prepared and want such an objective in reserve, as it rarely turns up on the second-hand market
• if you are putting together a phase contrast set of this kind yourself and sourcing every part separately
• if you need an objective of this magnification for one of the microscopes it works with (further details are given in the description)

This is description of this part:

Focus knob for the coarse focusing holder of the Japanese Nissho Optical 209 stereo microscope.

Basic parameters of this knob
Outer diameter of the knob: 45 mm
Diameter of the knob on the focusing holder side: 28 mm
Mounting on the pinion shaft: the knob has a threaded hole into which the pinion shaft is screwed, as the shaft is threaded at both ends. Once screwed in, the shaft is additionally secured with two screws
Threaded hole diameter: 5 mm

It is very likely that Nissho Optical (NSK for short) uses identical knobs across its whole range of stereo microscopes, or more precisely: in the head holders of those microscopes. I give the dimensions of this knob in the parameter block so that you can check compatibility if you are looking for a knob for a model other than the "209".

The focusing holder of a stereo microscope contains two such knobs. Both are identical, so there is no difference between the right-hand and the left-hand knob. I offer each of these knobs separately, as a single item.

The last photo shows the coarse focusing holder of the Nissho Optical 209 stereo microscope, with an arrow pointing out which knobs are meant and where they are located.

What is this part needed for?

• as a service part, if you need to replace a damaged knob
• if you own a Nissho Optical 209 stereo microscope but a knob is missing from the focusing holder
• if you have checked the knob dimensions and want to fit it to a different Nissho Optical stereo microscope

Central prism for the Leitz Wetzlar microscope head. This is the central beamsplitter prism.

This prism was removed from a Leitz Wetzlar binocular head P/N 512582 - but exactly the same prisms are also used in other models of binocular and trinocular heads.

It is neither the right nor the left eyepiece prism. It is the central prism that splits the beam towards the right and the left eye.

The last photo in the gallery shows a disassembled Leitz Wetzlar 512582 binocular head, with an arrow pointing to the prism in question and to its position inside the head. This makes the part easy to identify.

Replacing this prism in a Leitz Wetzlar microscope head can be the remedy for the following problems:
- if the prism in your head is mechanically damaged: it may be cracked or chipped
- if the prism to be replaced has a damaged anti-reflective coating: this may be caused by fungus, or the coating may be scratched by improper cleaning
- if discolouration or separation (delamination) is visible inside the prism. This is a cemented prism, and over the years the cement can discolour or come apart in places, which is unfortunately visible in the field of view while working with the microscope
- if the reflective layer inside the prism (usually silver) oxidises and loses its properties in places or completely

Before you decide to use this prism in a Leitz Wetzlar head other than model 512582, first compare the exact dimensions (a millimetre scale is visible in the photos) and, if in doubt, ask on internet groups and forums.

What is this part needed for?

Microscope objective with 10x magnification for MOTIC microscopes.

Basic parameters of this objective:
Manufacturer: MOTIC
Engraving on the barrel: 10/0.25 160/0.17
Magnification: 10x
Numerical aperture N.A.: 0.25
Tube length: 160 mm
Parfocal length: 45 mm
Cover glass: according to the engraving on the barrel 0.17 mm, but with 10x objectives a cover glass is in practice not required - the objective works both with and without one
Immersion: no (this is a dry objective)
Thread: RMS

I have personally tested this objective with the following microscopes:
- MOTIC B1
- MOTIC SFC-100
- PZO Studar
- Carl Zeiss Jena Ergaval
- Olympus CH

This MOTIC microscope objective will work well in a microscope from any manufacturer, provided it has an RMS thread, optics corrected for a 160 mm tube length and accepts objectives with a 45 mm parfocal length. As for the parfocal length: in the vast majority of cases (almost always) objectives with a 45 mm parfocal length can also be fitted to microscopes originally sold with so-called short barrel objectives, that is with a 33 mm or 37 mm parfocal length. In such a case it is more convenient not to mix the objectives and to have them all of the same length - but that is only a matter of convenience, not a requirement. In the compatibility section I do not list microscopes from other manufacturers, because that list would need several hundred entries.

This also works the other way round: in the MOTIC B1 and MOTIC SFC-100 microscopes you can use any objective with an RMS thread, corrected for a 160 mm tube length and with a 45 mm parfocal length - from any manufacturer. These can be unbranded objectives, PZO or Carl Zeiss Jena objectives - but the objective offered here will please those who own a MOTIC microscope and want to complete it with original parts.

What is this part needed for?

• if you own a compatible MOTIC microscope, are missing the 10x objective for it - and want to complete it with original parts
• if you want to use this objective in any other compatible microscope

Eyepiece tube with a 23.2 mm eyepiece seat for a microscope binocular head by Carl Zeiss (Oberkochen, West Germany).

This is the tube with the diopter adjustment ring fitted, which compensates for the refractive error of one eye and lets you focus the image correctly. The tube without diopter adjustment is here: https://www.microscopeparts.eu/part/91069.

Basic parameters:
- Type: tube with diopter adjustment ring
- Diameter of eyepieces accepted: 23.2 mm
- Color: black

This tube fits the binocular heads:
- Zeiss 473016 (also written: 47 30 16-9901)
- Zeiss 473012 (also written: 47 30 12-9901)
- Zeiss 473011 (also written: 47 30 11-9901)
- Zeiss 473013 (also written: 47 30 13-9901)
and probably others, as Zeiss often used the same components in several head models.

Before fitting this tube into your own head you should above all:
- check the shape of the tube foot. For example, there is also a polarizing variant of the head, Zeiss 47 30 12-9902, in which the eyepiece tube seat has a different shape (you can see it here: https://www.microscopeparts.eu/part/00536)
- check how many screws hold it to the head
- check all the dimensions (the photos show a millimeter scale)

This is a service part for a microscope binocular head - not for one particular microscope model. Such a head can be mounted on many Zeiss microscope models (and even on microscopes from other makers), so no list of microscopes this tube fits can be given - it fits the head, and the user mounts the head wherever they want.

In the last photo, an arrow shows where this element is located inside the head, allowing precise identification.

What is this part needed for?

• very often this tube is dented and an eyepiece cannot be inserted
• very often the diopter adjustment ring becomes damaged and does not function
• if you want diopter adjustment on both eyepiece tubes and replace the simple tube with one equipped with an adjustment ring
• if you need a tube with precise worm adjustment for your own DIY purposes

- check the shape of the tube foot. For example, there is also a polarizing variant of the head, Zeiss 47 30 12-9902, in which the eyepiece tube seat has a different shape (you can see it here: https://www.microscopeparts.eu/part/00536)
- check how many screws hold it to the head
- check all the dimensions (the photos show a millimeter scale)
- and of course check that the mounting diameter of your eyepieces is 23.2 mm

This is a service part for a microscope binocular head - not for one particular microscope model. Such a head can be mounted on many Zeiss microscope models (and even on microscopes from other makers), so no list of microscopes this tube fits can be given - it fits the head, and the user mounts the head wherever they want.

The last photo has an arrow showing where this part sits in the head, so you can identify it without any doubt.

What is this part needed for?

• very often this tube is dented and an eyepiece cannot be inserted

Complete Siedentopf type interpupillary distance adjustment mechanism for the Leitz Wetzlar 512582 microscope binocular head and similar heads.

This is the front part of the microscope binocular head - the part into which the eyepiece tubes are screwed.

This mechanism was removed from a Leitz Wetzlar binocular head P/N 512582 - but exactly the same one is also used in other models of binocular and trinocular heads.

Before you use this mechanism (or one of its smaller components) in a Leitz Wetzlar head other than model 512582, first compare the exact dimensions - a millimetre scale is visible in the photos - and if in doubt, ask on internet groups and forums.

Original aluminium nameplate with the model designation for the Carl Zeiss Jena Jenamed hematology microscope.

Parameters of this nameplate:
Manufacturer: Carl Zeiss Jena
Lettering: Jenamed hematology
Material: aluminium
Length: 65 mm
Width: 12 mm
Mounting: the plate is glued on

By default, such a plate was fitted to every Carl Zeiss Jena Jenamed microscope in the "hematology" version. Since the adhesive used to attach these plates to the microscope body loses its properties over the years, these plates very often fall off.

Such a plate lets you bring your microscope back to its factory appearance using original parts.

• if the original model nameplate has fallen off your Carl Zeiss Jena Jenamed hematology microscope
• if you simply like this plate and want to have one
• if you feel like putting such a plate on your microscope from another manufacturer

Main objective f=125 for the Carl Zeiss slit lamps 125/16 and 100/16.

This objective fits the following slit lamp microscopes:
- Carl Zeiss Slit Lamp 125/16
- Carl Zeiss Slit Lamp 100/16

I have not found any documentation confirming my assumption, but most probably this objective also fits the models:
- Carl Zeiss Slit Lamp 20 SL
- Carl Zeiss Slit Lamp 30 SL

Important: it is widely but wrongly believed that these slit lamp models have a built-in objective with a magnification changer. That magnification changer is not an objective. It is a Galilean lens system, while the objective itself screws onto a thread underneath the body of this microscope.

A note on the mounting thread diameter: this f=125 objective has a mounting thread of 47 mm diameter. Slit lamps are not surgical microscopes, even though they are sometimes - incorrectly - called Zeiss OPMI f=125. The early models of the Zeiss OPMI surgical microscopes have objectives with a mounting thread of 48 mm diameter. This single millimetre of difference is why objectives from these two kinds of microscopes are often confused, especially as they can almost be screwed into a female thread 1 mm larger or smaller in diameter.

Several terms are used for this slit lamp microscope (slit lamp):
- Carl Zeiss Spaltlampe 125/16
- Carl Zeiss Spaltlampe f=125
- Carl Zeiss Slit Lamp f=125
- Carl Zeiss Slit Lamp 125/16
- Carl Zeiss OPMI f=125 (although this name is incorrect)
- Carl Zeiss f=125 head
- Carl Zeiss f-125 slit lamp microscope
- Carl Zeiss f-125 slit lamp
- Carl Zeiss f-125 stereo microscope
[[//BLOK]]

What is this part needed for?

• if you own a Carl Zeiss Slit Lamp F 125 without an objective (because someone unscrewed it, for example) or with a damaged one
• if you own a Carl Zeiss Slit Lamp F 100 without an objective or with a damaged objective
• if you own a Carl Zeiss Slit Lamp F 100 with the objective standard for that model (that is f=100) and you want to increase its working distance to 125 mm

Original square blue nameplate with the manufacturer logo for the Zeiss microscope.

Parameters of this nameplate:
Manufacturer: Zeiss
Lettering: silver "Zeiss" logotype in the typeface used since the London Agreement of 1971
Material: plastic
Colour: the so-called "early light blue", used by the manufacturer until 1997
Dimensions: 27 mm x 27 mm
Mounting: the plate is glued on

This is an interesting variant of the logo plate. The square logo, introduced at the end of the 1970s, carried the lettering "West Germany" in its second line. The plate shown here does not have that lettering. It may well be a version produced after German reunification (1990) and before the new version of the logotype was introduced (1993/94).

Since the adhesive used to attach these plates to the microscope body loses its properties over the years, these plates sometimes fall off. Sometimes they are also deliberately prised out. Such a plate lets you bring your microscope back to its factory appearance using original parts.

What is this part needed for?

• if the original manufacturer logo nameplate has fallen off your Carl Zeiss microscope
• if you simply like this plate and want to have one

Carl Zeiss Photomicroscope III RS power supply cable with 12 pin plug, 2x6 flat contacts, from microscope base

This is one of two cables coming out of the base of the Zeiss Photomicroscope III microscope. The following cables come out of it:
- with a 12 pin plug (2x6)
- with a 22 pin plug (2x10 + 2)

The cable presented here ends with a 12 pin plug, that is 6 rows of two flat contacts each. Marking on the plug: "Siemens DIN41622 VG95322 A12".

The cable was tested before being removed from a working microscope. The plug is fully functional, its plastic housing is neither broken nor crumbled, and all contacts are straight. Attaching / soldering on the base side has to be taken care of on your own.

Several names are used for this microscope model, among others:
- Carl Zeiss Photomicroscope III
- Carl Zeiss Phomi III
- Carl Zeiss PM III
- Zeiss Photomicroscope III RS
- Zeiss Phomi 3
- Zeiss PM3 RS

Replacing this cable can solve, among others, the following problems:
- when the microscope has a cut off cable, which is common when it comes from an institution that scraps electrical equipment this way
- when the microscope has a cable with a plug whose housing is broken, cracked or chipped
- when the microscope has a cable ending in a plug with broken off flat contacts
- when the microscope has a cable in which the plug has a damaged latch

A new plug of this type can be bought today. It is the DIN 41622 standard, a two row arrangement of 3.0 x 1 mm blade contacts, 12 poles - produced continuously for decades and offered today by Telegärtner, Binder, MPE and EVG among others. At Telegärtner the 12 pole male connector carries the number 100023261, and the matching female connector the number 100023250. One has to keep in mind, however, that this is only the contact insert itself: the cable housing (metal or plastic) together with the mounting trough is bought separately, the guide pins that also serve as coding are bought separately, the cable of the right cross section is bought separately, and all twelve contacts have to be soldered. Some users will appreciate owning an original cable with a period plug whose coding matches their microscope, while others will be glad that I have given the designations of the new equivalents and can go their own way.

What is this part needed for?

• if you own a microscope without this cable, or with a damaged cable or plug
• a list of several cases in which replacing the cable may be necessary can be found in the description

Cable supplying the exposure automation, to the power supply, with 22 pin plug, 2x10 + 2 flat contacts, from the base of the Carl Zeiss Photomicroscope III microscope

This is one of two cables coming out of the base of the Zeiss Photomicroscope III microscope. The following cables come out of it:
- with a 12 pin plug (2x6)
- with a 22 pin plug (2x10 + 2)

The cable presented here ends with a 22 pin plug, that is 10 rows of two flat contacts each plus two single contacts in the middle. In the Zeiss manual the matching socket on the power supply is described as a 22 pole socket for the supply voltages of the automatic exposure control. There is no standard designation on the plug - only the marking "Siemens" and the letter "R" are visible.

The cable was tested before being removed from a working microscope. The plug is fully functional, its plastic housing is neither broken nor crumbled, and all contacts are straight. Attaching / soldering on the base side has to be taken care of on your own.

Several names are used for this microscope model, among others:

- when the microscope has a cable with a plug whose housing is broken, cracked or chipped
- when the microscope has a cable ending in a plug with broken off flat contacts
- when the microscope has a cable in which the plug has a damaged latch

I have not found a new 22 pole plug in the current catalogues of the makers of this blade connector family - this pole count falls outside the range produced today. What remains is the second hand market. An original, working cable with a period plug saves you that search.

Aplanatic low numerical aperture condenser for the Carl Zeiss Jena Jenaval microscope.

Carl Zeiss Jena Jenaval and Jenalumar microscopes each have two condensers - a low-power survey condenser with low numerical aperture and a main condenser with high aperture. Both sit on a common carrier at the same time, which lets you switch between them. What I am offering here is the condenser alone, so without the carrier.

Parameters of this condenser:
Manufacturer: Carl Zeiss Jena
Numerical aperture N.A.: 0.12
Correction: aplanatic
Mounting: the condenser screws into a dedicated carrier. The thread diameter is 36 mm.
Iris diaphragm: yes, the condenser has a ring that opens and closes the diaphragm
Removable top lens: no
Intended use: this condenser model was fitted in Carl Zeiss Jena Jenaval microscopes

This condenser can also be screwed into the carrier of Carl Zeiss Jena Jenalumar microscopes - it is the same carrier as in Jenaval microscopes. Note, however, that Jenalumar microscopes came with a 0.20 N.A. condenser as standard (you can see it here: https://www.microscopeparts.eu/part/00530).

A condenser with such a low numerical aperture is intended for observation with low magnification microscope objectives (1.25x / 3.2x / 6.3x, 10x at most).

What is this part needed for?

• if this condenser is missing from your Carl Zeiss Jena Jenaval microscope, because someone unscrewed it, for example
• if you have a microscope with this condenser but it is damaged - the diaphragm blades are bent or broken, for instance
• if you have a Carl Zeiss Jena Jenalumar microscope and deliberately want to fit a 0.12 N.A. condenser in it
• if you want to use this condenser as the only condenser in a different microscope and mount it there with your own DIY holder

Achromatic-aplanatic dry condenser 0.9 for the Carl Zeiss Jena Jenaval microscope.

Carl Zeiss Jena Jenaval and Jenalumar microscopes each have two condensers - a survey condenser with low numerical aperture and a main condenser with high aperture. Both sit on a common carrier at the same time, which lets you switch between them. What I am showing here is the main one, with the 0.9 aperture - the condenser alone, so without the carrier.

Parameters of this condenser:
Manufacturer: Carl Zeiss Jena
Numerical aperture N.A.: 0.9
Correction: achromatic-aplanatic (Achr. apl.)
Immersion: no. This is a dry condenser
Mounting: the condenser carrier holds a centrable threaded ring, and the condenser screws into that ring. The thread diameter is 38 mm.
Iris diaphragm: not on the condenser - the diaphragm sits in the carrier, below the condenser
Intended use: this condenser model was fitted in Carl Zeiss Jena Jenaval microscopes

How it mounts in the carrier:
- The condenser carrier holds a threaded ring, and the ring itself is centrable - two centring screws do that job (these ones: https://www.microscopeparts.eu/part/00535).
- The screws set the position of the ring, and the condenser simply screws into that ring.
- Further down, in the same carrier, sits the iris diaphragm for this main condenser. It is centrable as well and has its own screws for that.

This condenser can also be screwed into the carrier of Carl Zeiss Jena Jenalumar microscopes - it is the same carrier as in Jenaval microscopes. Note, however, that Jenalumar microscopes run the Apl. 0.9 condenser from the factory, that is the aplanatic version without achromatic correction.

The Achr. apl. 0.9 condenser is the working condenser of these microscopes - it covers the whole range of dry objectives, but with immersion objectives it works without making use of their full aperture.

What is this part needed for?

• if this condenser is missing from your Carl Zeiss Jena Jenaval microscope, because someone unscrewed it, for example
• if you have a microscope with this condenser but it is damaged - with a damaged top lens, for instance, which is very common
• if you have a Carl Zeiss Jena Jenalumar microscope and deliberately want to fit an achromatic-aplanatic condenser in it
• if you want to use this condenser as the only condenser in a different microscope and mount it there with your own DIY holder

- Carl Zeiss Jena Jenalumar
- Carl Zeiss Jena Jenapol
- Carl Zeiss Jena Jenavert

The so-called "small illuminators", that is the halogen 25W one (like this: https://www.microscopeparts.eu/gallery/99693) or the HBO 50W, are held by two such screws. Large HBO 250W illuminators with an integrated power supply are mounted on 4 such screws.

If your microscope has only one small illuminator (for example a Jenaval with transmitted light or a Jenavert with EPI illumination), you can extend it with a second (also small) illuminator. You will then need two screws for that.

What is unusual (and sometimes the reason why a user cannot find these screws for a long time) is that they are unscrewed FROM THE FRONT of the microscope. The heads of these screws sit in openings cut into the white sheet-metal side covers of the microscope. You can see these covers with the screw openings here: https://www.microscopeparts.eu/gallery/99692.

What is this part needed for?

• if such a screw is missing, has bent, broken off or been lost
• if you are extending your microscope with a second illuminator and have no mounting screws for it

This is description of this part:

Photo tube / camera adapter Carl Zeiss Jena - also fitting microscopes of other makers: LOMO, Meopta, Olympus, IOR or Gamma.

The tube allows you to connect a camera to a trinocular head or directly to the microscope stand, even when there is no trinocular head at all.

This is a black tube with an upper element (barrel) 55 mm long. Here (https://www.microscopeparts.eu/gallery/91057) you can see a functionally identical adapter, but grey and with an upper barrel only 25 mm long.

Black adapters of this kind come from the era of the Carl Zeiss Jena L stands (models Carl Zeiss Jena Lg, Lumipan, Ng, Nf or Nu). The grey ones are newer, from the era of the Mikroval series (models Carl Zeiss Jena Laboval, Eduval, Ergaval or Amplival and Docuval).

The mounting fit is of course identical, so both can be used interchangeably.

Basic technical parameters of this tube:
Manufacturer: Carl Zeiss Jena
Colour: black
Inclination angle: none, this is a straight tube
Internal optics: none - not even a deflecting prism
Mounting to a trinocular head or microscope stand: ring dovetail
Ring dovetail diameter: 41.5 mm
Type of connection at the output: empty barrel / tube
Tube diameter at the output: 23.2 mm inner diameter
Barrel / tube length: 55 mm
Tube length adjustment: no - this is not a height-adjustable tube

Because on the output side this adapter has an empty barrel with an inner diameter of 23.2 mm, you can place in it a projection eyepiece of that diameter or a so-called USB eyepiece, that is a digital microscope camera. In addition, adapters between the 23.2 mm barrel and the M42 thread are widely available, and from the M42 thread you can already move on to any other mount: Nikon, Canon, Sony and all the rest.

Such a tube can be mounted directly on the microscope stand, in place of the head. A seat for a ring dovetail of 41.0 - 41.5 mm diameter is found among others in the microscopes:
- Carl Zeiss Jena
- LOMO
- Meopta
- IOR
- Reichert Biopan
- Olympus CH
- Gamma

It is also used in microscopes with a slightly larger seat, among others Zeiss West Germany, Leitz Wetzlar, PZO, Will Wetzlar, Hund Wetzlar.

The adapter can likewise be fitted onto trinocular heads, as many of them have a seat prepared for it, among others:
- the output in the trinocular tubes of the microscopes Carl Zeiss Jena Jenamed, Jenaval, Jenalumar, Jenatech, Jenavert, Jenapol
- the LOMO TRN-1 heads (ЛОМО ТРН-1), found in LOMO Polam microscopes
- some versions of the black intermediate photo tubes for the microscopes Carl Zeiss Jena Lg / Lumipan / Nf and of the grey ones from the Mikroval series (others require a tube that screws in on a thread)

This is not a tube for one particular microscope model. A trinocular head can be mounted not only on the microscope it was sold with, so the correct assumption is that this is a universal tube with a ring dovetail of 41.5 mm diameter on one side and a barrel of 23.2 mm diameter on the other.

In the compatibility section you will find an example list of microscopes this tube fits, although that list is not complete.

What is this part needed for?

• if you need a tube that allows a camera or photographic camera to be connected to a trinocular head
• if you need to connect a camera or photographic camera directly to the microscope body

This is description of this part:

A photo tube that allows a projection eyepiece to be mounted on the trinocular head of Leitz Wetzlar microscopes.

Photo / trino heads for Leitz Wetzlar microscopes have a standardized mount of 38 mm diameter into which various tubes can be fitted. One of exactly these tubes is presented here.

Basic parameters of the tube presented here:
Markings on the housing: "Germany" on one side and "30ø" on the other side
Mounting connection: a plain tube (cylinder). This is not a tube with a thread or a dovetail
Mounting diameter: 38 mm, that is the standard mounting diameter used in Leitz Wetzlar trinocular heads
Internal optics: none - this tube has no optics inside
Internal diameter: the tube has an internal diameter of 30 mm, so that a projection eyepiece of exactly that diameter can be fitted inside

The trinocular heads this tube fits are used among others in the following microscopes:
- Leitz Wetzlar Orthoplan
- Leitz Wetzlar Diaplan
- Leitz Wetzlar Ergolux
- Leitz Wetzlar Dialux
- Leitz Wetzlar Laborlux
- Leitz Wetzlar SM-LUX
- Leitz Wetzlar Ortholux II
- Leitz Wetzlar Aristoplan
- Leitz Wetzlar HM-LUX

This is not a tube for one particular microscope model. A trino head can be mounted not only on the microscope it was sold with, so the correct assumption is that this is a standard tube for Leitz Wetzlar trinocular heads - and those can be used on most microscope models of this company.

The last photo in the gallery shows what this tube looks like with a 30 mm eyepiece fitted.

The "compatibility" section lists example microscopes this tube fits, although the list is not complete.

Mounting screw for the photo tube / camera tube in the trino port of the Nikon SMZ-10 stereo microscope.

The trino version of the Nikon SMZ-10 stereo microscope has a modular photo output. Into the integrated, universal part of the trinocular you insert a tube ending with whatever mount you need. And this is exactly the original screw that holds that optional tube in place.

It is not a screw of any exceptional shape, but many users value having an original part.

This is description of this part:

An original aluminium nameplate with the manufacturer logo for Carl Zeiss Jena microscopes.

Parameters of this nameplate:
Manufacturer: Carl Zeiss Jena
Inscription: logo "Carl Zeiss Jena" and text "Q1 MADE IN DDR"
Material: aluminium
Length: 52 mm
Width: 14 mm
Mounting: the nameplate is glued on

By default such a nameplate was fitted to most Carl Zeiss Jena microscopes from the Mikroval series onwards. There is also a smaller nameplate - with the manufacturer logo only (without the "Q1 Made in DDR" text). You can see it here: https://www.microscopeparts.eu/part/00604.

Because the adhesive used to attach these plates to the microscope body loses its properties over the years, these plates very often fall off. A nameplate like this makes it possible to restore the factory appearance of a microscope using original parts.

What is this part needed for?

• if the original manufacturer nameplate has fallen off your Carl Zeiss Jena microscope
• if you simply like this plate and want to have one
• if you feel like putting such a plate on your microscope from another manufacturer

- the secondary objective
- the inclining prism
- the erecting prism
- the eyepiece

Offered here is the inclining prism for the right optical path. The prism sits in its matching cradle (holder) made of cast metal.

The last three photos in the gallery are drawings from the service manual of the Nikon SMZ-10 microscope, and an arrow on them marks which element this is and where it sits in the head of the stereo microscope.

Replacing the inclining prism in the stereo head of the Nikon SMZ-10 microscope can help when:
- the prism has mechanical damage, e.g. scratches, cracks, chips or flaking
- the silver reflective coating inside the prism has oxidised and lost its properties
- the metal cradle holding the prism is broken

Holder for the left inclining prism from the head of the Nikon SMZ-10 stereo microscope.

In the Nikon SMZ-10 stereo microscope each of the two optical paths (one per eye) consists of:
- the zoom lens group
- the secondary objective
- the inclining prism
- the erecting prism
- the eyepiece

Each prism sits in its matching cradle (holder) made of cast metal. The manufacturer calls this holder a "prism seat". Offered here is the holder (seat) for the left inclining prism.

Replacing this inclining prism holder in the stereo head of the Nikon SMZ-10 microscope can help when the metal cradle holding the prism is broken. The cradle is made of a relatively brittle alloy and such damage is unfortunately not uncommon.

Such a broken seat, or a prism fitted without its seat - makes it impossible to set the correct collimation of the image and can lead to damage of the prism.

Cover of the left erecting prism from the head of the Nikon SMZ-10 stereo microscope.

This is the part of the head the user grips to change the interpupillary distance. It protects access to the left erecting prism and at the same time the eyepiece tube passes through it - part of the tube sits under this cover, part of it sits outside.

The manufacturer calls this element a "prism box".

The last photos in the gallery have an arrow marking which element this is and where it sits in the head of the stereo microscope. This allows unambiguous identification.

Replacing this prism lid in the stereo head of the Nikon SMZ-10 microscope may turn out to be necessary when the cover has mechanical damage, e.g. deep scratches that cannot be painted over, cracks, chips or flaking.

This is description of this part:

Round dovetail mount of the head of the Nikon SMZ-10 stereo microscope.

This is the part of the head that sits on its underside and by which the head is mounted to the microscope body.

This round dovetail has a diameter of 60 mm.
The mount has two openings - one for each optical path. There is no optics in the openings - they are simply "empty holes" and this is their factory condition. It is true that in some stereo microscope heads the secondary objectives sit in the dovetail itself (for example in the PZO MST-130 microscope) - but in the Nikon SMZ-10 microscopes they sit on a separate element located deeper inside the head.

The last photo in the gallery has an arrow marking which element this is and where it sits in the head of the stereo microscope. This allows unambiguous identification.

This mount can be successfully used for your own DIY projects, to fit it into a different head and adapt that head to the Nikon 60 mm standard.

What is this part needed for?

• if the mounting dovetail is missing from the head of your Nikon SMZ-10 stereo microscope or is, for example, chipped
• if you want to use an original Nikon 60 mm dovetail mount for your own DIY project

This is description of this part:

Tube for mounting a photo eyepiece in the trinocular port of the Nikon SMZ-10 stereo microscope.

The Nikon SMZ-10 stereo microscope in the trinocular version has a modular photo output. Inside the fixed part of the trinocular, which is integrated with the head housing, sits a tube into which a photo eyepiece can be inserted. The manufacturer calls this element a "photographic lens holder".

Since the inner diameter of this tube is 23.2 mm, it takes the Nikon CF PL2.5X, Nikon PLI 5 and other photo eyepieces with this standard mounting diameter.

Inside this tube there is a helicoid mechanism for adjusting parfocality, so the sharpness of the image on the sensor of a camera can be tuned precisely.

The last three photos in the gallery have an arrow marking which element this is and where exactly it sits in the head of the stereo microscope. This allows unambiguous identification.

What is this part needed for?

• if this element is missing or damaged in the trinocular port of your Nikon SMZ-10 stereo microscope
• if you need a precise helicoid mechanism for your own DIY project

This is description of this part:

Top housing part (cover) of the microscope trinocular head Olympus U-TR30 / U-TR30-2

The Olympus U-TR30 / U-TR30-2 photo-trinocular heads are most often used in the following microscopes:
- Olympus CX30 / CX31
- Olympus CX40 / CX41 / CX43
- Olympus BX40 / BX41 / BX43
- Olympus BX50 / BX51 / BX53
- Olympus BX60 / BX61
- and probably others

This is a black housing made of cast metal. Metal, cast or injection-molded parts of Olympus carry their own numbers. This microscope element bears the number AB8931.

Because this is a brittle casting, the housing can crumble, crack or break. The remedy is then to replace the complete head or just this part of the housing.

In the compatibility section you will find an example list of microscopes the U-TR30 fits, although that list is not complete.

What is this part needed for?

• as a service item in the form of replacing the entire element when the housing in your head is in very poor condition or, for example, has cracked

This is description of this part:

A female dovetail mount with a 42 mm internal diameter, for fitting the photo tube into the trinocular heads of Olympus microscopes.

This particular mount was removed from an Olympus U-TR30 trinocular head.

The Olympus U-TR30 / U-TR30-2 photo-trinocular heads are most often used in the following microscopes:
- Olympus CX30 / CX31
- Olympus CX40 / CX41 / CX43
- Olympus BX40 / BX41 / BX43
- Olympus BX50 / BX51 / BX53
- Olympus BX60 / BX61
- Olympus MX40 / MX50
- and probably others

Olympus offers a whole range of tubes with a 42.1 mm mounting diameter, so such mounts are fitted not only to the U-TR30 head.

The female mount for adapters with a 42 mm dovetail (more precisely, according to the manufacturer specification: 42.1 mm) is found, among others, on the following microscope heads and tubes:
- Olympus U-TR30
- Olympus U-TR30-2
- Olympus U-TR30H
- Olympus U-TR30IR
- Olympus U-TR30NIR
- Olympus U-TTR-2
- Olympus U-ETR3
- Olympus U-ETR30
- Olympus U-ETR-4
- Olympus U-SWTR
- Olympus U-SWTR-2
- Olympus U-SWTR-3
- Olympus U-SWETR
- Olympus U-SWETTR-2
- Olympus U-SWETTR-5
- Olympus MX-SWETTR
- Olympus U-CTR30-2
- Olympus U-TRU
- Olympus U-TRUS
- Olympus U-MPH
- Olympus U-TLU
- Olympus SZX-TR30
- Olympus SZX2-TTR
- Olympus SZX2-TTRPT
- and probably others

Important: as of now (2026) the microscope brand "Olympus" has been replaced by "Evident". Evident microscopes (e.g. Evident BX53) still keep the previous standard, so the 42mm mount is also found in products carrying that brand.

Metal, cast or injection-molded parts of Olympus carry their own numbers. This microscope element bears the number AB8980.

Because this is a brittle casting, the mount can crumble, crack or break. The remedy is then to replace the complete head or just this part - fortunately this mount is a separate component, fixed to the head with three screws.

And this implies another important matter: the diameter of the mount is standard, but I cannot guarantee that a mount fixed with exactly three screws fits every one of those heads and tubes, and even if it does - whether their hole spacing is the same in each of those models. The user should check that for himself based on the photos in the gallery.

Where the descriptions quoting a 51 mm diameter come from?
On the website of "Martin Microscope" and in many other descriptions available online, exactly the same (sic!) mount is described as having a diameter of 51 mm. That is the internal diameter of the ring, measured without the seat of the dovetail taper. So the 51 mm at "Martin Microscope" refers to the same mount into which a 42 mm dovetail is inserted.

This is not a part for one specific microscope model. As listed above - such a mount can be found in many heads and tubes, and these in turn in any microscope the user fits them into.

In the "compatibility" section there is an example list of microscopes the U-TR30 head fits, although it is not a complete list.

What is this part needed for?

• as a service part, in the form of replacing the whole component, when the mount in your head is in very poor condition or has, for example, cracked
• when you need a mount for fitting 42 mm Olympus tubes in order to use them in your own DIY project

This is description of this part:

Top part of the housing (cover) of the microscope trinocular head P/N 45 21 43 for Carl Zeiss Axioplan 2 microscopes.

Since this is a brittle casting, the housing can crumble, crack or break. The remedy for such a problem is then the replacement of the whole head or of this housing part only.

Inside the housing there is the eyepiece shutter together with the knob for sliding it.

This is the housing of the head, not the housing of the microscope. The 452143 head itself fits directly on the Carl Zeiss Axioplan 2, Axioplan 2 imaging and Axiophot 2 microscopes, and with the 452969 adapter it is also used on Axioskop 2 stands. This part therefore fits every 452143 head, regardless of which microscope that head is working on.

What is this part needed for?

• as a service part in the form of replacing the whole element, when the housing in your head is in very bad condition or has cracked, for example
• as a service part, if the eyepiece shutter or a part of it, e.g. the knob, has been damaged in your head

This is description of this part:

Carl Zeiss 45 21 49 tube lens, infinity corrected, in a metal mount with a thread.

Parameters of the Zeiss 45 21 49 lens:
Lens type: infinity corrected tube lens
Diameter including the mount: 38.5 mm
Thread: M36 x 0.75 (that is, 36 mm in diameter)
Anti-reflective coating: yes

This particular lens was removed from the Carl Zeiss P/N 45 21 43 head. The same tube lens model is fitted in various head models for Zeiss Axioplan 2 microscopes:
- Zeiss 452142
- Zeiss 452143
- Zeiss 452145
- Zeiss 452146

The Zeiss 452149 tube lens is necessary, among other things, to use infinity corrected Zeiss microscope objectives on microscopes of other manufacturers - including those with a finite 160 mm tube length. It is also very often used in super macro photography, to connect infinity corrected objectives to a photo camera.

This part can be the answer to the following questions:
- What to do when the Zeiss 452149 tube lens is damaged, scratched or of poor quality?
- Can Zeiss objectives be used on a microscope from another manufacturer?
- Can infinity corrected objectives be used on a 160 mm type microscope?
- How to take super macro photos using infinity corrected microscope objectives?

What is this part needed for?

• if this tube lens is missing in the head or in the tube of your microscope
• if your tube lens is damaged or of very poor quality, for example when fungus has attacked its anti-reflective coating
• if you want to use Carl Zeiss objectives on microscopes of other manufacturers, designed for a different tube length
