This is description of this part:

Stand for Carl Zeiss Jena Technival-2 and Citoval-2 stereomicroscopes.

This is a complete stand consisting of the following elements:
- base (foot) (Si 2490)
- metal plate for the base, black on one side and white on the other
- vertical steel post (stand)
- rack gear of the vertical movement mechanism
- focusing block with adjustment knobs (manufacturer's catalog name: Mikroskoptrieb 65 mm)
- holder to which the microscope body is mounted directly.
In the operating manual (https://www.mikroskop-online.de/Mikroskop%20BDA/30-725-1%20%20TECHNIVAL%202%20%20CITOVAL%202.pdf), these elements are numbered 1, 2, 3 and 35 on page 4.

Please note that the original rack gear used in Carl Zeiss Jena Citoval-2 microscopes is made of plastic and this component is very frequently damaged. If this particular element in your microscope has failed, Askania Mikroskop Technik Rathenow fortunately offers professionally manufactured brass rack gears for this microscope model (https://askania.de/products/zahnstange-messing-l-96mm).

Metal, cast or injection-moulded Carl Zeiss Jena parts carry their own identification numbers. This base (foot), into which the vertical stand post is screwed, bears the number 2490 (full designation: Si10 2490).

The Carl Zeiss Jena Technival and Citoval microscopes (older version without the number "2") are grey, while the Technival-2 and Citoval-2 models are white. This stand is white and is therefore intended for the newer Carl Zeiss Jena Citoval-2 and Technival-2 stereo microscopes.

What is this part needed for?

• if you own a microscope without a stand, which is very common on the secondary market
• if you own a stand of another type (for example a horizontal one) but need a classic vertical bench stand
• if you own a stand that is incomplete, damaged or of very poor quality
• please note that if you only need the rack gear itself, the description contains the address of a company that sells brass replacement parts

This is description of this part:

Halogen illuminator with holder for Carl Zeiss Jena Technival-2 and Citoval-2 stereo microscopes.

Basic parameters:
Illuminator type: reflected light (top illuminator)
Light source: 6V 25W halogen bulb, standard Narva HLWS5-A

This is a complete illuminator consisting of the following components:
- lamp housing with lenses for collimating the light beam
- light source with halogen bulb
- mounting holder for the Citoval-2 / Technival-2 microscope
In the user manual (https://www.mikroskop-online.de/Mikroskop%20BDA/30-725-1%20%20TECHNIVAL%202%20%20CITOVAL%202.pdf) these components are marked as items 7 and 8 on page 4.

Mechanically, this illuminator is mounted on an arm (illuminator holder), which can be clearly seen in the video attached to this description. This holder is attached to a special clamp located on the main objective.
The main objective of the Carl Zeiss Jena Citoval-2 / Technival-2 microscopes has two such clamps, allowing two holders and therefore two illuminators to be mounted. This allows the observed object to be illuminated from both sides. This is exactly why many users look for an additional illuminator.

This illuminator requires a transformer. It uses a 6V low-voltage halogen bulb and therefore cannot be connected directly to a mains power outlet.

The Carl Zeiss Jena Technival and Citoval microscopes (older version without the number "2") are grey, while the Technival-2 and Citoval-2 models are white. This illuminator is white and is therefore intended for the newer Carl Zeiss Jena Citoval-2 and Technival-2 stereo microscopes.

What is this part needed for?

• if you have a microscope with a missing illuminator
• if you have an incomplete illuminator, for example without the holder or without the light source
• if you have a damaged illuminator, for example with a light-beam collimating lens that has cracked due to the high temperature generated by the halogen bulb
• if you have a microscope with one illuminator but would like to install a second one to obtain illumination from two sides
• if you would like to use this illuminator with another microscope or for your own DIY project

Angle mirror for PZO Biolar microscopes.

Compatible with the following variants of the PZO Biolar microscope:
- PZO Biolar B
- PZO Biolar UPI (DIC)
- PZO Biolar P (Pol)
- PZO Biolar FL (Fluorescence)

The function of this component is to reflect light coming from the microscope base vertically upward so that, after passing through the specimen slide and the objective, it reaches the eyepieces and ultimately the user's eyes.

This cast component bears the marking "AK11", and this designation is commonly used on the secondary market to identify this particular angle mirror. However, it is not a part number, because the marking "AK11" can also be found on other PZO microscope components, which may lead to confusion. It is very likely that the source of this confusion is the attempt to compare PZO metal components with those used in Carl Zeiss Jena microscopes, where cast parts are marked with numbers in the format "Si10 CZ xxxxx". This may incorrectly lead people to assume that PZO used a similar numbering system.

Replacement of the angle mirror in PZO Biolar microscopes may be necessary in the following situations:
- if the mirror has become heavily scratched due to improper cleaning (minor scratches are usually not visible during normal use)
- if the silver reflective coating of the installed mirror becomes oxidized
- if the mirror becomes damaged, chipped, or cracked, for example after coming loose from its mounting

What is this part needed for?

• as a service part for replacement of the complete module

Biological microscope objective Carl Zeiss Jena Planachromat 25x with M19 thread for infinity-corrected systems.

Basic parameters:
- Element: biological microscope objective
- Manufacturer: Carl Zeiss Jena
- Designation: Planachromat 25x/0,50 oo/0,17
- Magnification: 25x
- Numerical aperture N.A.: 0,50
- Optical correction: infinity-corrected tube length
- Optical correction class: planachromat
- Cover glass: yes, 0.17 mm
- Thread: M19

Some facts about Carl Zeiss Jena objectives with M19 thread (CZJ M19) and their compatibility with various microscopes from this manufacturer:
- these objectives are most commonly used for technical applications rather than biological applications, therefore most objectives available on the secondary market are intended for use without a cover glass (designation oo/0)
- CZJ M19 objectives intended for biological applications (designation oo/0,17) are most commonly used on Carl Zeiss Jena NU / NU2 microscopes
- in Carl Zeiss Jena Nf and Lumipan microscopes, CZJ M19 objectives are used together with an EPI illuminator
- CZJ M19 objectives can be used in Carl Zeiss Jena Polmi-A microscopes, but they provide a different magnification than the nominal value
- Carl Zeiss Jena Amplival / Amplival Pol / Amplival Interphako / Peraval microscopes feature interchangeable nosepieces, and a dedicated nosepiece for M19-thread objectives was also produced for these microscopes
- Carl Zeiss Jena Metaval and Neophot microscopes use newer versions of CZJ M19 objectives (with a coarse-knurled edge and shiny housing), although many users still experiment with older M19 objectives on these microscopes
- Carl Zeiss Jena Epignost and BK 70x50 microscopes were produced in various versions with completely different configurations - and some of them operate with CZJ M19 objectives
- Carl Zeiss Jena Vertival / Epival / Nf / BK 70x50 microscopes often allow the use of CZJ M19 objectives in EPI dark-field mode
- on the Carl Zeiss Jena Epityp-2 inverted metallurgical microscope, many users employ biological objectives designed for use with a cover glass, placing the microscope slide "upside down", with the cover glass facing downward toward the objective.

Leitz Wetzlar microscope objective.

Manufacturer: Leitz Wetzlar
Magnification: 45x
Color correction: achromat
Numerical aperture: 0.65
Tube length: 170 mm
Focal length: 37 mm
Cover glass: yes, 0.17 mm
Immersion: no
Thread: RMS

This objective was removed from a Leitz Dialux microscope, but it is compatible with most Leitz Wetzlar microscopes manufactured approximately before 1980 (SM, SM-Lux, Dialux, Ortholux, Orthoplan, etc.).

Some useful information about Leitz Wetzlar objectives with TL=170 mm and FL=37 mm:
- most Leitz microscopes manufactured approximately before 1980 support both 160 mm and 170 mm tube length objectives
- many Leitz microscopes support both 37 mm and 45 mm parfocal length objectives
- by adding an RMS-8mm adapter, such an objective obtains a parfocal length of 45 mm. Leitz manufactured such adapters under the name "Plezzy" - however, many users make their own versions from metal or by using 3D printers

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

Special specimen cassette with microscope slide holder for Carl Zeiss Jena Jenamed series microscopes.

This cassette serves as a specimen holder with provision for microscope slides. It allows quick insertion and replacement of slides without the use of an XY mechanical stage.

Several different specimen holding systems are found in Carl Zeiss Jena microscopes. The slide cassette system is one of them and represents an alternative to traditional designs using a mechanical stage and slide-retaining clips.

Various names are commonly used for this specimen holder, including:
- slide cassette (German: Gleitkassette)
- specimen cassette (Ger.: Objektkassette)
- microscope specimen cassette
- specimen holder
- slide holder

This is not a complete stage-mounted system and therefore it is not a "slide cassette system". It is only the cassette itself (slide cassette), which is a replaceable wear item installed into the appropriate carrier assembly.

In the last gallery photograph, I indicate the exact component being offered with an arrow.

What is this part needed for?

• if you own a Carl Zeiss Jena Jenamed microscope that is missing this specimen cassette, which is very common on the secondary market
• as a replacement or consumable part if the existing slide cassette becomes damaged

This is description of this part:

Filter holder block for filter sliders used in Carl Zeiss Jena Jenamed microscopes.

This microscope component is located below the microscope head and above the objective nosepiece. It consists of slots (empty openings) into which filter sliders are inserted. This is the component that the Microscopy-UK portal (https://www.microscopy-uk.org.uk/mag/imgmar09/JenamedFinal.pdf) referred to as "in-tube filter holders".

This filter holder is compatible with the following Carl Zeiss Jena microscopes:
- Jenamed Variant
- Jenamed Cytology
- Jenamed Hematology
- Jenamed Histology
- Jenamed-2
- Jenamed Fluorescence

Metal, cast, and injection-moulded parts manufactured by Carl Zeiss Jena have their own identification numbers. This part bears the number: 2709/2 (full designation: Si10 CZ 2709/2).

Mechanically, this "block with empty slots" is attached to the casting numbered Si10 CZ 2708, which is the objective nosepiece block.

In the last photo of the gallery, I use an arrow to show exactly which component is being described.

This is description of this part:

Plastic microscope objective case made by PZO.

Case parameters:
Material: plastic
Length: suitable for DIN-45 objectives or shorter
Diameter: not intended for so-called "thick" objectives
Thread in the cap: no, the cap of this objective case does not contain a thread for attaching an RMS objective

This objective case can be used to store so-called "short" objectives (DIN 33 mm), longer objectives (DIN 37 mm), and long objectives (DIN 45 mm), provided they are not the so-called "thick" type.

For PZO objectives, it can accommodate all standard achromatic objectives as well as all phase contrast objectives. Some unusual PZO microscope objectives do not fit inside, for example the 100x PI objective (with a red ring).

Various names are used on the secondary market for a microscope objective case, including:
- objective case
- microscope objective case
- objective container
- microscope objective container
- objective storage case

This is description of this part:

Multi-tooth locking washer (alternative name: bendable tab washer) - a service component of the coarse focus and fine focus mechanism responsible for vertical movement in the microscope.

As far as I know, the same mechanism is used in the following Carl Zeiss Jena microscopes:
- Ergaval
- Amplival
- Fluoval
- Vertival
- Epival
- Docuval
- Metaval
- Peraval

This component is installed onto the shaft by sliding the internal tab into the keyway groove on the shaft. After tightening the round slotted nut, a locking mechanism is created that prevents the nut from loosening on its own due to vibration.

Split taper-lock bushing (alternative name: expansion and clamping ring) - a service component of the coarse focus and fine focus mechanism responsible for vertical movement in the microscope.

As far as I know, the same mechanism is used in the following Carl Zeiss Jena microscopes:
- Ergaval
- Amplival
- Fluoval
- Vertival
- Epival
- Docuval
- Metaval
- Peraval

This component acts as a resistance regulator and functions as a friction brake. Tightening the outer element compresses the tapered section of the bushing, causing the slotted bushing to contract at the slit. This increases friction on the shaft and makes the entire mechanism move with greater resistance.

Note - in some descriptions available on the Internet, this component is referred to as a "piece of wood".

This is description of this part:

Spring-loaded retaining screw for attaching a microscope head (for example a binocular head or trinocular head) to the stand of Carl Zeiss Standard series microscopes.

This particular screw was removed from a Zeiss Standard 14 microscope, but it will most likely fit most models of the Standard series, for example:
- Zeiss Standard GFL
- Zeiss Standard 16
- Zeiss Standard WL 89
- Zeiss Standard Universal
- Zeiss Standard Photomicroscope
- Zeiss Ultraphot

Note - over the years, Zeiss microscopes (or the same microscopes sold under the Zeiss-Winkel name or under the Opton brand), especially simpler models such as the Zeiss Standard Junior, used different types of head-retaining screws. These were not necessarily spring-loaded screws - in some cases ordinary threaded clamping screws were used instead.

Before deciding to replace the screw in a microscope, it is best to carefully compare its appearance and dimensions with the photographs in the gallery or ask a question on the forum https://www.mikroskopie-forum.de/

What is this part needed for?

• Sometimes this screw is missing in used microscopes.
• Very often, the tiny screw in this element is broken or missing.
• This element often has dried grease.
• This screw is often damaged because when it wouldn't turn due to dried grease, someone used pliers to turn it.

This is description of this part:

Blanking plug for the wide field lens lever (Zeiss P/N 47 30 65) for Carl Zeiss Standard series microscopes.

Zeiss Standard microscopes feature an optional wide field lens (Zeiss P/N 47 30 68). It can be installed in the tube between the objective nosepiece and the observation head. The lens is operated by a lever protruding from the side of the tube. In the manufacturer's documentation, this lever is referred to as "Switch to turn axis, e.g. with wide field changer 0.8x-1x". If this optional microscope component is not installed, the opening intended for the lever is closed with a plastic blanking plug additionally secured by a retaining screw. This listing includes exactly that end cap and screw.

This particular cover was removed from a Zeiss Standard 14 microscope, which is not normally equipped with the lever-operated lens. However, it will most likely fit the majority of other Standard series models, for example:
- Zeiss Standard GFL
- Zeiss Standard 16
- Zeiss Standard WL 89

The blanking plug itself carries the catalog number Zeiss 47 30 65 (alternative notation: Zeiss 473065) and is described as an "intermediate tube cover element".

Not only is this plastic cap frequently lost over the years, but the lever itself or the lens assembly may also become damaged and require removal. In such cases, this blanking plug should be installed to protect the microscope optics from dust.

In the last photographs in the gallery, I use arrows to show exactly which microscope component is being offered and where it is located within the microscope.

What is this part needed for?

• in some used microscopes, this blanking plug is missing
• over the years, the plastic from which this end cap is made may crack or become brittle
• if the wide field lens or its operating lever becomes damaged, the opening should be closed with this cover after removal of the assembly

This is description of this part:

Condenser holder module with a laterally movable iris diaphragm for obtaining DIC-like oblique illumination in the Carl Zeiss Jena Lu microscope (from the L-Stand family).

The Carl Zeiss Jena Lu microscope features a modular design (the same as the larger Carl Zeiss Jena Nf microscope). This microscope part (this module) consists of the following components:
- dovetail mounting with a clamping screw for attachment to the condenser lifting block
- condenser holder with a retaining screw for securing the condenser
- iris diaphragm (aperture diaphragm)
- iris diaphragm sliding carriage allowing lateral movement of the diaphragm
- eccentric mechanism allowing rotation of the carriage, making it possible to illuminate not only from the sides but also from the front or rear
- spring plate (lock) allowing the entire diaphragm assembly to be moved out of the optical path

The condenser holder has an internal mounting clamp for condensers with a diameter of 39.5 mm.

The movable iris diaphragm mounted below the microscope condenser allows oblique illumination and produces a three-dimensional image effect that increases the contrast of transparent specimens (for example individual unstained cells). This provides an effect similar to Differential Interference Contrast (DIC).

Various names are used on the secondary market for this microscope part, including:
- decenterable iris diaphragm
- decentering aperture diaphragm
- off-axis iris diaphragm
- eccentric iris diaphragm
- sliding iris diaphragm
- sliding iris
- oblique illumination condenser
- condenser with sliding iris
- oblique illumination module
- oblique illumination diaphragm
- offset iris
- Poor Man's DIC device

Note - this condenser module DOES NOT FIT Carl Zeiss Jena Nf, Ng, Lumipan, Polmi-A or Nu microscopes, even though the mounting arrangement appears very similar at first glance.

What is this part needed for?

• if you own a Carl Zeiss Jena Lu microscope that is missing this complete module
• if this microscope part is damaged or in very poor condition
• if you would like to install this diaphragm on another microscope
• if you need a movable iris diaphragm for your own DIY project

This is description of this part:

Aperture iris diaphragm for the Carl Zeiss Jena panchromatic microscope condenser used in Amplival-class microscopes.

Basic data:
Manufacturer: Carl Zeiss Jena
Version: grey version, removed from a Carl Zeiss Jena Amplival microscope
Mounting method: aperture diaphragm in the form of a detachable module
Centerable: yes

This iris diaphragm module is mechanically mounted to the bottom of the panchromatic condenser.

In Carl Zeiss Jena panchromatic condensers, the diaphragm is designed as a detachable module because it can be removed and replaced, for example, with a phase contrast module or a polarization module. Precisely because this microscope part can be detached, it is often missing from condensers available on the secondary market - over the years it simply gets lost.

Interestingly, this microscope part is very often modified. When users do not have a phase contrast module or a polarization module, they frequently insert polarizing film or custom-made phase rings into the aperture diaphragm module and obtain the functionality they need through DIY modifications.

This module can also solve a common problem found in Carl Zeiss Jena Amplival microscopes, namely damaged diaphragm blades in the condenser.

What is this part needed for?

• if you own a panchromatic condenser without an aperture diaphragm
• if you already own a panchromatic condenser with an aperture diaphragm, but the diaphragm is damaged or of very poor quality - which is very common
• if you need this microscope part for your own DIY projects

Knurled zoom ring with magnification scale for the Carl Zeiss Jena Citoval-2 stereomicroscope.

The function of the ring shown here is to change the magnification. The engraved scale on the ring allows the currently selected magnification to be determined.

In the Carl Zeiss Jena Citoval-2 stereomicroscope, continuous magnification adjustment (known as zoom) is implemented inside the microscope body (Greenough system), while the objective lens has a fixed focal length.

The set also includes a threaded retaining ring that allows this assembly to be mounted to the microscope body.

Additionally, in the last photo an arrow indicates which element is being referred to and where it is located in the microscope, in order to clearly identify this part.

What is this part needed for?

• if you have an incomplete microscope in which this component is missing, damaged or of poor quality

This is description of this part:

Dovetail rail used to mount the body of a Carl Zeiss Jena Citoval-2 / Technival-2 stereo microscope to a table stand.

The function of this microscope part is to attach the microscope to the stand. In the Carl Zeiss Jena Citoval-2 microscope user manual (https://www.mikroskop-online.de/Mikroskop%20BDA/30-725-1%20%20TECHNIVAL%202%20%20CITOVAL%202.pdf, page 4), the stand component to which this rail is fitted is identified as part number 35.

This rail is often chipped or broken because it is made of a relatively brittle material, while the screw used to clamp it to the stand is made of steel (this can be clearly seen in the following photo: https://www.microscopeparts.eu/photo/carl-zeiss-jena-citoval-2-technival-2-stereomikroskop-tischstativ-mit-fokussiertrieb-99477-7). An impact or even excessive tightening of this screw may cause this mounting rail to chip or break.

This microscope part can help solve the following problems encountered when using a Carl Zeiss Jena Citoval-2 or Technival-2 microscope:
- if you own a microscope that was previously used without its stand or on a custom boom arm and no longer has this mounting rail
- if this rail has been chipped or broken due to impact damage or material fatigue and the microscope can no longer be securely mounted to its table stand

Interestingly, this mounting rail is also an excellent component for adapting a microscope from another manufacturer to a table stand originally designed for Carl Zeiss Jena Citoval-2 / Technival-2 microscopes. It is sufficient to attach this mount to the microscope body (mounting screws are included).

In addition, the last photographs in the gallery include an arrow indicating exactly which part is being offered and where it is located within the microscope, allowing this component to be identified unambiguously.

What is this part needed for?

• as a service part when replacement becomes necessary. Examples of situations in which this component may be needed are provided in the description.

Leica SFL100 530 nm - LED fluorescence light source for Leica DMi8 / DM1000-DM3000 microscopes

Basic parameters:
Manufacturer: Leica
Model: Leica SFL100 530 nm
Manufacturer part number: 11504195
Light source type: LED
Wavelength: 530 nm
Light colour: green (TRITC)
Microscope mounting method: dovetail mount
Mounting diameter: 48 mm
Compatible microscopes: Leica DMi8 / DM1000 / DM2000 / DM2500 / DM3000
Compatible filter cube: 530 nm LED (for example P/N 11504156)
ON/OFF switch: integrated into the illuminator together with a potentiometer for light intensity adjustment

This illuminator provides intense green fluorescence illumination for:
- Leica DMi8 inverted microscope
- Leica DM1000-DM3000 routine microscopes

Similar illuminators with different light colours (wavelengths) include:
- P/N 11504196 Leica SFL100, 365 nm
- P/N 11504138 Leica SFL100, 470 nm

Important:
- the included power supply is not an original Leica power supply - it is a compatible unit manufactured by another company
- to work effectively with this wavelength, the microscope must be equipped with a suitable optical filter set (a fluorescence filter cube)
- due to legal safety regulations, this LED illuminator is not available within the U.S.A.
- when working with fluorescence illumination, care should always be taken to avoid eye damage

Light at 530 nm is commonly used in two optical configurations.

1. As excitation light (Excitation). It excites fluorescent dyes with yellow, orange and red emission spectra:
- Cy3 / Alexa Fluor 546 / Alexa Fluor 555 - widely used markers in immunofluorescence
- TRITC / Rhodamine - classic rhodamine dyes used for antibody and cytoskeleton (actin) labelling
- dTomato / mStrawberry - red fluorescent proteins used in in vivo studies

2. As an emission detection band (Emission). In the classic blue-light excitation configuration (for example with a 488 nm laser), 530 nm corresponds to the emission maximum (green fluorescence) of:
- GFP (Green Fluorescent Protein) - a standard marker in genetic engineering and cell biology
- FITC / Alexa Fluor 488 - the most commonly used dyes for labelling cellular structures
- Fluo-4 / Calcein - indicators used to measure calcium ion concentration and cell viability

This illuminator does not use any unusual microscope mounting method - it employs a standard 48 mm dovetail mount. As a result, it may be possible to adapt it to other Leitz or Leica microscopes and even to microscopes manufactured by other companies.

What is this part needed for?

• if you own a compatible fluorescence microscope but do not have a light source
• if you need a 530 nm green fluorescence illuminator for your microscope
• if you would like to install this illuminator on a microscope model other than those listed in the description or on a microscope from another manufacturer with a similar illuminator mounting diameter
• if you would like to use this LED light source in your own DIY projects

This microscope component allows simultaneous visual observation and image capture (photography or video recording) on the LOMO MBC-10 (Lytkarino) stereo microscope.

The designation MBC-10 is the Cyrillic spelling. The equivalent name written in the Latin alphabet is MBS-10.

The MBC-10 microscope was also sold under the following names:
- OGME-P3
- SF-100 (name used in the USA)
- Silver Connection MBC-10 (mainly on the German market)

These are exactly the same microscopes, therefore this trinocular attachment is also compatible with those models.

Manufacturer: LZOS Lytkarino
Manufacturer information: LOMO is commonly but incorrectly listed as the manufacturer
Model: MFU
Year of manufacture: 1995
Component type: photographic adapter / trinocular attachment
Light split: 50% of the light from one optical path is directed to the photographic output
Simultaneous observation: yes, the adapter operates in simul-focal mode and does not interrupt simultaneous viewing
Camera connection: M42 thread - with an appropriate adapter virtually any camera or imaging device can be connected

Mechanically, this photographic attachment is installed between the magnification changer and the binocular head.

Various names are commonly used for this camera adapter on the secondary market and in microscope literature, including:
- SF-FA (the name used in the USA)
- trinocular head
- trinocular attachment
- trinocular tube
- trino
- photo tube
- phototube
- photo adapter
- photographic adapter
- camera adapter
- camera attachment
- photo port
- camera port
- photo output
- camera output
- photomicrography adapter
- microscope camera adapter
- microscope photo adapter
- photo head
- camera head
- simul-focal adapter
- M42 photo adapter
- M42 camera adapter
- MBS-10 camera port
- stereo microscope photo tube

It is worth noting that this photo tube is not compatible with MBC-1, MBC-2 or MBC-9 stereo microscopes and does not fit any biological microscope - including biological microscopes manufactured by LOMO.

What is this part needed for?

• the MFU adapter is required if you want to perform photomicrography or record videos with an MBC-10 stereo microscope
• the MFU adapter is required if you want the microscope image to be displayed simultaneously on a computer monitor or screen (a feature widely used by jewellers and electronics technicians)

PZO Poland microscope objective with 40x magnification, 170 mm tube length and 33 mm parfocal length (the so-called short version).

Basic parameters of this PZO microscope objective:
Manufacturer: PZO Poland
Model: 40/0.65 170/0.17
Magnification: 40x
Correction: Achromat
Numerical aperture: 0.65
Tube length: 170 mm (very rare in PZO)
Focal length: 33 mm
Cover glass: yes, 0.17 mm thickness
Immersion: no (dry objective)
Thread: RMS

Please note that this objective was designed for microscopes with a 170 mm tube length. This refers to older PZO microscope models:
- PZO MinO
- PZO M100
- PZO ML1 / ML2 and ML3
- PZO MB1 and MB2
- however, this is definitely not a complete list

It can be used with any microscope capable of accepting RMS objectives with TL=170 mm and FL=33 mm. After installing a 12 mm adapter, this objective will of course have FL=45 mm.

Many microscopes from the 1950s and 1960s support both TL=170 mm and TL=160 mm objectives. Interestingly, in many microscopes designed for a 160 mm tube length it is possible to use objectives designed for a 170 mm tube length if the microscope eyepieces are pulled out by 10 mm in the head tube (a solution used in Leitz Wetzlar microscopes).

What is this part needed for?

• If you have an older PZO microscope without objectives and would like to complete it using original parts
• If you have a compatible microscope that lacks an objective of this magnification and would like to complete the set
• If you already have such an objective but it is damaged or of very poor quality
• If you are cautious and would like to keep such an objective as a spare

This is description of this part:

Pair (2 pieces) of SWF 5X eyepieces for Euromex E and Z series stereo microscopes

Basic parameters:
Manufacturer: Euromex Arnhem Holland
Model: S SWF 5x
Designation: SWF = Super Wide Field
Magnification: 5x
Field of view: 26
Compatibility: Euromex E and Z series stereo microscopes

This particular pair was removed from a Euromex Arnhem ES microscope equipped with an EE.1524 head (with 2x / 4x magnifications). Of course, they also fit the EE.1523 head with 1x / 3x magnifications.

Eyepieces with such a low magnification (5x) are used by users who need a large field of view and work with relatively large objects (electronics technicians, jewelers, engravers). In a microscope equipped with a 2x objective, installing 5x eyepieces results in a total magnification of 10x.

What is this part needed for?

• If you have a microscope without eyepieces and want to complete it using original parts
• If you have a microscope that is missing eyepieces of this magnification and want to complete it
• If you have such eyepieces but they are of very poor quality or damaged
• If you are cautious and would like to keep such eyepieces as spares

Condenser with iris diaphragm and flip-out top lens for the vintage Leitz Wetzlar Dialux microscope.

Note - this condenser is installed by sliding it into the guide rails of the condenser holder. It is not a condenser mounted in a circular clamp, therefore it does not have a "diameter" parameter describing it.

This condenser was removed from a Leitz Wetzlar Dialux microscope (the first black model), but to the best of my knowledge it also fits other microscopes from the same era: Leitz Ortholux and Leitz Orthoplan. Important - it does not fit Leitz SM microscopes.

The upper flip-out lens provides the best image quality when working with objectives of high numerical aperture (N.A.). When the upper lens is flipped out, optimal illumination is achieved when using objectives with magnifications below 10x.

What is this part needed for?

• if you have a vintage Leitz Dialux microscope that is missing its condenser and you would like to complete it using original period parts
• if you have a microscope with a condenser, but the condenser is of very poor quality or damaged (for example a damaged iris diaphragm or lens)
• if you have another Leitz Wetzlar microscope compatible with this condenser (for example a Leitz Ortholux)

Monocular head with Bertrand lens for 30 mm eyepieces for the Leitz Wetzlar SM-Pol polarizing microscope.

This is a specialized head designed for a polarizing microscope. The head contains a built-in Bertrand lens that can be moved out of the optical path. This allows both standard orthoscopic and conoscopic observations to be performed.

Basic parameters:
Manufacturer: Leitz Wetzlar
Compatible eyepiece diameter: 30 mm
Compatible eyepiece type: both standard eyepieces and polarizing eyepieces with a positioning key
Bertrand lens: yes, with an adjustment knob
Compatible with: Leitz Wetzlar SM-Pol microscope

Important: the non-polarizing versions of the Leitz Wetzlar SM microscope (and the SM-D) use a different head mounting system, therefore this head is not compatible with those models.

In the last photograph, an arrow indicates exactly which component is being offered and where it is located within the microscope, allowing this part to be identified unambiguously. In addition, the attached video shows, among other things, the mechanism used to move the Bertrand lens.

What is this part needed for?

• if you own a Leitz SM-Pol polarizing microscope with a missing head
• if you own such a head but it is of very poor quality or damaged
• if you would like to keep such a head as a spare part
• if you would like to install it in another microscope (which may require DIY modifications)

Heine microscope condenser made by Leitz Wetzlar.

A Heine condenser allows smooth, continuous switching between different observation techniques:
- bright field
- dark field
- oblique illumination
- phase contrast

It can work with phase objectives of different magnifications and from different manufacturers (it is sufficient to manually adjust the ring diameter).

Basic parameters:
Manufacturer: Leitz Wetzlar
Model: Heine condenser
Mounting diameter: 39.5 mm
Numerical aperture N.A.: variable, up to 1.4

This Heine condenser was designed for microscopes with a condenser holder in the form of a circular clamp (e.g. Leitz SM microscopes). It is not a condenser that slides into mounting rails (as found, for example, in the Leitz Orthoplan microscope).

This condenser fits microscopes from many manufacturers (e.g. PZO, Steindorff Berlin, Zeiss, Carl Zeiss Jena, Leitz, Kremp Wetzlar, Will Wetzlar and many others) equipped with a 39.5 mm condenser holder.

What is this part needed for?

This is description of this part:

20x microscope objective made by Lomo with the LZOS Lytkarino factory logo and a unique "golden" serial number.

Manufacturer: LZOS Lytkarino (commonly, although incorrectly, referred to as "Lomo")
Model: 20 0,40
Magnification: 20x
Correction: Achromat
Numerical aperture: 0.40
Tube length: 160 mm
Focal length: 33 mm
Cover glass: 0.17 mm
Immersion: no
Thread: RMS
Serial number: 01234

It can be used with any microscope from any manufacturer. Of course, the microscope must be compatible, i.e. support RMS objectives, TL=160 mm and FL=33 mm.

After installing a 12 mm adapter, this combination of adapter and objective will function as an objective with FL=45 mm.

This objective is attractive mainly to collectors because:
- there are very few microscope objectives with the LZOS logo on the secondary market
- the objective has a so-called "golden serial number": 01234

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
• If you're cautious and want to have a spare objective lens

Rotating polarizing microscope stage for transmitted light work for the Leitz Wetzlar SM-Pol polarizing microscope.

Manufacturer: Leitz Wetzlar
Type: stage for transmitted light work
Mounting method: this stage is attached to the microscope body using screws
Centering: in the Leitz Wetzlar SM-Pol microscope, this stage is centered using two screws

Many users of the Leitz Wetzlar SM microscope (or SM-D) ask the following question:
- Can I install the polarizing stage from the Leitz SM-Pol microscope into a Leitz SM microscope and thus convert it into a polarizing microscope?
- The answer is: No. The centering mechanism of this polarizing stage means that this stage is not compatible with the non-polarizing Leitz SM microscope. Moreover, the Leitz SM microscope differs from the polarizing SM-Pol model not only in the stage.

In the last photo, an arrow indicates which element is being offered and where it is located in the microscope, allowing this part to be identified unambiguously. Additionally, the attached video shows the movement mechanism of this stage.

What is this part needed for?

• as a service part if the stage in your microscope has been damaged
• if you would like to try installing this stage in another microscope
• if you need a precise rotating stage for your own DIY project, for example related to macro photography

This is description of this part:

Lamp house and EPI condenser for the Lomo MMU-3 / MMY-3 metallurgical microscope.

This part is a component of the illumination system of the Lomo MMU-3 microscope. The light source is inserted into this housing (the standard light source in this model is an 8V 20W bulb). The entire housing is covered with dense metal fins acting as a heat sink to dissipate heat. At the end of this housing there is a condenser lens collimating the light beam and a dovetail mount. This mount is used to attach the condenser to the next element of the illumination path, namely the holder with a slot for insertable sliders.

The model designation MMU-3 is written using the Latin alphabet. When written in Cyrillic, this designation looks like MMY-3, and people unfamiliar with the Cyrillic alphabet may therefore refer to this microscope model in that way.

Interestingly, the dovetail connection used here has a diameter of 41.5 mm, which is the standard mounting diameter for accessories (for example microscope heads and intermediate tubes) not only in Lomo microscopes, but also in Carl Zeiss Jena, Romanian IOR, Czechoslovak Meopta and many other microscopes. For this reason, this lamp housing is sometimes used as an EPI reflected light source in various Carl Zeiss Jena microscope modifications.

In the last photograph, on the scanned page from the instruction manual of the Lomo MMU-1 microscope, an arrow indicates which element is being offered and where it is located in the microscope, allowing this part to be identified unambiguously.

What is this part needed for?

Original wooden box No. 2 (protective and transport case) for storing accessories for the Lomo Polam polarizing microscope.

Lomo Polam polarizing microscopes in their standard configuration were supplied with three wooden boxes:
- the main microscope case
- a smaller accessory case (Case No. 1)
- a larger wooden carrying case for accessories (Case No. 2)
The box presented here is Case No. 2. This particular example originally comes from a Lomo Polam L-211 microscope, but it can also be used to store accessories from other Lomo Polam models.

Various names are used on the secondary market for this type of wooden microscope box, including:
- wooden accessory box
- microscope accessory case
- microscope accessory storage case
- microscope accessory carrying case
- protective case for microscope accessories
- wooden storage case for microscope parts
- transport case for microscope components
- wooden instrument case
- fitted wooden case for microscope accessories
- wooden carrying case for microscope attachments
- storage box for microscope eyepieces and objectives
- original microscope accessory case

A millimetre scale is visible in all photographs, but I intentionally do not provide the dimensions of this case in the description, even though this would normally be considered good practice. I simply believe that mainly (or perhaps only?) users of Lomo Polam polarizing microscopes will be interested in it, as they may wish to store original accessories in an original wooden case.

The last photograph shows the original Lomo label with the factory arrangement of the contents of this case. This will definitely help the user place the appropriate components in the correct compartments.

This is description of this part:

Matt frosted filter (ground glass diffuser) for the condenser of a Lomo Polam polarizing microscope.

This matt filter acts as a diffuser. It transforms the harsh light from the lamp into homogeneous illumination, makes the lamp filament invisible and ensures that the entire specimen is illuminated evenly.

The filter is mounted on a swing-out holder, which is a separate module installed below the condenser. This allows the entire frosted diffuser to be swung out of the optical path. In this position, for example, illumination according to the Koehler standard can be adjusted.

Users employ various names for the matt filter mounted below the condenser. These include:
- matt filter
- frosted filter
- ground glass diffuser
- diffuser
- diffuser filter
- frost filter
- opal diffuser
- diffusing screen
- condenser diffuser
- swing-out diffuser

In the last photograph, an arrow indicates which microscope element is being offered and where it is located in the microscope, allowing this part to be identified unambiguously.

The holder with the frosted diffuser fits every model of the Lomo Polam microscope series (the model designation written in Cyrillic is given in parentheses):
- Lomo Polam S-111 (the Cyrillic designation looks like C-111)
- Lomo Polam S-112 (C-112)
- Lomo Polam R-111 (P-111)
- Lomo Polam R-112 (P-112)
- Lomo Polam R-113 (P-113)
- Lomo Polam L-211
- Lomo Polam L-213
- Lomo Polam LMPR
- also Lomo Polam R-312 and Lomo Polam R-311 (the Cyrillic designation is P-312 and P-311), although in these models the matt filter below the condenser is usually not required because these microscopes are intended primarily for reflected light work

The final photograph, in which I indicate with an arrow the mounting position of the diffuser below the condenser, is a poster containing a comparison table of various Lomo Polam microscope models. It will help you easily identify which model of Lomo Polam polarizing microscope you own.

What is this part needed for?

• if you own a Lomo Polam series microscope without the matt filter below the condenser and would like to complete it with this missing microscope part

This is description of this part:

Double-sided mirror for a Lomo Polam polarizing microscope.

Lomo Polam microscopes (all models except the Lomo Polam LMPR, Polam L-211 and Polam L-213) do not have a built-in illuminator integrated into the microscope stand. Instead, they use external Lomo illuminators mounted on the microscope, for example the simple Lomo OI-32 illuminator or the Lomo OI-35 Koehler illuminator.

Users who require a more powerful light source for their work (for example 100 W) often use external illuminators mounted on separate stands - and this mirror is used to redirect that light into the optical system. Users also frequently experiment with different types of illumination (quartz, halogen, red or fluorescent light) - and this mirror is intended for such applications as well.

Mechanically, the mirror is integrated with a mounting base having a diameter of 43.5 mm, exactly matching the opening in the microscope base. When installed in this way, the mirror is stable and allows comfortable operation with high-power external light sources.

The last photograph in the gallery is a poster containing a comparison table of various Lomo Polam microscope models. It allows you to see exactly where and which illuminators are mounted in different Lomo Polam microscopes - and therefore also where this mirror is installed.

What is this part needed for?

• if you own a Lomo Polam series microscope and would like to use an external light source
• if you want to experiment with different types of external illumination such as quartz, halogen or even fluorescent light
• if you own a Lomo Polam microscope without this mirror and would like to complete the original set

This is description of this part:

Photo tube / camera adapter for the Lomo TRN-1 trinocular head used in Lomo Polam microscopes - but also compatible with many other microscopes manufactured by Lomo, Carl Zeiss Jena, PZO, Meopta, Olympus, IOR and others.

This tube makes it possible to connect a camera or photographic camera to a trinocular head or directly to the microscope body, even when no trinocular head is installed.

Originally, this adapter was designed for the Lomo TRN-1 trinocular head. This head was used in Lomo Polam polarizing microscopes from the early 1970s onwards.

Several remarks regarding the model designation of the trinocular head for which this component was originally intended:
- the name Lomo TRN-1 is the Latin alphabet designation. In Cyrillic script the model designation appears as TPH (for example model TPH1Y4.2), and this designation is used in the manual for the Lomo Polam L-211 microscope
- the vast majority of these trinocular heads are not marked with any model designation
- the Envirotools website http://www.envirotools.hu/ateso_fenyu_polarizacios_mikroszkop.htm refers to this trinocular head as HU-POL

In the last photograph, an arrow indicates exactly which component is being offered and where it is located in the Lomo Polam microscope, allowing this part to be identified unambiguously.

Basic technical parameters of this tube:
Mounting method to the trinocular head or microscope: 41 mm dovetail mount (this is also the Carl Zeiss Jena standard)
Camera mounting method: male M39 thread
Alternative camera mounting method: since the M39 thread can be removed, a plain smooth tube with a diameter of 35 mm remains
Additional optics: yes, the original optics are installed inside, although they can be removed, leaving only an "empty tube".

This is not "a tube dedicated to a specific microscope model". It is a tube originally mounted on the third port (photo port) of a trinocular head. Since a trinocular head can be installed on microscopes other than the model with which it was originally supplied, this tube can be regarded as a universal accessory.

These technical parameters make it possible to use this tube with virtually any microscope manufactured by:
- Lomo (for example Biolam, Polam, MBB-1A and others)
- Carl Zeiss Jena (for example Ergaval, Amplival, Jenamed and others)
- IOR, Meopta and other manufacturers using a 41 / 41.5 mm dovetail mount

In addition, a 41 mm dovetail tube can easily be mounted on microscopes equipped with a 42 mm or 43 mm opening, for example:
- Olympus (for example CH, CH-2, BH-2 models)
- PZO (for example Biolar, Studar, MB-30 and others)

The entire list of microscope manufacturers and models given above may also be treated as a list of microscopes compatible with the Lomo TRN-1 trinocular head. Indeed, many examples can be found on the Internet showing this head being used with microscopes made by manufacturers other than Lomo.

Because this tube is equipped with an M39 thread by default, almost any camera or photographic camera can be attached by means of a suitable adapter, for example:
- devices with M42 threads
- devices with C-mount threads
- Nikon, Sony, Olympus and other camera standards

This is therefore a universal photo tube featuring a 41 mm dovetail on one side and either an M39 thread or a 35 mm tube on the other side.

In the image gallery, every photograph includes a millimetre scale, and in addition, the dimensions of the dovetail, tube and thread have been measured with calipers so that compatibility can be determined precisely.

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:

EPI slider with a darkfield stop, frosted diffuser filter and iris diaphragm for the Lomo MMU-3 / MMY-3 metallurgical microscope.

The function of this mechanism is to switch the reflected-light operating mode between darkfield and brightfield observation.

This slider is inserted into a slot located in the Lomo MMU-3 microscope between the microscope body and the lamp housing.

This slider has two positions:
1. Darkfield stop (darkfield disc). When the slider is set to this position, the microscope can be used for reflected-light darkfield observations.
2. Frosted diffuser filter with an iris diaphragm. When the slider is set to this position, the microscope can be used for reflected-light brightfield observations.

In the last photograph, an arrow indicates which component is being offered and where it is located in the microscope, allowing this microscope part to be identified unambiguously.

What is this part needed for?

• if you own a Lomo MMU-3 microscope without the EPI illumination slider
• if you already have such a slider but it is of poor quality or damaged, for example if the iris diaphragm control knob is broken, the darkfield disc is damaged, the frosted diffuser filter is cracked, or the iris diaphragm is defective
• if you would like to use this slider for your own DIY project or in another microscope

Condenser height position limiter for Lomo Polam polarizing microscopes.

In Lomo Polam polarizing microscopes, a swing-out frosted diffuser module can be mounted below the condenser. In most microscopes this module is installed, but it is a separate accessory and does not have to be present. Directly below it is the location where the component offered here is mounted.

This component performs at least two functions:
- it limits the vertical movement of the condenser and specifically prevents it from being lowered too far
- it acts as a blanking plate if there are no additional accessories installed below the condenser diffuser

However, if this component serves as a blanking plate, what other accessories can be mounted there? The most commonly encountered optional accessory for Lomo Polam microscopes is the Lomo MIP-2 monochromator (this is the model designation written in the Latin alphabet). Since this is optional equipment, this blanking plate performs its function exactly at this location.

This blanking plate is also attractive to users who need an original mounting point below the condenser (appropriate dovetail mount and clamping screw - this blanking plate provides all of these features) in order to attach their own DIY accessory intended to be placed in the optical path.

In the last photograph, an arrow indicates which component is being offered and where it is located in the microscope, allowing this microscope part to be identified unambiguously.

What is this part needed for?

• if you own a Lomo Polam series microscope without this component and would like to complete the original equipment set
• if you already have such a blanking plate but need another one for modification as part of your own DIY project

Slide with a rotatable polarization analyzer for Reichert Austria Zetopan and MeF-2 microscopes.

360 degree rotatable analyzer in the form of a slide (slider).
Manufacturer: Reichert Austria
Compatibility: Reichert MeF-2 metallurgical microscope and the Reichert Zetopan microscope series (all models)
Rotation: 360 degrees with 0.1 degree accuracy using a vernier scale

If you would like to use this slide with a different microscope - carefully check the dimensions shown in the photographs.

Note - there is some confusion in commonly used terminology and foreign or even incorrect names are often used. The most common mistake is that the analyzer is referred to as a polarizer - and unfortunately this mistake is so widespread that it has to be taken into account. Examples of names used by microscope users include:
- polarizer
- polariser
- polarization filter
- polarising filter
- POL filter
- circular polariser
- CPL filter
- analyzer
- analyser
- analyzer slide
- analyzer filter
- POL analyzer
- polarization analyser
- polarization analyzer

This slide has two positions:
- for brightfield operation (zero glass with anti-reflection coating)
- for polarized light operation (rotatable polarization filter).

In the photo gallery you will find the exact dimensions of this slide, and the last photograph contains an excerpt from the Zetopan microscope manual showing this component. Additionally, the attached video demonstrates the filter rotation mechanism operated by the vernier scale.

What is this part needed for?

• if you have a compatible microscope but this polarization filter slide is missing
• if you already have such an analyzer but it is damaged or in very poor condition
• if you would like to use this slide with a different microscope
• if you need a high-quality rotatable polarizer for your own DIY project

Service part for repairing the Lux-US halogen illuminator housing (12V 100W) for the Reichert Zetopan microscope.

Module forming part of the Lux-US illuminator housing consisting of:
- dovetail mount with clamping screw used to attach the Lux-US illuminator to the Reichert Zetopan microscope
- intermediate tube with two slots for filter slides
- iris diaphragm (more precisely: field diaphragm)
- lens for collimating the light beam with focusing adjustment for the lamp filament

Information from the manufacturer's English-language catalogue "Zetopan Research Microscope. Price List, Effective December 1, 1976":
- This component belongs to the microscope illuminator. The catalogue number of the illuminator is: "Lux US" 9 14 41 04 and "Binolux 3 dual lamp housing" 9 60 05 21

In the photo gallery you will find precise dimensions of this microscope part, and the last photograph shows the complete Lux-US illuminator for the Reichert Zetopan microscope so that compatibility can be confirmed with certainty. In addition, the attached video demonstrates the mechanics of the moving components.

Older versions of the Reichert Zetopan microscope were equipped with a 6V 30W illuminator, while newer versions used the Lux-US illuminator with a 12V 100W halogen bulb. Currently (as of 2026), most hobby users of this microscope believe that this illuminator should be converted to an LED light source, whereas professional users still prefer a halogen bulb as a light source because it provides a full colour spectrum.
However, in both cases this illuminator housing is essential and must be repaired if damaged. Since it protrudes beyond the outline of the microscope (it is attached to the rear of the microscope base), it is exposed to mechanical damage.

What is this part needed for?

• as a service part (repair component) if you own a microscope equipped with this illuminator and this part has been damaged
• as a component for building a custom DIY illuminator: it allows any light source to be attached to the base of a Reichert Zetopan microscope

This is description of this part:

Service part for repairing the Lux-US halogen illuminator housing (12V 100W) for the Reichert Zetopan microscope and other microscope models using an illuminator in this housing design.

This is a finned heat sink mounted on the top of the halogen illuminator housing.

Important: The Lux-US halogen illuminator was used exclusively in Reichert Zetopan microscopes.

Reichert Diapan and Reichert MeF-2 microscopes do not use the Lux-US illuminator. However, the illuminators used in these microscopes have an identical mechanical housing and use the same radiator.

Therefore, the radiator offered here is also compatible with these microscopes - it is a repair part for the illuminator housing rather than for a specific microscope model.

Information from the manufacturer's English-language catalogue "Zetopan Research Microscope. Price List, Effective December 1, 1976":

However, in both cases this illuminator housing is essential and must be repaired if damaged. Since it protrudes beyond the outline of the microscope (it is attached to the rear of the microscope base), it is exposed to mechanical damage. The relatively soft cooling fins are susceptible to damage, and in the case of a 100W halogen illuminator efficient passive cooling is very important.

This is description of this part:

Repair component for the Lux-US halogen illuminator (12V 100W) used in the Reichert Zetopan microscope and other microscope models using an illuminator with the same housing.

This is a spherical rear reflector mirror mounted inside the halogen illuminator behind the lamp. The function of this element is to collect and reflect the light that "shines backwards and escapes" and direct it towards the collimating lens.

Important: the Lux-US halogen illuminator was used exclusively in Reichert Zetopan microscopes.

Reichert Diapan and Reichert MeF-2 microscopes do not use the Lux-US illuminator, however the illuminators used in these microscopes have an identical mechanical housing and use the same rear reflector mirror.

Therefore, the mirror presented here is also compatible with these microscopes - it is a repair part for the illuminator rather than for a specific microscope.

Older Reichert Zetopan microscope models were equipped with a 6V 30W illuminator, while newer models used the Lux-US illuminator with a 12V 100W halogen lamp. Currently (as of 2026), most amateur microscope users believe that this illuminator should be converted to an LED light source, while professional users still prefer a halogen bulb as a light source because of its full colour spectrum.
However, in both cases this lampenhaus is essential and must be repaired if damaged. Since it protrudes beyond the outline of the microscope (it is attached to the rear of the microscope base), it is exposed to mechanical damage. The mirror located directly next to the light source is susceptible to damage, among other reasons, due to exposure to high temperatures. In addition, over the decades the mirror surface may oxidise, causing the mirror to lose its optical properties and the entire illuminator to lose brightness.

Information from the manufacturer's English-language catalogue "Zetopan Research Microscope. Price List, Effective December 1, 1976":

This is description of this part:

Repair component for the Lux-US halogen illuminator (12V 100W) used in the Reichert Zetopan microscope and other microscope models using an illuminator with the same housing.

This is a lamp socket (plug-in assembly with bulb) that slides into the illuminator housing.

Important: the Lux-US halogen illuminator was used exclusively in Reichert Zetopan microscopes.

Reichert Diapan and Reichert MeF-2 microscopes do not use the Lux-US illuminator, however the illuminators used in these microscopes have an identical mechanical housing and use the same lamp socket.

Therefore, the lamp socket presented here is also compatible with these microscopes - it is a repair part for the illuminator rather than for a specific microscope.

Currently (as of 2026), most amateur microscope users believe that this illuminator should be converted to an LED light source, while professional users still prefer a halogen bulb as a light source because of its full colour spectrum.
However, in both cases this lampenhaus is essential and must be repaired if damaged. Since it protrudes beyond the outline of the microscope (it is attached to the rear of the microscope base), it is exposed to mechanical damage.

The lamp socket is particularly sought after by users who want to convert the illuminator to a different light source, for example LED. For this purpose, the plug-in assembly usually needs to be modified irreversibly - and it is best to do this using a "spare" lamp socket rather than "destroying" the original one.

Note - this lamp socket does not include the plastic end cap. It is not essential for operation - however, I would like to point this out.

In the photo gallery you will find the exact dimensions of this element, and the last photo shows the complete Lux-US illuminator for the Reichert Zetopan microscope, allowing compatibility to be confirmed with certainty.

What is this part needed for?

• as a service component (repair part) if you own a microscope with this type of illuminator and this part of the illuminator has been damaged
• if you want to convert your illuminator to an LED light source, but do not want to sacrifice your existing lamp socket for the DIY conversion

This is description of this part:

Microscope objective manufactured by Leitz Wetzlar with 100x magnification, designed for brightfield and phase contrast work.

Manufacturer: Leitz Wetzlar
Model: 160/0,17 EF 100/1.25 OEL PHACO 3
Magnification: 100x
Correction: semi-plan achromat
Numerical aperture: 1.25
Tube length: 160 mm
Focal length: 45 mm
Cover glass: yes, 0.17 mm
Immersion: yes, oil
Thread: RMS
Specimen protection: yes - spring-loaded
Info: PHACO 3 = phase contrast

Some important information about this objective:
- the designation "EF" means "Extended Field" - this is a semi-plan achromatic objective with an 18 mm field of view, which should be taken into account when selecting suitable eyepieces
- the semi-plan achromatic correction is "almost flat" - it is no longer an achromat, but not yet a plan achromat
- this objective can be used in brightfield, but phase contrast operation requires a compatible phase contrast condenser or a slide (slider) with a phase ring diaphragm
- the designation PHACO 3 means that for phase contrast operation a phase contrast condenser set to ring "3" should be used (the equivalent setting used by Zeiss is called "Ph3")
- this objective can be used with microscopes designed for objectives with a 170 mm tube length, but in such a case the optical path must be extended by 10 mm - most commonly by pulling the eyepieces out of the tubes by 10 mm

This objective can be used with any microscope from any manufacturer together with a compatible phase contrast condenser. Naturally, the microscope must be compatible, i.e. it must support RMS objectives, TL=160 mm and FL=45 mm - or have adapters that make such adaptation possible (for example thread adapters).

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
• If you're cautious and want to have a spare objective lens

This is description of this part:

Plan compensating microscope eyepieces manufactured by Carl Zeiss Jena with a high magnification of 20x.

Manufacturer: Carl Zeiss Jena
Model: PK 20x (8)
Magnification: 20x
Field of view: 8
Mounting diameter: 23.2 mm
Designation: PK = plan compensating - recommended for use with plan achromatic objectives, but they also work perfectly with achromatic and apochromatic objectives

Due to their very high quality, these eyepieces are often used together with microscopes from other manufacturers, especially when Carl Zeiss Jena Planachromat objectives are installed.

Important: these eyepieces can be used both with finite tube microscopes (e.g. 160 mm) and infinity-corrected microscopes. This means that they can be used, for example, both on a Carl Zeiss Jena Amplival microscope and on a Carl Zeiss Jena NU-2 microscope.

Note - in my opinion, eyepieces with such a high magnification are recommended rather for "inspection" than for continuous work. I deliberately write "I recommend" because this is my personal opinion based on practical use and not on the manufacturer's documentation.
An eyepiece magnification of 20x should rather be treated as a zoom without revealing additional details (the resolution is not increased). This is important, for example, in heads with built-in magnification (e.g. Carl Zeiss Jena heads with built-in magnification of 1.5x or 1.6x) - when working with a 100x oil immersion objective, we theoretically obtain 100*1.5*20 = 3000x, while physics does not allow the human eye to magnify visible light beyond approximately 1250x - therefore this is a so-called "empty magnification".

What is this part needed for?

• if you don't have these eyepieces in your set
• if you have 20x 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:

A set of five special diaphragms in a holder for the polarizing condenser of a Lomo Polam microscope.

A set of five such special diaphragms was supplied together with the Lomo Polam polarizing microscope. The set included phase contrast diaphragms and dark field diaphragms. Here I present and offer a complete set.

Important note:
Such diaphragms in a special holder were supplied as a set of five diaphragms as an accessory for the Lomo Polam polarizing microscope. These diaphragms are mounted onto the polarizing microscope condenser to obtain a combination of these techniques and a phase image in polarized light. Please note that the same condensers can also be used in polarizing microscopes of the Lomo MIN series (for example Lomo MIN-6 or Lomo MIN-8 models) and in microscopes designed for infrared light work from the Lomo MIK series (for example Lomo MIK-4). This means that there is nothing preventing the use of these phase rings in those microscopes as well.

The latest version of the Lomo Polam microscope, namely the Lomo Polam LMPR model, no longer requires this accessory. The Lomo Polam LMPR already features a dedicated rotating polarizing phase condenser (somewhat similar to the Lomo KF-4 condenser).

The last photo in the gallery shows a page from the Lomo Polam microscope manual where this microscope part is presented. In the manual it is shown in figure number 6, item number 65.

If you have such a set but it is incomplete - browse this database - you will also find individual diaphragms offered separately - specifically to solve such situations.

What is this part needed for?

• if you have a compatible Lomo condenser and want to use this special phase contrast diaphragm
• if you want to combine several observation techniques, for example polarization and phase contrast at the same time

This is description of this part:

4-position interchangeable objective nosepiece made by Reichert Austria for Zetopan series microscopes.

The oldest black version of the Reichert Zetopan microscope was equipped with objective nosepieces featuring a glossy surface (it may be described as a mirror-like surface). Newer Zetopan microscopes have matte nosepieces (they may be described as silver or gray). Here I present and offer a newer matte (gray) nosepiece.

Information from the manufacturer's English-language catalogue "Zetopan Research Microscope. Price List, Effective December 1, 1976":
- Catalogue number of this part: 9 03 12 05
- English name of this part: Quadruple nosepiece, on slider

When new Reichert Austria Zetopan microscopes were purchased with additional equipment (phase contrast or fluorescence), the manufacturer often supplied the microscope from the factory with two or three nosepieces (for example a dedicated nosepiece fitted with phase contrast objectives) - even 6-position versions!

The objective positions originally installed in each thread are engraved on the nosepiece presented here: 4 / 10 / 40 / 63. This is only a recommendation and any objectives may be screwed into these positions.

Important: the visually very similar black Reichert Neozet microscope uses a DIFFERENT objective nosepiece mounting system. The nosepiece from the Reichert Zetopan microscope is not compatible with the Reichert Neozet microscope.

Why is this the microscope part that every user should own in several examples?

Reichert Zetopan microscopes - both the older black models, the silver models and the latest cream-colored models - feature an interchangeable objective nosepiece. This is an excellent solution that allows complete sets of objectives to be owned, used and exchanged very quickly.

For example, you may have separate nosepieces already fitted with objectives:
- a set of low magnification objectives for observing macro objects with side illumination and without a cover glass (for example 2.5x / 3.2x / 5x / 8x)
- a complete set of objectives for phase contrast
- even different sets of objectives for different phase contrast techniques (positive, anoptral, amplitude, Zernike)
- a set of objectives for water immersion work, for example good and inexpensive Lomo objectives
- a set of objectives that all operate with oil immersion, for example Leitz Wetzlar 10x Oil / 25x Oil / 40x Oil
- a complete set of apochromatic objectives for obtaining better color reproduction
- a set of "P / Pol" objectives for polarization
- a complete set of objectives with only high magnifications, for example for analysis of cell wall ornamentation (50x / 63x / 80x / 100x)
- a set for dark field microscopy (objectives with an iris diaphragm inside)

Thanks to this, having only one microscope, we can use it for many different purposes without having to screw in and unscrew all objectives manually one by one every time.

Interestingly, regardless of the country (!) users often use English terms when referring to an objective nosepiece. The most common are:
- revolver
- objective nosepiece
- objective turret
- objective carousell

What is this part needed for?

• if you have a microscope without a turret
• if you need an additional turret
• if your turret is damaged

LOMO СЛ1/4λ (Latin alphabet transcription: SL1/4lambda) Quarter-wave plate - standard variant with diagonal axis (45 degrees) for Lomo Polam polarizing microscopes

Lomo microscope compensating slider:
Factory marking: СЛ1/4λ
Crystal material: Mica
Optical retardation: 1/4 lambda (approx. 140 nm)
Orientation of optical axes: diagonal, 45 degrees relative to the slider body edge

Dimensions:
Total length: 80 mm
Insertion length: 60 mm
Width: 19 mm
Height: 7,5 mm

Quarter-wave compensating slider (quarter-wave plate) introducing a phase shift of 1/4 wavelength. Used for standard compensation, determination of the optical sign of minerals, and analysis of elliptically polarized light.

The axes of the fast ray (Np) and slow ray (Ng) are oriented at 45 degrees relative to the longitudinal axis of the slider. This is the standard configuration used in the vast majority of classic polarizing microscopes, where the accessory slot is parallel to the microscope arm and the vibration axes of the crystal must align precisely with the diagonal of the polarizer and analyzer directions.

A second variant of this slider is also available - of the Sénarmont type, designated by the abbreviation CP-QS (Compensating Plate, Quarter-wave Sénarmont). In the Sénarmont configuration, the crystal axis (Ng) runs parallel to the vibration direction of the polarizer, and the 45-degree effect is enforced by the microscope accessory slot - not by the orientation of the crystal within the body. The Sénarmont variant is intended for specialized LOMO microscope heads with a 45-degree-rotated accessory slot and for precise quantitative measurements of optical retardation in combination with a rotating analyzer and an interference filter (typically 546 nm or 551 nm). Before purchasing, please check the design of your microscope. Using the incorrect variant will cause the crystal axes to misalign with the vibration direction of the polarized light, preventing proper background extinction as well as precise measurements and conoscopic observations.

What is this part needed for?

• If you have a polarizing microscope and you are missing this compensator on the slider
• If you have this slide, but it's damaged (e.g., delamination)
• If you want to use this quarter-wave plate for other DIY purposes

This is description of this part:

Spring-loaded specimen holder for the mechanical XY microscope stage used on various Leitz Wetzlar microscope models.

This particular specimen holder was removed from a Leitz Dialux microscope. In the last photo in the gallery you can see the microscope stage from which it was removed. However, the manufacturer fitted the same type of mechanical XY microscope stage to many other Leitz microscope models, so this specimen holder is also compatible with models other than the Leitz Dialux.

When determining compatibility and whether this specimen holder can be mounted on a particular mechanical XY microscope stage, the following dimensions are critical:
- distance between the two side locating pins: 81 mm measured from the outer edge of one pin to the outer edge of the other pin
- locating pin diameter: 3 mm each
- therefore, the centre-to-centre distance between the locating pins is 78 mm
- diameter of the central mounting screw: 4 mm
- position of the mounting screw: centred between the two locating pins

If the spacing of the locating pins matches, this specimen holder can also be mounted on microscope stages made by other manufacturers.

Leitz Wetzlar produced specimen holders with fixed stage clips as well as versions with a spring-loaded stage clip. Here I am showing and offering the spring-loaded version.

On the used market and in technical documentation, this microscope part is described using a variety of names. Common terms include:
- specimen holder
- microscope stage specimen holder
- mechanical stage specimen holder
- slide holder
- microscope slide holder
- microscope slide clamp
- spring-loaded specimen holder
- spring-loaded slide holder
- spring-loaded stage clip
- specimen clamp
- specimen carrier
- mechanical stage carrier
- XY stage specimen holder
- specimen holder for mechanical XY microscope stage
- stage holder
- stage clip assembly

The photographs in the gallery show the exact dimensions of the microscope part offered here. In addition, the last photograph includes an arrow indicating exactly which microscope part is being described and where it is mounted on the mechanical XY microscope stage, making identification straightforward. The accompanying video demonstrates the operation of the spring-loaded stage clip.

What is this part needed for?

• if you have a stage that is missing the specimen holder
• if you have a "simple" specimen holder and want to replace it with one with a spring-loaded clamp
• if you want to install this holder on a stage in a microscope from another manufacturer

This is description of this part:

Complete manipulator of the mechanical XY stage for Leitz Wetzlar microscopes.

This is a complete control assembly for the mechanical microscope stage, allowing precise movement of the specimen in both the X and Y axes of the stage plane. The manipulator consists of two coaxial knobs, two independent drive shafts and the fixing elements that attach it to the stage mechanism.

This particular manipulator was removed from a Leitz Dialux microscope. The last photograph in the gallery shows the entire microscope stage from which it was dismounted. The manufacturer also used the same or very similar stages in many other Leitz Wetzlar microscope models, which is why the manipulator may also be compatible with other models from this company.

On the second-hand market and in service documentation one encounters many names referring to this assembly. The most commonly used terms include, among others:
- stage manipulator
- XY stage manipulator
- mechanical stage drive
- stage control knobs
- specimen mover
- coaxial stage drive
- stage drive assembly
- mechanical stage control
- manual XY stage drive
- stage actuator mechanism

Such manipulators very often suffer mechanical damage during transport of the microscope. Because they protrude beyond the outline of the stand, it is precisely they that absorb the impact energy first - in the event of a fall or improper packaging of the instrument.

In many cases it is not the entire manipulator that is damaged, but only one of its components. Most often these are the knobs, the drive shafts, the coaxial sleeves or the fixing elements. For this reason, this database also contains all the most important constituent parts of this (and other) manipulators, offered separately as service elements.

Damage to the manipulator does not make further work with the microscope impossible. The specimen can be moved by hand, or a simple specimen holder without an XY movement mechanism can be fitted. Such a solution works well at low magnifications; however, when working with objectives of magnifications greater than 40x (e.g. 60x, 63x, 80x or 100x), precise manual movement of the specimen becomes very difficult. At total magnifications exceeding about 400x, even a slight movement of the hand shifts the image by a considerable distance within the field of view. The mechanical manipulator enables very smooth, controlled and repeatable movement of the specimen in both axes, which is particularly important during observation with oil immersion and when producing photographic documentation.

The photographs in the gallery show the exact dimensions of the complete manipulator. The last photograph presents the entire microscope stage together with an arrow indicating the mounting location of this element, which makes it possible to identify the offered part unambiguously.

What is this part needed for?

• if you have an incomplete Leitz microscope stage in which this manipulator is missing (e.g. someone did not finish the repair)
• if you have a Leitz microscope stage in which the manipulator does not work or is of very poor quality (it turns stiffly or unevenly)
• if you need a precise coaxial mechanism for your own DIY project, e.g. related to macro photography or rotating an object for 3D films

LOMO СЛ1/4λ (Latin alphabet transcription: SL1/4lambda) Quarter-wave plate - Sénarmont variant (CP-QS - Compensating Plate, Quarter-wave Sénarmont), perpendicular/parallel axis - for Lomo Polam polarizing microscopes

Lomo microscope compensating slider:
Factory marking: СЛ1/4λ (Latin alphabet transcription: SL1/4lambda)
Alternative name: Sénarmont, CP-QS (Compensating Plate, Quarter-wave Sénarmont)
Crystal material: Mica
Optical retardation: 1/4 lambda (approx. 140 nm)
Orientation of optical axes: perpendicular and parallel to the slider body edge

Dimensions:
Total length: 80 mm
Insertion length: 60 mm
Width: 19 mm
Height: 7,5 mm

Quarter-wave compensating slider of the Sénarmont type (Sénarmont quarter-wave plate) introducing a phase shift of 1/4 wavelength. Unlike the standard quarter-wave plate, in the Sénarmont configuration the crystal axis (Ng) runs parallel to the vibration direction of the polarizer, and the 45-degree effect is enforced by the microscope accessory slot - not by the orientation of the crystal within the body. Used for precise quantitative measurements of optical retardation, determination of the optical sign of minerals, and analysis of elliptically polarized light - in combination with a rotating analyzer and an interference filter (typically 546 nm or 551 nm).

The axes of the fast ray (Np) and slow ray (Ng) are oriented parallel and perpendicular to the edges of the slider body. This arrangement is used in specific types of LOMO microscope heads or with a non-standard (rotated by 45 degrees) polarizer setup, in order to achieve the correct interference effect.

A first variant of this slider is also available - standard quarter-wave plate СЛ1/4λ (Latin alphabet transcription: SL1/4lambda) with diagonal axis (45 degrees), suitable for the vast majority of classic polarizing microscopes with a standard accessory slot. Before purchasing, please check the design of your microscope. Using the incorrect variant will cause the crystal axes to misalign with the vibration direction of the polarized light, preventing proper background extinction as well as precise measurements and conoscopic observations.

What is this part needed for?

• If you have a polarizing microscope and you are missing this compensator on the slider

Intermediate tube with an iris diaphragm slide slot connecting the illuminator to the microscope body of the Lomo MMU-3 metallurgical microscope.

This microscope part is an intermediate tube located in the optical path between the reflected-light illuminator with its condenser and the microscope body. It performs two functions:
- on one side it is attached to the microscope body, and this side contains the slot into which the iris diaphragm slide is inserted
- on the opposite side there is a dovetail mount for the illuminator assembly

Please note:
- the original Cyrillic designation of this model is: ЛОМО ММУ-3
- for users of the Latin alphabet who know that the manufacturer is "Lomo", the designation looks like: Lomo MMY-3
- however, the original designation is read as: Lomo MMU-3

The last photograph shows this microscope part indicated with an arrow and its exact position inside the microscope, allowing it to be identified unambiguously.

What is this part needed for?

• if you have a Lomo MMU-3 microscope body without this component
• if you already have this component but it is incomplete, damaged or in poor condition

This is description of this part:

Paraboloidal darkfield condenser for the vintage Stativo Euskop microscope manufactured by the Italian company Officine Galileo.

Basic parameters:
Mounting method: below the microscope stage in the circular condenser holder
Mounting diameter: 37 mm
Condenser type: paraboloidal condenser
Iris diaphragm: yes (this is an uncommon feature in darkfield condensers)
Oil immersion: yes, the condenser was designed for cedarwood oil
Numerical aperture N.A.: not specified (however, since this is an oil-immersion condenser, its N.A. is greater than 1.0)
Additional information: the light refraction was calculated for a microscope slide glass thickness of 1.35 mm
Manufacturer's original name: condensatore per campo oscuro

The photographs in the gallery show that one retaining pin securing one iris diaphragm leaf is no longer in its original position. In order to preserve the historical condition of this vintage condenser, this detail has intentionally not been repaired. This minor defect does not affect the operation of the iris diaphragm, which can be clearly seen in the accompanying video.

The website "Museo di Storia della Psichiatria" (https://bbcc.regione.emilia-romagna.it), dedicated to the cultural heritage of the Italian region of Emilia-Romagna, provides a downloadable PDF museum record describing an identical condenser preserved in the museum's collection (https://bbcc.regione.emilia-romagna.it/samira/api/print/card/173420).

What is this part needed for?

• if you own an Officine Galileo Stativo Euskop microscope and would like to obtain an original darkfield condenser for it
• if you collect historic microscope optics
• if you simply want to use this condenser, as it is a fully functional example with a mounting diameter of 37 mm

This is description of this part:

The interchangeable single objective holder for Lomo Polam series polarizing microscopes allows a single objective to be installed in place of the standard objective nosepiece.

This holder is compatible with the following polarizing microscopes:
- Lomo Polam L-211
- Lomo Polam L-213
- Lomo Polam LMPR

The microscope models listed above are equipped with a removable 5-position objective nosepiece that can be removed and replaced with this single objective holder. A single-objective configuration has long been a standard solution in polarizing microscopy, and many users still prefer it today.

Simpler models, such as the Lomo Polam C-111 (Latin transcription S-111) and P-111 (Latin transcription R-111), do not have a removable objective nosepiece. Therefore, this holder is not compatible with those models.

Important:
The objective is not screwed directly into this holder. This holder does not have an RMS thread. It accepts objectives that have already been mounted in dedicated centering adapters. These adapters provide the precise objective centering required for polarizing microscopy.

The manufacturer illustrates this holder in Figure 4 of the instruction manual (item 47) and refers to it as щипцовое устройство (shchipcovoe ustrojstvo - pincer device).

Several names are commonly used for this component in documentation and among microscope users, including:
- single objective holder
- single objective mount
- objective holder
- objective clamp
- objective carrier
- pincer holder
- single objective nosepiece
- objective socket
- the English term "single objective microscope nosepiece" is very commonly used, even though it is technically associated with a revolving nosepiece

If you need additional comparison photographs, this database also contains:
- the 5-position objective nosepiece for this microscope model (part number 00798)
- the centering adapter for a single RMS objective (supplied together with the objective as part number 00772)

What is this part needed for?

• if you have a Lomo Polam microscope without any turret
• if your turret or single-objective-holder is damaged
• if you need an additional microscope objective holder

This is description of this part:

Dust protection end caps for the eyepiece tubes of PZO stereo microscopes and colposcopes.

These end caps are designed to protect empty eyepiece tubes whenever the eyepieces are removed for transport or storage inside the wooden carrying case. Installing the caps prevents dust from entering the microscope head and reaching the internal prisms.

The offer applies to 2 (two) pieces, i.e. one pair. Each individual end cap features the original PZO logo.

These end caps fit stereo microscopes from any manufacturer, provided they use eyepieces with a mounting diameter of 34 mm:
- PZO MST-1 / MST-2
- PZO MST-130 / MST-131 / MST-132
- PZO MST ZOOM
- PZO KLP-21 / KLP-22 colposcopes
- DIY devices (e.g. queen bee insemination equipment) built using PZO MST stereo microscopes
- Meopta DM23
- Carl Zeiss Jena Stemi SM XX (the so-called SM-20)
- medical optical instruments (e.g. ophthalmic slit lamps) manufactured by Carl Zeiss Jena and based on the SM-xx stereo microscope platform

These end caps do not fit microscopes using eyepieces with diameters other than 34 mm:
- they do not fit PZO MST-110 / MST-127 stereo microscopes because these use 23.2 mm eyepieces
- they do not fit Lomo MBC-1 / MBC-2 stereo microscopes because these use 30 mm eyepieces
- they do not fit Lomo MBC-9 / MBC-10 stereo microscopes because these use 32 mm eyepieces
- they do not fit Carl Zeiss Jena Technival / Citoval stereo microscopes because these use 23.2 mm eyepieces
- they do not fit Carl Zeiss West Germany stereo microscopes because these use 30 mm eyepieces
- they do not fit Euromex E-series and Z-series stereo microscopes because these use 30.5 mm eyepieces
- they do not fit Hertel & REUSS STE-series stereo microscopes because these use 31 mm eyepieces

The FAQ section of this database explains that these are genuine original parts rather than 3D-printed reproductions. It is worth repeating here: these are original vintage PZO plastic end caps. They are not generic "no-name" caps and they are not DIY parts made on a 3D printer.

The last photographs in the gallery show an example of these end caps installed on the head of a PZO MST-130 stereo microscope.

Hard plastic eyecups (not soft rubber eyecups) for PZO microscope eyepieces with a 23.2 mm mounting diameter.

These eyecups are fitted onto microscope eyepieces and serve two main purposes:
- they allow the user to comfortably rest their head against the eyepieces, reducing neck strain during prolonged microscope work (this is not possible with soft rubber eyecups)
- they block stray light entering from the sides, reducing reflections and improving image contrast

This offer includes 2 (two) pieces, i.e. one pair.

A few quick facts:

This is description of this part:

Microscope body of the Lomo Polam R-113 polarizing microscope (the original Cyrillic designation is ЛОМО Полам Р-113).

The body includes:
- the base with the illuminator mount
- the arm containing the coarse focus (macro movement) and coaxial fine focus (micro movement) mechanism
- a pincer holder (single objective holder) for a polarizing microscope objective
- the microscope head mount - however, in Lomo Polam microscopes this position is first occupied by the intermediate tube with the polarization analyzer, and only then by the microscope head

The complete Lomo Polam R-113 / P-113 microscope body may be useful in the following situations:
- if you are building your own microscope by purchasing individual parts to assemble a configuration that fully meets your requirements
- if you own a Lomo Polam microscope but its body is heavily worn, damaged or incomplete, for example with defective coarse/fine focus controls, a damaged pincer objective holder or other mechanical problems

Lomo Polam microscopes are built around a standardized modular design. For example:
- components such as the stage holder, condenser holder, polarizing intermediate tube, monocular head or trinocular photo head from other Polam models (e.g. L-211 or L-213) are compatible with the R-113 / P-113 body
- the R-113 body can also be installed on other, including newer, Lomo Polam models, making it an inexpensive way to repair a microscope with a defective coarse/fine focus mechanism

What is this part needed for?

• for people assembling their own microscope from individually purchased components
• for people who need to replace a poor quality stand with a properly functioning one
• other situations in which such a microscope stand may be required are listed in the description

Microscope stage holder for:
- Reichert Austria Zetopan
- Reichert Austria Neozet

Information from the manufacturer's English-language catalogue "Zetopan Research Microscope. Price List, Effective December 1, 1976":
- This component belongs to the microscope stage. The catalogue number of the stage is: 9 90 00 02 (or Pol-stage 9 19 46 02)

The photo gallery contains detailed photographs of this part together with its dimensions.

This component is attached to the microscope body by means of a clamping screw (a so-called "quick-release clamp"), which locks onto the vertical dovetail guide of the microscope body. The microscope stage itself is then bolted to the top of this holder. In other words, the stage is permanently attached to the holder, while the complete holder-and-stage assembly can be removed from the microscope within seconds.

This allows users who own several microscope stages (for example a standard XY stage, a circular polarizing stage or a sliding stage for reflected-light EPI observation) to mount each stage permanently on its own holder and quickly interchange complete stage assemblies on the same microscope.

What is this part needed for?

• as a repair part by replacing the entire damaged element
• if you have a microscope stage where this element still works but is of very poor quality
• if you have a single Reichert Zetopan microscope but multiple microscope stages and want to swap them quickly

This is description of this part:

Complete microscope condenser holder assembly with centering screws, toothed rack and focusing knob for the Reichert Austria Zetopan microscope.

This module consists of the following components:
- guide rail into which the condenser slides
- two condenser centering screws
- clamping mechanism that secures the entire module to the dovetail guide in the microscope body
- focusing knob for moving the condenser vertically
- toothed rack (often incorrectly referred to as a gear)
- note the round opening near the dovetail mounting point - it provides a passage for the light beam leading to an optional EPI illuminator

Any of the components listed above may become damaged during the lifetime of the microscope. In such cases, either the damaged component or the complete condenser holder assembly must be replaced.

The purpose of this microscope part is to hold the microscope condenser and allow it to move vertically.
The module is attached with a clamping screw (the so-called "quick-release clamp") to the vertical dovetail guide in the microscope body. The microscope stage holder is mounted on the same guide, above this module.

This is description of this part:

Body of the Lomo Polam L-211 polarizing microscope (the original Cyrillic designation is ЛОМО Полам Л-211).

The body includes:
- the base with a mounting point for the large illuminator attached to the rear of the microscope
- a built-in right-angle mirror in the base that redirects the light beam. This mirror can be centered using two adjustment screws located on the front of the microscope base
- the focusing block with coarse focus (macro movement) and coaxial fine focus (micro movement)
- a mount for either the single objective holder (pincer holder) or the 5-position polarizing objective nosepiece
- the microscope head mounting point - however, in Lomo Polam microscopes a polarizing intermediate tube with the analyzer is mounted here first, followed by the microscope head

The complete body of the Lomo Polam L-211 microscope may be useful in the following situations:
- if you are building your own microscope by purchasing individual components to assemble a configuration that perfectly matches your requirements
- if you own a Lomo Polam microscope whose body is in very poor condition, damaged or incomplete, for example with non-functioning focusing controls, a damaged illuminator mount or other mechanical problems

Since this database includes both the body of the Lomo Polam R-113 (Полам Р-113) and the Lomo Polam L-211 (Полам Л-211), here is a brief summary of the differences between them:
- the Lomo Polam R-113 has no built-in illumination components in the base, only an opening for a mirror or an external light source
- the Lomo Polam L-211 has a built-in right-angle mirror in the base that redirects light from the rear illuminator vertically upward, and it also provides a mounting point for the large rear illuminator
- the Lomo Polam R-113 has a permanently installed single objective holder (pincer holder) for a polarizing objective
- the Lomo Polam L-211, on the other hand, has an interchangeable mount that accepts either a single objective holder (pincer holder) or a 5-position polarizing objective nosepiece

Lomo Polam microscopes feature a standardized modular design, which means, for example:
- components such as the microscope stage holder, condenser holder, polarizing intermediate tube, monocular head or trinocular photo head from other Polam microscope models (e.g. R-113, R-211 or L-213) are compatible with this L-211 body
- this L-211 body can also be installed on other Lomo Polam models, including older ones, making it an inexpensive way to upgrade an older Polam microscope, for example one with a damaged coarse/fine focusing block
- another interesting option is replacing only the base in order to equip simpler Lomo Polam microscopes with the powerful rear-mounted illuminator

An amusing curiosity. Users of Lomo Polam microscopes, especially those unfamiliar with the Cyrillic alphabet, sometimes misread the model designation of the Lomo Polam L-211.
- the original Cyrillic designation is: Л-211
- many users mistake the letter "Л" (L) for the letter "П" (P) because they have a very similar appearance in Cyrillic
- as a result, they incorrectly read the model designation as Lomo Polam P-211
- the funny part is that there actually is a microscope model called "ЛОМО Полам Р-211" - however, the Cyrillic letter "Р" corresponds to the Latin letter "R", which makes the confusion even greater

What is this part needed for?

• for people assembling their own microscope from individually purchased components
• for people who need to replace a poor quality stand with a properly functioning one

This is description of this part:

Intermediate tube with trinocular/photo port, objective nosepiece dovetail mount, Bertrand lens and POL analyzer slot for the Reichert Zetopan microscope.

This is the intermediate tube, forming the main optical module of the microscope. It is mounted onto the microscope stand, while the binocular viewing head is then attached to the top of this intermediate tube. The module incorporates the following components:
- a third optical path (photo port), which is why this module is sometimes referred to as a trinocular unit
- a Bertrand lens (indicating that this is the newer version of this intermediate tube), with a control knob for inserting the lens into the optical path
- a dovetail mount for the objective nosepiece together with a clamping screw for securing the nosepiece
- slots for sliding inserts, including a polarizing analyzer

In addition, the entire module rotates smoothly. Because of its complex mechanical and optical design, it is a component in which individual internal parts may occasionally become damaged.

Information from the manufacturer's English-language catalogue "Zetopan Research Microscope. Price List, Effective December 1, 1976":
- This component belongs to the microscope stand. The catalogue number of the stand is: 9 90 00 01
- English name of this component: swing-out tube carrier, deviating prism for observation and photomicrography, swing-out Bertrand lens

Over the years, Reichert manufactured Zetopan microscopes in three different colours: black, silver and cream. The intermediate tube offered here is the silver version. The different versions differ only in colour and can be exchanged between Reichert Zetopan microscopes. This means that this silver intermediate tube can be fitted to a black Zetopan microscope, although the colour combination may not be aesthetically pleasing.

What is this part needed for?

• as a replacement part for repairing a Reichert Zetopan microscope by replacing the entire damaged intermediate fototubus assembly
• if you have a Reichert Zetopan microscope in which this module still functions but is in very poor condition
• if one of the components of the intermediate tube has been damaged

This is description of this part:

Replacement part for an HBO / Hg 100W fluorescence illuminator used with Nikon Optiphot microscopes and other microscope models equipped with an illuminator of the same mechanical design.

This is the spherical rear reflector mounted inside the fluorescence illuminator behind the lamp. Its function is to collect and reflect the light that is emitted backwards and would otherwise be lost, directing it towards the collimating lens.

This particular reflector was removed from a fluorescence illuminator used on a Nikon Optiphot microscope. Hg 100W / HBO 100W illuminators of this type, or mechanically identical versions using the same rear reflector, were fitted to, among others:
- Nikon Optiphot
- Nikon Labophot
- Nikon Microphot

Therefore, the reflector presented here is also compatible with these microscopes. However, it should primarily be regarded as a replacement part for the fluorescence illuminator rather than for a specific microscope model.

When may the rear reflector need to be replaced?
- High-pressure fluorescence lamps used as the light source in these illuminators may explode, damaging the rear reflector and often the collimating lens as well.
- In addition, because the reflector is located immediately next to the light source, it is exposed to very high temperatures and is therefore susceptible to thermal damage.
- Another common issue is oxidation of the reflective surface over the course of decades. When this happens, the reflector loses its optical performance and the entire illuminator produces significantly less light.

Important: Nikon EPI fluorescence illuminators of that period were manufactured in several different lamp house versions. They are most commonly referred to simply as:
- Nikon Hg 100W
- Nikon HBO 100W
- Nikon HBO 100W HG Lamp House
- often the model is Nikon LH-M100CB-1

For confirmation of compatibility, the photo gallery includes precise dimensions of this component. The last photograph also shows the complete illuminator from which this reflector was removed, allowing compatibility to be verified with confidence.

What is this part needed for?

• as a service part (repair component) if you own a microscope equipped with this illuminator and this part has been damaged

This is description of this part:

Replacement optical component for the HBO / Hg 100W fluorescence illuminator used with Nikon Optiphot microscopes and other microscope models equipped with this type of lamp house.

This is the illumination collector lens combined with a heat absorbing filter that absorbs the heat generated by the light source (mercury arc lamp).

This particular collector lens and heat absorbing filter assembly was installed in a fluorescence illuminator used on a Nikon Optiphot microscope. Hg 100W / HBO 100W illuminators, or similar models with the same mechanical design and identical optics, were used in, among others, the following microscopes:
- Nikon Optiphot
- Nikon Labophot
- Nikon Microphot

Therefore, the optical module offered here is also compatible with these microscopes. First and foremost, it is a replacement part for repairing the illuminator rather than a specific microscope.

When may it become necessary to replace the heat absorbing filter or the collector lens that collimates the light beam?
- the high-pressure mercury arc lamps used as the light source in these illuminators may explode, damaging the rear reflector and often also the collimator lens.
- in addition, the collector lens located immediately next to the light source is particularly susceptible to damage due to prolonged exposure to high temperatures.
- another very common failure is that the filter simply cracks because of mechanical damage (although it is mounted without mechanical stress - it is intentionally fitted with slight clearance).

Important: Nikon EPI fluorescence illuminators from that period were manufactured with several different lamp house designs. They are most commonly referred to simply as:
- Nikon Hg 100W
- Nikon HBO 100W
- Nikon HBO 100W HG Lamp House
- often the model is Nikon LH-M100CB-1

For verification, the photo gallery includes precise dimensions of this microscope part. The last photograph also shows the complete illuminator from which this microscope part was removed, allowing compatibility to be confirmed with certainty.
