It may be interesting to note that this transport case was manufactured in 1977 and is still in excellent condition!

This type of wooden storage case is very often used for storing other microscope models, not only those made by PZO.

Very important: this wooden case does not fit the PZO Biolar microscope. Very often PZO Biolar and PZO Studar microscopes are confused with each other. If you want to identify your PZO microscope model - contact us.

On the market, many different names are used for a wooden case for a microscope. These include:
- wooden case
- wooden box
- wooden crate
- wooden housing
- microscope case
- transport case
- transport box
- storage case
- carrying case

Tube length: infinity
Thread: M25
Cover glass: not required, may be present or not
Immersion: no

This objective fits, among others, the following microscopes:
- Carl Zeiss Jena Jenamed
- Carl Zeiss Jena Jenalab
- Carl Zeiss Jena Jenaval
- Carl Zeiss Jena Jenalumar

For the Carl Zeiss Jena Jenamed microscope, this objective fits every variant:
- Carl Zeiss Jena Jenamed variant

tube.
Application: Zeiss Axio microscopes, second series
Manufacturer number: 425503-9901-000
Light split: 0/100 and 100/0

This trinocular photo tube contains a Zeiss infinity correction tube lens 425308-0000-000.

Parameters of the Zeiss 425308 lens:
Lens type: correction lens (en: infinity corrected tube lens)
Magnification: none (i.e. 1x)
Wavelength range: 380 - 700 nm
Diameter: 40 mm
Length: 12.8 mm
Thread: M36 x 0.75

The Zeiss tube lens 425308-0000-000 is required to use infinity-corrected Zeiss microscope objectives on microscopes from other manufacturers - including those designed for 160 mm tube length. It is also very often used in super macro photography to connect infinity-corrected objectives to a camera.

This element can be a solution to the following issues:
- How to repair or replace the prism in the Zeiss 425503 photo tube?
- What to do in case of prism delamination in the Zeiss 425503 head?
- Repair of a mechanically damaged Zeiss 425503 trinocular tube
- What to do if the Zeiss "tube lens" 425308 is damaged, scratched, or of poor quality?
- Can Zeiss objectives be used on microscopes from other manufacturers?
- Can infinity-corrected objectives be used on a 160 mm microscope?
- How to take super macro photos using infinity-corrected microscope objectives?

And once again at the end: carefully look at the photos. Note that this trinocular (photo tube) does not include a binocular eyepiece head.

holder into which a round filter with a diameter of 32 mm can be inserted
- the hinged, tilting cover allows the light output to be completely blocked

This slide-in element is used in the following microscopes:
- Carl Zeiss Jena Jenaval
- Carl Zeiss Jena Jenalumar
- Carl Zeiss Jena Jenavert

Cast or injection-molded metal parts of Carl Zeiss Jena carry their own numbers. This microscope element bears the numbers 2645 (full designation: Si10 2645) and 2683 (full designation: Si10 CZ 2683).

By default, in the basic versions of the CZJ Jenaval microscope, a simpler version of this element is installed - only a slide with a filter holder, without a light blocking cover.

In models with EPI illumination (de: Auflicht), such as Carl Zeiss Jena Jenavert and Carl Zeiss Jena Jenalumar, the transmitted light illuminator cover allows the transmitted light to be completely shut off when working exclusively with EPI illumination.

In the last photo in the gallery, the exact location of this element in the microscope is indicated with an arrow. This allows you to identify it precisely.

Manufacturer: Lomo
Magnification: 20x
Model: 20 0.40 P
Numerical aperture: 0.40
Tube length: 160 mm
Focal length: 33 mm
Cover glass: yes, 0.17 mm
Thread: RMS + Pol adapter
Info: P = Polarization

This is an objective designed for transmitted light work with a cover glass.

The RMS thread objective is mounted on a dedicated slide-in adapter that allows it to be used in Lomo MIN series and Lomo Polam series microscopes. Of course, the objective can be unscrewed and another objective can be mounted in the adapter.

The objective itself, once removed from the adapter, is a standard objective that can be used in virtually any microscope with an RMS thread. It is a so-called "short objective" (focal length 33 mm). When a 12 mm adapter is added, the total length becomes 45 mm, allowing it to be used with newer microscopes from any manufacturer.

Lomo polarization objectives with RMS thread can be installed in an RMS-M27 adapter and then used in microscopes such as Lomo Biolam M, Lomo Biolam I, Lomo Lumam, or Lomo ML-2. I have also frequently seen such objectives used in Zeiss Axio series microscopes with M27 thread.

The Pol adapter also allows precise centering of the objective relative to the entire optical path - this requires tools (keys / tools).

Info: I have repeatedly seen information stating that this RMS-Pol adapter is compatible with Leitz Wetzlar polarization microscopes - however, I have not personally verified this.

In summary, this objective is dedicated to Lomo MIN-1, MIN-4, MIN-5, MIN-6, MIN-8, Lomo Polam R-113, Polam L-211, Polam L-213, Polam R-311, Polam LMPR microscopes - but it is practically compatible with any microscope from any manufacturer that supports 160 mm objectives.

Note - this model of microscope objective is very often used for macro photography and focus stacking. More information on this can be found at the end of this description.

Additionally, this objective is very often used for macro photography even without a microscope. This objective does not require a cover glass and works in the "direct-projection" technique, meaning it can be connected directly to a camera without additional optics. This allows achieving a very high magnification scale and great depth of field across the entire image when using focus stacking. The fact that this is a polarization objective (i.e. stress-free optics without internal glass tensions) further improves image quality at high magnifications.

Light source connector diameter: 15 mm
Manufacturer catalog number: 10450398
Compatibility: the 15 mm connector fits light sources from Schott, Leica, Dolan-Jenner and other manufacturers using this standard

This element is used to transmit light through a fiber optic cable from a light source (illuminator) to a microscope XY stage. Such a stage is then used for transmitted light observation. A setup consisting of a light source - fiber optic light ring - XY stage was used for example in Leica DVM systems or in motorized Märzhäuser / Prior stages used in many microscopes, for example the Leica DM6000 microscope. This is a fiber optic light ring for a stage - not for one specific microscope, because such an illuminated stage can be mounted to various microscopes.

The Leica 10450398 fiber optic light ring with 15 mm connector can be used with the following light sources among others:
- Dolan-Jenner MI-150

is part of the component shown in the Leitz Dialux 20 microscope manual under number 18, which corresponds to the field diaphragm assembly. This page from the manual can be found in the image gallery.

The field diaphragm of the Leitz Dialux 20 microscope consists of:
- lens
- iris diaphragm
and is screwed to the microscope base (stativ foot) directly below the condenser.
The item offered here is exactly this lens.

This lens performs several functions:
- it collimates the light beam
- it protects the iris diaphragm from contamination
- it also serves as a filter holder for inserting filters

It is worth noting that this element may also be compatible with many other Leitz Wetzlar microscope models.

The mirror is in excellent condition - however, in my opinion it is attached in an unusual way. Either the manufacturer used a large amount of adhesive to secure it properly - or somebody did this later during the years of use using a large amount of adhesive. Of course this has no effect on operation - operation is flawless - but I want to point this out.

meaning the shaft with focusing knobs mounted on both ends on the sides of the microscope. Part of this shaft contains a toothed rack, or more precisely speaking, it is a toothed shaft. In the item shown and offered here, the fine focus knob (micro focus) is mounted on the left end of the shaft. Please note that the left and right knobs are identical - however, screws of different lengths are used to attach them: the left knob is attached with a 12 mm screw, while the right knob uses a 16 mm screw. Detailed information about the screws used to attach the coarse and fine focus knobs can be found here: https://www.facebook.com/MikroskopyPZO/posts/pfbid0x2tFPHAEqjn4B7BRsvm2vAt9yyuuSM836QS6K4951GqeUFpU2FJH8YXfFFxbz3cPl

Such focus shafts are used in the following microscopes:
- Carl Zeiss Jena Ergaval
- Carl Zeiss Jena Amplival (and its variants: Fluoval, Epival, Vertival, Interphako)
- Carl Zeiss Jena Metaval
- Carl Zeiss Jena Docuval

This coarse and fine focus shaft may help solve the following problems in Carl Zeiss Jena Ergaval / Amplival microscopes and related models:
- if the shaft became bent, causing a noticeable jump while rotating it (a very common failure)
- if the screw holding the fine focus knob broke off or snapped, leaving part of the screw inside the shaft
- if the left fine focus knob is missing or damaged
- if the thread on the right or left end of the shaft, where the fine focus knobs are attached, is damaged
- if the toothed rack on the shaft (because such a shaft is effectively a toothed shaft) becomes damaged

for taking microscope photographs or recording microscope videos. This is a gray photographic adapter.

Basic technical parameters:
- mounting connection to microscope stand: 41 mm dovetail
- output connection type on the photo port: 49 mm internal thread
- connection for binocular head mounting: Jena standard 41 mm dovetail
- magnification directed to the binocular head: 1.6x
- magnification on the photo output: none (that is 1.0x)

Because this photo head has a 49 mm threaded output, virtually any device, camera, adapter, tube or other accessory can be connected after using an appropriate 49 mm thread adapter. Direct projection technique may be used (because there is no additional optics inside), or any projection eyepieces may be installed in the optical path.

This photographic attachment is intended mainly (but not exclusively) for the following microscope models:
- Carl Zeiss Jena Eduval
- Carl Zeiss Jena Laboval
- Carl Zeiss Jena Ergaval
- Carl Zeiss Jena Amplival
- Carl Zeiss Jena Vertival
- Carl Zeiss Jena Epival
- Carl Zeiss Jena Metaval
- Carl Zeiss Jena Telaval
- Carl Zeiss Jena Pictoval
- Carl Zeiss Jena Epignost

The list above contains Mikroval series microscopes with gray housings - just like the tube shown and offered here. However, it also works with older black Carl Zeiss Jena microscopes:
- Carl Zeiss Jena L-Stativ (models Lg, Lu and Lr)
- Carl Zeiss Jena Lumipan
- Carl Zeiss Jena Ng
- Carl Zeiss Jena Nf (and NfPk)

Please note that microscopes from other manufacturers also use the 41 / 41.5 mm dovetail connection standard. Because of this, this photographic head can also be used with microscopes made by:
- Lomo (for example Lomo Biolam)
- Meopta
- IOR
- selected Reichert microscopes (for example Reichert Neozet)
- Will Wetzlar
- Hund Wetzlar
- Leitz Wetzlar

This Carl Zeiss Jena tube is also very often used with microscopes having a larger head mounting diameter. In such cases users apply additional spacer or thickening rings. Because of this, this photo adapter also fits microscopes from manufacturers such as:
- PZO (for example the PZO Biolar model with 43 mm connection)
- Olympus (for example the Olympus CH model with 42 mm connection)

The element that allows a photographic camera or imaging camera to be connected to Carl Zeiss Jena Mikroval series microscopes may be referred to by different names. Commonly used names include:
- trino head
- trinocular head
- photo head
- photographic head
- photo attachment
- photographic attachment
- photo adapter
- photographic adapter
- photo tube
- photographic tube
- phototube
- photographic angle tube
- and various combinations of the words head, attachment, adapter or tube with terms such as photo, photographic, for camera and similar

This element is used when the microscope does not have a transmitted light illuminator with a lamp holder installed in the rear part of the base. In such a case, so that there is no open hole and no contamination can enter the inside of the microscope, this opening can be closed with this blanking plug.
When can such a situation occur that the microscope does not have a transmitted light illuminator? Most often when the microscope is intended for reflected light work only and simply does not have any DIA illuminator (transmitted light illuminator).

This element fits the following microscopes:
- Carl Zeiss Jena Ergaval
- Carl Zeiss Jena Amplival
- Carl Zeiss Jena Epival
- Carl Zeiss Jena Vertival
- Carl Zeiss Jena Interphako
- Carl Zeiss Jena Fluoval

and related models.

This element is used when transmitted light is temporarily not needed. The illuminator itself does not need to be removed - instead, the light output should simply be completely blocked, and this light output is the collector lens itself. This collector lens is located inside the microscope base, above the angle mirror and below the condenser.

When can there be a need to completely block transmitted light? Most often when:
- a microscope with DIA illumination (transmitted light) and EPI illumination (reflected light) is available, but temporarily only reflected light operation is needed
- a microscope previously working with transmitted light (for example Carl Zeiss Jena Amplival) is being converted into a microscope intended to work permanently only with reflected light (for example converting an Amplival into a Vertival)
- for example a Fluoval microscope is used and it is undesirable that "the lower light is visible"

This element fits the following microscopes:
- Carl Zeiss Jena Ergaval

special diaphragms was supplied. The set included phase contrast diaphragms and dark field diaphragms.

Note - I am showing and offering here one single diaphragm in holder - exactly the one visible in the photos. This is a phase contrast diaphragm (phase annulus). The complete set for the Lomo Polam microscope contains 5 diaphragms.

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

The newest version of the Lomo Polam microscope, namely the Lomo Polam LMPR model, no longer requires this accessory. The Lomo Polam LMPR already has a special polarizing phase contrast disc condenser (somewhat similar to the Lomo KF-4 condenser).

In the last photo in the gallery you can see a page from the Lomo Polam microscope manual where this element is shown. In the manual it is shown in figure number 6, element number 65.

this component will also fit the photographic trinocular head of the following macroscope models:
- Wild M400
- Wild M450 (another name: Leica M450)

By MISTAKE I wrote an "L" (as in "left") on this element. In reality this is a RIGHT prism, so please do not be misled by the letter visible in the photos. I repeat: this is a right prism.

The prism is attached to the thread onto which the eyepiece tube is screwed. At present this forms one combined assembly.
If you would like to see this thread in more detail - it is available in the database under number 99401.

This service component may solve the following problems with the trinocular head of the Wild Heerbrugg / Leica M450 macroscope:
- how to remove fungus from the prism?
- can delamination on the prism of the Wild M420 head be removed?
- is it possible to repair the mirror in the prism if it has oxidized?
- cracked prism in the head of the Leica M420 macroscope

The macroscope is an advanced stereoscopic microscope with a high-resolution ZOOM objective.

Why are dual names Wild and Leica used? The M400 macroscope was manufactured by Wild Heerbrugg (Switzerland). Later, the Wild company was acquired by Leica and the M420 and M450 models may be labeled either Wild M420 / Wild M450 or Leica M420 / Leica M450. Note: this is different for the Wild M400 model - it does not have a Leica equivalent, because "Leica M400" is a model of a surgical microscope.

- Model: 5/0.15 160/-
- Alternative model marking: 5/0.15 160/0
- Magnification: 5x
- Numerical aperture N.A.: 0.15
- Correction: achromatic
- Focal length FL: 33 mm
- Tube length: 160 mm
- Cover glass: not required, but may be used
- Immersion: no (dry objective)
- Thread: RMS

This model has a metal housing with no lens at its end. Additionally, this housing can be unscrewed without affecting the operation of the objective - resulting in a relatively large working distance of more than 20 mm.

Three features:
- large working distance exceeding 20 mm
- exceptionally high numerical aperture N.A. of 0.15
- achromatic correction allowing direct projection use
make this relatively uncommon model very frequently chosen for macro photography using a microscope objective connected to a camera (focus stacking).

The fact that this objective has FL = 33 mm allows it to be used with microscopes from other manufacturers, including:
- Lomo Biolam
- Lomo MBB-1A
- Carl Zeiss Jena LG / Lu / Lumipan
- Carl Zeiss Jena Nf
- Olympus CH

Note! Please note that the FL = 33 mm focal length means that this objective DOES NOT FIT the following microscopes:

Early versions of this objective (with low serial numbers) have the engraved marking 5/0.15 160/0 suggesting that the objective is intended for use without a cover glass. This is true, but more precisely this objective can work both without a cover glass and with one. In newer versions the engraving already reads 5/0.15 160/- where this "minus" already means "indifferent".

New (usually Chinese) microscope filters are sometimes not even made of glass. And even if they are made of glass - you may encounter scandalous examples where the glass is only surface-colored. Unfortunately, cheap colored glass filters may not be internally homogeneous and can cause light refraction distortions.

This filter set by PZO was originally sold together with the PZO Biolar microscope. It was manufactured in the 1970s (and certainly before 1977), so these are optical glasses that are about half a century old! They have never been used until now (this is so-called NOS - New Old Stock), therefore these are excellent old-class optical glasses of the highest quality.

Filters with a 32 mm diameter are used - and can be used - in microscopes from various manufacturers:
- Carl Zeiss Jena
- Zeiss West Germany
- Eschenbach
- Meopta
- Nikon
- ROW
- Leitz Wetzlar
- Wild
- Hund
- Kosmos
- and many others

Important - popular microscopes by Lomo (for example Lomo Biolam) have a 33 mm filter holder, so the filters shown here have too small a diameter and may fall out from some Lomo holders.

Description of this part for the microscope.

It transfers the light beam from the illuminator, properly focuses it using lenses and then reflects it vertically upwards using an angle mirror. This microscope element carries the manufacturer part number Leitz Wetzlar 020-452.010-025.

This part may solve the following problems that can occur in the Leitz Dialux 20 microscope:
- if artifacts in the form of lines are visible in the microscope image - this may indicate a crack in the light-collimating lens caused by high temperature emitted by the illuminator
- if the light-reflecting mirror is damaged: scratched, chipped, cracked or if the silver coating has oxidized

- lens mount marked: 0.8x 419610 (font characteristic for the Wild company. Number 419610 is the manufacturer catalog number)
- field widening lens: 0.8x MPS 195182 (number 195182 is the catalog number of this lens)
- Wild Leitz / Wild MPS 52 photo tube (Heerbrugg Switzerland) with connector for the MPS 46 control console (important - the console is not included)

The mounting diameter on the microscope side is 40 mm.

This tube is currently commonly used for connecting digital cameras or photographic cameras to microscopes with a trinocular head. There is a lot of information about this online as well as DIY step-by-step guides on internet forums. It allows taking microscope photographs and, after minor modifications, it can also be used for macrophotography https://www.mikroskopia.de/serv-mps52-en.html.

Please note that the MPS 52 was sold during a period of ownership and manufacturer name changes. Leitz Wetzlar changed its name to "Leica", and Leica later acquired Wild Heerbrugg. Because of this, the following names are used interchangeably for the entire MPS 52 system:
- Wild MPS 52
- Leitz MPS 52
- Leica MPS 52
This is also visible on the element shown in the photographs:
- the adapter for Polaroid film backs is marked as Wild Heerbrugg
- while the tube itself carries the "Wild Leitz" logo

Jena
Name: Grossfeld Binocular
Eyepiece mounting diameter: 30 mm
Microscope mount: 41 mm dovetail mount
Diopter adjustment: yes, for one eyepiece

The set also includes two eyepieces:
- Model: Carl Zeiss Jena GF-Pw 10x (25)
- Mounting diameter: 30 mm

This head is most commonly used in the following microscopes:
- Carl Zeiss Jena Jenamed
- Carl Zeiss Jena Jenaval
- Carl Zeiss Jena Jenalumar
- Carl Zeiss Jena Jenapol
- Carl Zeiss Jena Jenvert
- Carl Zeiss Jena Jenatech
- Carl Zeiss Jena Jenalab

Interestingly, widefield binocular heads with a 30 mm eyepiece mounting diameter are sometimes also installed in older Mikroval series microscopes (for example Ergaval and Amplival). If the microscope is additionally equipped with GF-Planachromat series widefield objectives (or GF-Planapochromat objectives used in Docuval microscopes) - this creates the best possible combination for Carl Zeiss Jena microscopes with a 160 mm tube length.

This microscope head model is identical to the Baader Mark V binocular viewer used in astronomical telescopes and is often purchased by astronomy enthusiasts and adapted for telescope mounting.

Description of this part for the microscope.

microscope element allows expansion of a transmitted light microscope with a module for reflected light (EPI) observation:
- brightfield
- darkfield
- polarized light
- fluorescence
because this is exactly a "universal" illuminator.

The set includes a reflector cube for reflected light brightfield work. This is the Leica 1 BF 561034 cube (alternative number format: Leica 561 034).

Basic technical parameters of the Leica 565015 universal EPI reflected light illuminator:
- 4 filter cubes (reflectors) can be installed, for example brightfield BF (already installed here), darkfield DF, fluorescence cubes
- 4 round filters with 32 mm diameter can be installed
- a light source must be installed
- a polarizer and analyzer can be installed
- mounting connection to microscope body: 44.5 mm dovetail
- head mounting connection: 44.5 mm dovetail

The Leica 565015 EPI illuminator is modular and can be configured according to individual requirements. The example shown and offered here is a basic version which must be completed according to the user's own needs (however the "Leica 1 BF" reflector is already installed).

NOTE - as visible in the photos and in the video, the cover flap (protective cover) which covers the rotating turret with filter cubes (reflectors) is missing.

Description of this part for the microscope.

This microscope element is responsible for precise (fine / micro) focusing of the microscopic specimen image.

Mechanically, this module is located between the holder to which the microscope stage is attached and the main focusing block with the focusing knobs. Thanks to this, it transfers the rotational movement of the fine focus control into the vertical movement of the microscope stage.

It is worth noting that in the Wild Heerbrugg M20 microscope this mechanism is based on two planes moving on linear guides with bearing balls, rather than on a gear system as used in most microscopes. However, the method of lifting the entire mechanism using a pin is similar to that found in microscopes such as the Lomo MBI-1 or Carl Zeiss Jena Lg.

contains:
- the coarse focus knob (macro movement), which transfers rotational movement to the rack gear (available separately)
- the fine focus knob, which transfers rotational movement to the bearing-based precision mechanism (available separately)

In the last photos in the gallery I indicate with an arrow exactly which microscope element this is and where it is located inside the microscope.
