supply:
Manufacturer: Carl Zeiss
Model: NAG 6V 20W stab.
Catalogue number: 45 84 15 - 9901
Input: 100-120-230-240 V
Output: 6 V
Output power: two outputs. It can supply either 2 × 10 W or 1 × 20 W
Power connector: separate computer-type power cable
Potentiometer: yes, smooth adjustment

This power supply has a maximum output power of 20 W and provides two outputs, allowing two 10 W illuminators to be connected and operated simultaneously.

However, it is a universal power supply and can be used with any microscope illuminator using a light source (lamp) rated at up to 20 W and operating at 6 V. Since most Zeiss microscopes use 6 V 15 W lamps, this power supply is suitable for virtually every microscope equipped with such illumination.

This power supply is most commonly used with microscopes employing 6 V 10 W halogen lamps, where both the transmitted-light illuminator and the reflected-light EPI illuminator are connected to the same power supply. Examples include:
- Zeiss D / DR / DRC / SV (Stemi) stereo microscopes
- Zeiss KF-2 biological microscope
- Zeiss ID2 inverted microscope

Special illuminators designed to work with this power supply were even manufactured for the Zeiss D / DR / DRC stereo microscopes:
- transmitted-light base "Zusatz für Durchlicht" with a 10 W halogen lamp
- auxiliary illuminators "Leuchte 10" / "Leuchte 10 S" with a 10 W halogen lamp
- vertical illuminator "Epileuchte" with a 15 W incandescent lamp

"Leuchte 10S" illuminators on a flexible arm, together with this particular power supply, are frequently used as a source of side reflected illumination for the Zeiss KF-2 biological microscope.

Examples of other microscopes whose 6 V 15 W illumination is compatible with this power supply:
- Zeiss Standard 16 / WL / GFL
- Zeiss Universal / Photomicroscope
- PZO Biolar
- PZO MST-130 / 131
- Carl Zeiss Jena Ergaval / Amplival
- Carl Zeiss Jena SM-xx
- this power supply can also be used externally to power the halogen illuminator of Carl Zeiss Jena Jenamed microscopes if the internal power supply fails (Jenamed uses a 6 V 20 W halogen lamp)

Note - different manufacturers and different illuminators may use different pin spacing in their 6 V connectors. It may therefore be necessary to modify the connector in order to connect it to this Zeiss power supply.

supply:
Manufacturer: Carl Zeiss
Model: NAG 2...12V 100W
Catalogue number: 39 25 85
Input: 100-110-120-127-220-240 V
Output: 12 V
Output power: 100 W
Power connector: separate computer-type power cable
Potentiometer: yes, smooth brightness adjustment

Designed for any microscope illuminator using a light source (lamp) rated at up to 100 W and operating at 12 V. It is most commonly used with external HAL 100 halogen illuminators (so-called Lampenhaus units), for example in reflected-light EPI illuminators.

This power supply can be used with illuminators and microscopes from any manufacturer. Here are several configurations verified in practice:
- compatible with the PZO Biolar DIC microscope fitted with the PZO OH-1 halogen illuminator, replacing the PZO ZM-100 or PZO ZH-100 power supply
- if the internal power supply in the base of an Olympus BH-2 BHS microscope fails, the original halogen illuminator can be powered using this external Zeiss power supply
- compatible with the large external halogen illuminator used for reflected-light EPI illumination on Carl Zeiss Jena Amplival Pol and Vertival microscopes
- also compatible with the Reichert Zetopan microscope equipped with the LUX-US 12 V 100 W halogen illuminator

Note - different manufacturers and different illuminators may use different pin spacing in their 12 V connectors. It may therefore be necessary to modify the connector in order to connect it to this Zeiss power supply.

Reichert Neozet microscopes, these rails serve only a decorative purpose.

However, the Reichert Zetopan microscope was also available in a version equipped for fluorescence illumination. The large size of the illumination unit used (for example the Binolux 3 model), which was mounted at the rear of the microscope, made it necessary to raise the entire microscope. For this purpose, Reichert Austria offered a special raising base (referred to by the manufacturer as the "sub-base", catalogue number 9 18 87 01). This raising base was equipped with retaining clips that attached to the microscope base, and those clips engaged precisely with the chrome-plated side rails presented here.

The particular rails presented here were removed from a Reichert Zetopan microscope. To the best of my knowledge, they are also compatible with the Reichert Neozet model.

Although two identical rails are mounted on the microscope base, I offer each rail separately. Very often only one rail breaks, so the user needs to replace only a single one. Please note that the chrome plating on the rails presented here is incomplete in places due to the age of these components.

to manufacture such a protective cover for the base of a Reichert Zetopan microscope themselves, here are its dimensions:
Length: 223 mm
Width: 156 mm
Sheet thickness: 1.5 mm

The base of the Reichert Austria Zetopan microscope contains the optical light path, and from time to time this area requires maintenance, especially cleaning. Since Reichert Zetopan microscopes are now 50-60 years old, it is not uncommon to encounter examples where this cover has been lost over the years.

Without this protective cover, contaminants can enter the optical light path and reach the mirror prism of either the transmitted-light or reflected-light illumination system, which may result in reduced image quality.

inside the microscope base beneath the condenser. It is secured from above with three screws. The collector housing also incorporates a holder for 32 mm round filters.

This component performs several functions:
- it collimates the light beam
- it also serves as a holder for round filters
- it redirects the horizontal light beam coming from the lamp house vertically upwards
- the flip-out wide field lens provides even illumination of the entire specimen when using low-magnification objectives

Replacement of this collector in a Reichert Zetopan microscope may be necessary in the following situations, among others:
- if this component is missing because someone removed it, for example during an unfinished repair
- if the upper protective glass of the collector has been broken
- if the mechanism operating the flip-out wide field lens has been damaged
- if - as often happens - the mirror prism has been damaged, broken, or its reflective surface has deteriorated through oxidation

- it protects the inside of the revolving magnification changer against dust and dirt entering the mechanism

Important: this nameplate does NOT fit the following microscopes:

- Carl Zeiss Jena Citoval / Citoval-2, because these models use a continuously variable ZOOM magnification system

Several decades have passed since the Technival series microscopes were manufactured, and these nameplates often simply fall off by themselves. They are also removed during servicing or repair of this microscope model, which is another common reason why they become lost.

Users solve the problem in various ways:
- they cover the "empty window" with almost anything
- they print a copy of the magnification table from a photograph of the original, glue it onto a piece of cardboard, and use this DIY replacement
- or they produce a replacement using a 3D printer, sometimes even with recessed lettering

However, if someone wants to have the original part, the only option is to find an original nameplate like the one offered here.

light source to be connected. The lamp house is installed on the left side of the microscope, while the built-in mirror prism redirects the light beam into the EPI nosepiece.

Fluorescence light sources are most commonly connected to this mount, but it is completely universal. It contains no filters and can be used with LED, HBO, XBO, halogen or even classic incandescent lamp houses.

If the light source is lightweight (one of the newer models), it can be mounted without any additional supports. If a large, heavy lamp house is used, additional support frames are often employed to carry its weight (these are optional accessories and are not included).

In its current configuration, this mount accepts lamp houses with a 48 mm connection diameter. However, this mounting adapter can be removed, leaving a plain tube that can accept virtually any adapter, allowing almost any manufacturer's light source to be connected.

The last photograph in the gallery shows a Zeiss Photomicroscope III microscope with this lamp house mount installed. An arrow indicates its exact location, making it easy to identify this component.

The video gallery also contains two videos. The first presents this component from different angles and in close-up. The second demonstrates how to remove this EPI lamp house mount using a Zeiss Photomicroscope III microscope (commonly known as the Zeiss Phomi III) as an example.

knobs
- coarse focus mechanism with the rack and control knobs
- microscope base with the rear illuminator port and a decenterable field diaphragm (iris diaphragm)
- stand arm with the microscope head mount and a dovetail guide for the interchangeable objective nosepiece
- dovetail guide with a rack and drive knob, together with the mounting module for a pankratic condenser or a clamp for mounting another condenser.

When can a complete microscope stand be useful?
- if you are building a microscope yourself and selecting every component so that the final configuration is exactly what you need
- if you own an older model (e.g. Carl Zeiss Jena Lg) - replacing the stand acts as an upgrade, while the remaining components are compatible between these models (except for the condenser)
- if your microscope is damaged or in poor condition - in this case the stand simply replaces the damaged microscope component
- if you need to replace only a single component in your damaged microscope (for example the fine focus block or the iris diaphragm), but decide to replace the entire stand instead

Contact us if you are looking for any part to repair a Carl Zeiss Jena Lumipan microscope. Even if the required part is not currently visible in the photographs or has not yet been added to this database as a separate product, it is located inside this complete microscope and is available. Examples include:
- knobs and control knobs
- racks and gears
- guides and shafts
- housing parts
- the iris diaphragm or its individual components
- illumination system components, deflecting mirror
- many other parts, from the complete upper tube down to the smallest screw or spring

The parts listed above are only examples - other components from this microscope stand may also be available.

this module serves as the aperture diaphragm. The field diaphragm is built into the illumination path inside the microscope base.

At the same time, it provides a holder for 32 mm round filters. The video available in the gallery also demonstrates how a filter is inserted into this holder.

The sliding iris diaphragm mounted beneath the microscope condenser allows oblique illumination to be set, producing a three-dimensional image with enhanced contrast of transparent specimens (such as unstained cells). The resulting image is similar to differential interference contrast (DIC).

This component is known under various names, 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 diaphragm DOES NOT FIT the Carl Zeiss Jena Lumipan microscope, even though it appears very similar at first glance.

Because this module is removable, it is missing from a large proportion of microscopes available on the second-hand market. During decades of use, these diaphragm modules were frequently lost.

In addition, they are often damaged and need replacement. The most common failures include:
- the protective glass covering the diaphragm becomes scratched or broken
- the diaphragm blades become bent or broken
- the screw used to decenter the diaphragm bends or breaks
- the return spring responsible for restoring the diaphragm to its centred position becomes damaged or is missing

Replacing the damaged assembly with the diaphragm module offered here solves these problems.

several functions:
- it protects the electrical components built into the microscope base
- it protects the bulb located inside the microscope base
- it acts as a heat sink, dissipating the heat generated by the bulb

The last photograph in the gallery shows the complete Olympus CHK microscope. An arrow indicates exactly which component this is and where it is located, making it easy to identify correctly.

A large proportion of Olympus CHK microscopes available on the second-hand market are missing this cover. During many years of use, this sheet metal cover had to be removed whenever the bulb was replaced, and it was often never reinstalled afterwards.

Owners solve this problem in various ways, often using thick cardboard or a plastic cover. However, only a metal cover also performs the function of a heat sink.

Reichert-Jung microtomes were also marketed by American Optical (AO / AO-Spencer) - however, they are still the same instrument.

This page shows the central unit of the ultramicrotome. It is currently still complete and has not yet been dismantled for parts. In the future, this instrument will serve as a donor of spare parts for repairing other ultramicrotomes.

Please contact us if you are looking for any spare part for a Reichert-Jung Ultracut E / Leica Ultracut E ultramicrotome. Even if the required part is not currently visible in the photographs and has not yet been added to this database as a separate product, it is still inside this complete instrument and is available. Examples include:
- knobs and control knobs
- rack gears and gears
- guides, bearings and shafts
- housing parts
- electronic circuit boards and cables
- sensors and switches
- many other parts, from the complete upper tube assembly down to the smallest screw or spring

The listed components are only examples - other parts contained within this instrument may also be available.

In the video available in the video gallery you can see every control knob in motion, the movement of the upper tube assembly and specimen holder, as well as the overall condition of the instrument.

the microscope stage:
1. It fastens the stage to the stage holder - that is, indirectly to the microscope stand. This ring has a groove for the spring screw mounted centrally in that holder, as well as two cut-outs at the sides - for the centring screws. It is not, however, a dovetail - in Carl Zeiss Jena L-Stativ microscopes the stage is mounted on a wide ring.
2. Since it is a sliding ring, it is precisely this part that makes it possible to rotate the stage all the way around, even though this is not a polarizing stage.

This is a service part for the repair of a stage in which exactly this element has been damaged. It is not a complete microscope stage.

This ring contains a screw that makes it possible to lock the position, that is, to press the ring tight so that it does not rotate. This screw very often bends completely (for example during transport) or even breaks off. Breakage most commonly occurs when the sliding grease has dried out completely and someone tries to turn the stage by pushing on this screw.

Rotating stages of this kind were used in microscopes of the L-Stativ class, among others:
- Carl Zeiss Jena Lg
- Carl Zeiss Jena Lumipan
- Carl Zeiss Jena Lu
- Carl Zeiss Jena Lr

Remember that microscopes and microscope parts made by the Soviet company LOMO were often clones of Carl Zeiss Jena products. It is therefore possible that this element will also fit a Lomo microscope stage - but the dimensions of this part should definitely be compared very carefully first.

Carl Zeiss Jena produced such stages from the 1930s until roughly the end of the 1960s. During that period minor construction details were changed many times, so it is very important to correctly identify the model of the stage from which this element was removed.

- in the photo gallery a millimetre scale is visible next to every photograph
- the last photographs show a disassembled microscope stage, with an arrow indicating where this element is located in the stage
- the final photographs, in turn, show the complete Carl Zeiss Jena Lg microscope with this stage fitted

All of this makes it possible to confirm visually that this is exactly the element you are looking for.

Olympus CHK / CH / CH-2 microscope models were supplied with a square stage that does not include an integrated XY mechanical stage for precise specimen movement. Such a mechanism is a separate (optional) accessory mounted to the side of the stage, and this is exactly the accessory shown and offered here.

Basic information:
Item: XY mechanical stage attachment for microscope stage
Manufacturer: Olympus
Manufacturer's descriptive name: Fixed type mechanical stage with right downward coaxial knob for plane stage fixed
For microscope: Olympus CHK
Mounting method: attached to the side of the stage with two screws
Required stage thickness: from 10 mm to 12 mm

Important compatibility information:
Originally, this mechanical stage attachment was used on the Olympus CHK microscope. I have personally also installed it on Olympus CH and Olympus CH-2 microscopes, and it is fully compatible with both models.

If CH and CH-2 microscopes were originally supplied with an XY mechanical stage, they used the Olympus CH-MVR attachment, but this CHK version fits as well.

In addition, this XY mechanism is compatible with other microscopes provided that the stage thickness is between 10 mm and 12 mm. I have personally verified compatibility with the stages of the following microscopes:
- Carl Zeiss Jena Eduval
- Carl Zeiss Jena Laboval-2
- Motic SFC100

The last photographs in the gallery show the complete Olympus CHK microscope. An arrow indicates exactly which component is being offered and where it is located within the microscope. The final photograph also shows an Olympus CH-2 microscope fitted with this XY mechanical stage attachment.

In addition, the video available in the video gallery shows this stage from various angles and demonstrates the movement of all mechanical parts.

At magnifications above 400×, manually moving the microscope slide becomes very difficult. This is exactly why XY mechanical stage attachments are used, allowing the specimen to be moved with great precision at magnifications such as 600× or 1000× using oil immersion.

Mechanically, this lens assembly is located inside the microscope base beneath the condenser. It is secured from below (inside the microscope base) with two screws. The lamp is located inside the microscope base directly beneath this light collector.

This component performs several functions:
- it collimates the light beam
- thanks to the built-in frosted diffuser, it homogenizes the light so that there are no bright or coloured hot spots caused by the lamp filament
- it also serves as the holder for round filters

it is a similar microscope body that differs only in a few details.

This Zeiss Phomi II microscope body includes:
- the coarse and fine focus block together with the focusing knobs
- the base (also called the foot or base) with the rear illuminator port, field diaphragm (iris diaphragm), and built-in filters
- the microscope arm with the intermediate tube mount (dovetail clamp), photographic film compartment, and all knobs and switches

When can a complete microscope body be useful?
- if you are assembling a microscope yourself and selecting every component so that the final configuration is exactly the way you want it
- if you have an older model (for example, a Zeiss Universal without EPI reflected-light capability) - replacing the stand effectively upgrades the microscope, while the remaining components can be transferred because they are compatible between these models
- if your microscope is damaged or in poor condition - in that case, this microscope body simply replaces the damaged part

- Zeiss Universal
- Zeiss Ultraphot (although the original holder in this model is black)

This complete module consists of the following parts:
- the section with the condenser focusing knob for height adjustment, mounted onto a dovetail guide using a quick-release clamping mechanism
- the condenser holder with a toothed rack, condenser retaining screw and two centering screws
- a swing-out holder for a 32 mm round filter
- a swing-out wide field lens used to provide even illumination of the specimen when observing with low-magnification objectives

This holder accepts condensers with a dovetail mount - it is not intended for condensers with a diameter of 37 mm or 39.5 mm.

The image gallery contains detailed photographs of this part together with its dimensions.
In the last photograph, an arrow indicates where this part is located inside the microscope.

Additionally, the video gallery contains two videos: the first presents this part from different angles, in close-up views, and demonstrates the movement of its moving components, while the second video shows, among other things, how to remove this condenser holder from the microscope body using a Zeiss Photomicroscope II as an example.

The Zeiss Universal, Zeiss Ultraphot, the earliest versions of the Zeiss Standard WL, and the first model of the Zeiss Photomicroscope were originally factory-equipped with this component in black.

The Zeiss Photomicroscope II, Zeiss Photomicroscope III, and the later versions of the Zeiss Standard WL were factory-equipped with this component in grey.

The colour of this component has no effect on compatibility. In other words, a component of either colour fits all of the microscope models listed above.

Numerical aperture N.A.: variable, from N.A. 0.16 to N.A. 1.4
Aperture diaphragm: no
Compatible microscope: Carl Zeiss Jena Lumipan

Mechanically, this condenser is mounted on a dovetail guide located beneath the microscope stage.

Several important notes:
- this pancratic condenser is compatible only with the Carl Zeiss Jena Lumipan microscope
- this condenser is not compatible with the Carl Zeiss Jena Nf or Carl Zeiss Jena Nu / Nu2 microscopes, even though the condenser used in those models is very similar
- this condenser does not include an iris diaphragm because the Carl Zeiss Jena Lumipan microscope has its aperture diaphragm located in the microscope base, directly below the condenser

In the last photograph, an arrow indicates which component is being described and where it is located in the microscope, making it easy to identify this part. In addition, the attached video shows how the individual components of this condenser move.

This condenser is often used as a "donor of parts" for DIY projects, for example:
- the Apl. 1.4 lens is often used to modify (upgrade) condensers with a lower numerical aperture N.A. in various microscopes
- the dark-field lens is very often used to build a custom cardioid condenser

Photomicroscope (Phomi) microscopes.

This cover ring contains a small screw that secures the ring in place so that it fits tightly around the joint between the two microscope components.

The accompanying video, using a Zeiss Photomicroscope II as an example, shows exactly where this cover ring is located on the microscope and how it is installed and removed.

On the secondary market, many Zeiss Phomi (Photomicroscope) and Zeiss Universal microscopes are missing this cover ring, which may allow dust to enter the optical system. Why is this cover ring often missing?
- first, it can be removed very easily, so over the years it may simply get lost
- secondly, the microscope body and the trino intermediate tube are often sold separately, so this cover ring frequently ends up being included in neither the first transaction nor the second

Description of this part for the microscope.

This is a round plastic cap with a metal insert, designed to cover the output port of the EPI illuminator. It is removed when an EPI fluorescence illuminator turret is installed (for example, on the Zeiss Photomicroscope III RS).

Please note that some versions of the Zeiss Universal microscope do not have an EPI reflected-light illuminator port.

On the secondary market, many Zeiss Phomi (Photomicroscope) and Zeiss Universal microscopes are missing this cap. As a result, dust can enter the illumination system (in other words, the light path). Why is this cap often missing?
- first, it can be removed very easily, so over the years it may simply get lost
- secondly, the microscope body and the EPI fluorescence illuminator turret are often sold separately, so after the turret has been removed, the EPI illuminator port remains uncovered

ameters:
Manufacturer: Lomo
Model: PLAN 25x0.50 P
Original designation: ЛОМО ПЛАН 25х0,50 П
Magnification: 25x
Numerical aperture N.A.: 0.50
Tube length: 160 mm
Cover glass: yes, 0.17 mm thickness
Immersion oil: no - this is a dry objective
Focal length: 45 mm
Thread type: RMS
Additional designation: P (Cyrillic: П) indicates that this objective is designed for use with polarized light
Special features: built-in iris diaphragm
Year of manufacture: 1976

This objective has a standard RMS thread and TL=160 mm, which means it can be used with the vast majority of microscopes from virtually any manufacturer, including Olympus, Zeiss, Nikon, PZO, Carl Zeiss Jena, Reichert, Wild and many others.

The built-in iris diaphragm allows, among other things, precise centering of the objective, because in a polarizing microscope the following diaphragms may operate simultaneously:
- field diaphragm in the illuminator
- aperture diaphragm (or two aperture diaphragms) in the condenser
- iris diaphragm in the microscope objective
- iris diaphragm in the eyepiece head
and accurate centering of all of them relative to each other is very important in polarized-light observations.

Objectives marked "P" / "Pol" feature a special construction in which the lenses are mounted and cemented in a way that prevents mechanical stress. They can be used both for conventional brightfield microscopy and for observations in polarized light.

parameters:
Filter colour: blue, matt
Function: NCB - converts the yellow light of the halogen lamp into naturally white light
Mounting diameter: adjustable from 25.5 mm to 26 mm

Mechanically, this filter is mounted on the front end of the halogen illuminator (over the light output opening). Its effect is to produce light with a colour similar to that emitted by a cool white LED.

Description of this part for the microscope.

This is a dedicated eyepiece head for a polarizing microscope. It features:
- an adjustable draw tube with an engraved 150 mm - 190 mm scale
- a groove at the top of the eyepiece tube for locking the polarizing eyepiece in a fixed rotational position
- a locating pin (threaded pin) in the dovetail mount securing the head to the microscope body, allowing the head to be locked in a fixed position

Basic dimensions and specifications:
Compatible eyepiece diameter: 23.2 mm
Microscope body mounting type: dovetail
Dovetail diameter: 40.5 mm (compatible with, among others, Carl Zeiss Jena and Lomo microscopes)
TL scale range: 150 mm to 190 mm

The adjustable draw tube allows the use of microscope objectives corrected for different tube lengths (TL), for example:
- common polarizing objectives with TL = 160 mm (e.g. Carl Zeiss Jena and most other manufacturers)
- commonly encountered objectives with TL = 170 mm (e.g. older Leitz Wetzlar or Meopta)
- polarizing objectives with TL = 190 mm (e.g. Lomo)

Important: When calculating the total tube length (TL), the thickness of the mounting flange of the microscope eyepiece must also be taken into account.

Basic stand dimensions:
Support column diameter: 15 mm
Overall support column height: 220 mm
Glass plate opening diameter: 93.5 mm
Base length: 180 mm

The support column of this stand has a diameter of 15 mm. This allows virtually any stereo microscope or EPI metallurgical microscope with a 15 mm mounting bore to be installed on it, including:
- Carl Zeiss Jena Stemi SM-XX
- PZO MST-110 / MST-127
- PZO MST-130 / MST-131

When might this stand be needed?
- Stereo microscopes, including the Carl Zeiss Jena SM XX series, were often used on special holders or boom stands. As a result, many of these microscopes available on the second-hand market no longer include their original bench stand.

(Phomi) microscopes.

This is an intermediate tube forming the main optical module of the microscope. It is mounted onto the microscope arm, and the binocular head is then attached to this intermediate tube. The module integrates the following components:
- a third optical path (photo output), which is why this module is sometimes referred to as a trinocular tube
- an Optovar magnification changer with a Bertrand lens
- a dovetail mount for the objective revolver
- a large insert for a round filter and slots for additional inserts

This intermediate tube is compatible with the following microscopes:
- Zeiss Universal (Carl Zeiss Standard Universal)
- Zeiss Photomicroscope (Zeiss Phomi)

The Optovar magnification changer integrated into this intermediate tube features a rotating turret with the following positions:
- PH (Bertrand lens)
- 1.25×
- 1.6×
- 2×

The complexity of this design makes the module susceptible to damage of individual internal components, especially the optical elements (prisms and lenses).

illuminator housing.

This particular mounting screw was part of a fluorescence illuminator installed on a Nikon Optiphot microscope. Hg 100W / HBO 100W fluorescence illuminators, as well as similar versions with the same mechanical design, were used in, among others, the following microscopes:
- Nikon Optiphot
- Nikon Labophot
- Nikon Microphot
- and the EPI fluorescence illuminators used with these microscopes

This mounting screw is frequently exposed to damage because it protrudes beyond the outline of the illuminator housing. As a result, it is often bent or even broken, especially during transport.

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 the exact dimensions of this mounting screw. The last photograph also shows the complete fluorescence illuminator from which it was removed, making it possible to confirm compatibility with complete confidence.

This particular finned radiator was originally installed in a fluorescence illuminator fitted to a Nikon Optiphot microscope. Hg 100W / HBO 100W fluorescence illuminators, as well as similar versions with the same mechanical design using the same passive finned radiator, were used in, among others, the following microscopes:
- Nikon Optiphot
- Nikon Labophot
- Nikon Microphot

Therefore, this cooling component is also compatible with these microscopes. Above all, it is a replacement part for repairing the fluorescence illuminator rather than a specific microscope.

The relatively fragile fins of this radiator are susceptible to mechanical damage (please note the small chipped area clearly shown in the video). In a fluorescence illuminator using a 100 W high-pressure mercury burner, efficient passive cooling is extremely important.

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 the exact dimensions of this component. The last photograph also shows the complete fluorescence illuminator from which this finned radiator was removed, making it possible to confirm compatibility with complete confidence.

continuous zoom system.

The technical name of this microscope part is: front fixed group (input group) of the pancratic zoom system. These are the two lenses permanently mounted inside the stereo microscope body, located above the main objective (Hauptobjektiv) of the stereo microscope.

This service part can help solve the following problems encountered when using the Carl Zeiss Jena Citoval-2 stereo microscope:
- if a lens has been mechanically damaged (scratched, cracked, or chipped)
- if a lens has become delaminated or its surface has been damaged by fungus (mold)
- if someone previously repaired the Citoval-2 microscope incorrectly and these lenses are either missing or in poor condition

In the last photographs, an arrow indicates exactly which microscope part is being offered and where it is located inside the microscope, making this component easy to identify. The final photograph shows a schematic diagram of the Greenough stereo microscope design.

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.

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.

Description of this part for the 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.

supply:
Manufacturer: Carl Zeiss
Model: VWH 200/C 250 f-3b
Manufacturer P/N: 39 26 34 (also written as 392634)
Supported fluorescence lamps: HBO 200 W/4 L1, HBO 200 W/4 L2 and CSI 250W
Input voltage: 220 V - 240 V
Power rating: 900 VA

This power supply was supplied as standard with Zeiss Photomicroscope microscopes (commonly known as the Zeiss Phomi) whenever the microscope was equipped with an HBO high-pressure fluorescence illuminator (also referred to as a burner or lamp).

The same or very similar illuminators with identical electrical specifications were used in, among others:
- Zeiss Standard WL
- Zeiss Photomicroscope
- Zeiss Universal
- Zeiss Ultraphot
- such illuminators were also occasionally adapted for use with other microscope models, including those made by other manufacturers
Therefore, this power supply is suitable for all of the applications listed above.

Please note: the last photograph shows a dent in the housing. This does not affect the operation of the unit. Since the dent is located on the underside of the housing, it is not visible when the power supply is standing on a laboratory bench.

IMPORTANT: Always protect your eyesight when working with UV illumination. Never exceed the recommended service life of HBO high-pressure lamps. Always follow the operating instructions supplied with the fluorescence illuminator.

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

Description of this part for the microscope.

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.

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

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.

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

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:
- these eyecups fit PZO eyepieces only
- these eyecups fit only PZO eyepieces with a mounting diameter of 23.2 mm
- these eyecups DO NOT FIT older PZO eyepieces with a knurled outer edge - an example of such eyepieces can be seen in the last gallery photograph
- the last gallery photograph shows an example of these eyecups installed on microscope eyepieces

Important: no dimensions are provided here. These eyecups fit only 23.2 mm microscope eyepieces manufactured by PZO (PZO Poland / PZO Warszawa). They do not fit microscope eyepieces made by other manufacturers. If a microscope made by another manufacturer (e.g. Lomo Biolam) uses PZO eyepieces, these eyecups will fit. If a PZO microscope (e.g. PZO Biolar) uses eyepieces made by another manufacturer (e.g. Carl Zeiss Jena), these eyecups will not fit even though the microscope itself is made by PZO. These eyecups fit the eyepieces - not a specific microscope.

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.

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
