Description of this part for the microscope.

it is a solidly manufactured construction from Reichert Austria, highly sought after on the used microscope market.

Note - if the spacing of the mounting holes matches, this attachment can also be installed on stages from other manufacturers.

Note - Reichert Austria produced specimen holders with fixed clamps as well as models with a spring-loaded clamp. Here I show and offer the spring-loaded version.

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.

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.

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.

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.

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.

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.

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.

Description of this part for the microscope.

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

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.

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.

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.

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

The last photographs in the gallery show the base of a Reichert Zetopan microscope (in this case the older black version). An arrow indicates exactly which component it is and where it is located. The collector is shown both from the outside and in its installed position inside the microscope base. This makes it easy to identify the component correctly.

Description of this part for the microscope.

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.

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.

illuminator attached to the rear of the microscope base). This light source is shared by both transmitted light (DIA) and reflected light (EPI). Inside the microscope base there are two light-directing mirrors operated by control knobs located on the top of the base housing. These controls are marked "EPI" and "MIX". The "EPI" switch moves a mirror into the light path, directing 100% of the light into the reflected-light illumination path (vertically upward through a dedicated lens located inside the microscope base). This is exactly the assembly offered here — the EPI reflected-light angle mirror switch complete with its mirror and movement mechanism.

Information taken from the manufacturer's English-language catalogue "Zetopan Research Microscope. Price List, Effective December 1, 1976":
- This component belongs to the microscope stand. The stand has catalogue number: 9 90 00 01

This component — or individual parts of it — is frequently damaged. Replacing it with the assembly offered here can solve, among others, the following problems:
- if the "EPI" control knob operating the mirror has become bent or broken
- if the light-directing mirror has cracked, chipped, become scratched due to improper cleaning, or its reflective surface has oxidised
- if the movement mechanism, gear, spring or guide pin has been damaged

The last photographs in the gallery clearly indicate, using an arrow, exactly which component is being offered and where it is located inside the microscope. This makes identification straightforward.

The video gallery also contains two videos. One demonstrates how this reflected-light angle mirror operates and moves while installed in the Reichert Zetopan microscope base. The second shows the component after removal, including close-up views from different angles and all of its moving parts.

illuminator connected at the rear of the microscope base). This light source is shared by both the transmitted light (DIA) and the reflected light (EPI). Inside the base there are two light-reflecting mirrors, controlled by knobs located on top of the microscope base housing. These switches are labelled "EPI" and "MIX". The "MIX" switch introduces a semi-transparent plate filter into the optical path; it reflects 50% of the light onto the reflected-light path (vertically upward, through a special lens fitted in the base) and passes the remaining 50% onward for transmitted-light illumination. It is precisely this module - the MIX switch with its beam-splitting plate and the mechanism that moves this filter - that I present here.

- if the "MIX" knob on the base that controls the semi-transparent filter has become bent or has broken off
- if this plate-type light-beam splitter has cracked or chipped, has become scratched through improper cleaning, or its reflective surface has oxidised
- if the movement mechanism has been damaged: the gear, the spring or the pin

In the last photos of the gallery, an arrow indicates exactly which element is meant and where it is located in the microscope. This allows for unambiguous identification of this element.
