Description of this part for the microscope.

are available in several variants:
- round polarizing microscope stage
- mechanical microscope stage with a central plate, used for reflected light EPI
- simple microscope stage with specimen clips
- simple microscope stage with a screw-mounted XY cross-slide mechanism
- mechanical microscope stage with an integrated cross-slide mechanism
[[/BLOK]

The stage offered here is exactly of this last type.

Mounting method: screw-mounted.

This particular microscope stage was used in a Hertel & Reuss Studio II microscope.
However, it is sufficient to measure the spacing of the mounting screws that attach the stage to the stand and, if they match, to use it with other microscope models as well.

Hertel & Reuss also manufactured microscopes that were sold under other brand names, therefore it is likely that this stage will also fit some microscope models sold under the following names:
- Kosmos
- Humboldt
- Beck

transmitted light
- precise adjustment in two axes
- rotating stage center with scale (accuracy: 0.1 degree)
- built-in electronic measuring sensors enabling position display on a dedicated readout unit (not included)
- position locking screws (movement lock)

The Carl Zeiss Jena BK 70x50 microscope is one of the most versatile small toolmakers microscopes. Its fully modular design and a wide range of accessories allow it to be configured as a workshop microscope, measuring microscope, for Schlieren observation, metallurgical use, or even biological applications. This stage is one of many options for expanding the BK 70x50 microscope.

Specimen holder: no

In the place where stage clips normally hold the microscope slide with the specimen, there is a black matte insert covering the central opening in the stage, which makes it possible to work with reflected light. As visible in the photos and in the video - it can be pulled out, and then it becomes a "normal" stage for work with transmitted light (although of course it lacks the clips that hold the specimen slide).

This particular stage worked in a Hertel & Reuss Metall microscope. YES - "Metall" is the model name and not a statement that the microscope is made of metal. It is the same stage that is used in the Hertel & Reuss Studio II microscope and it can be used on both of these microscopes.
However, it is enough to measure the spacing of the screws that mount the stage to the microscope stand - and if they match - it can also be used with other microscope models.

Hertel & Reuss also produced microscopes that were sold under other brand names, so it is likely that this stage will also fit some microscope models sold under the names:
- Kosmos
- Humboldt
- Beck (CBS Beck Kassel)

micrometer scale: no
- dedicated for polarization: no
- material: brass
- mounting diameter: 71 mm

This stage fits the following microscopes:
- Carl Zeiss Jena L-Stativ
- Carl Zeiss Jena Lg
- Carl Zeiss Jena Lu
- Carl Zeiss Jena Lr
- Carl Zeiss Jena Lumipan

This Carl Zeiss Jena stage also fits microscopes:
- Lomo MBI-1
- Lomo MBR-3
- Lomo Biolam
- Lomo sold under the names Bresser and Zenith

If any of the above microscopes currently has a fixed stage (screwed), it is possible to retrofit a holder for interchangeable stages ( like this: https://www.microscopeparts.eu/part/99175) - this applies to both Carl Zeiss Jena and Lomo microscopes.

From the 1930s to approximately the mid-1960s many German manufacturers produced microscopes with the same stage mounting standard, so this stage will also fit them.

How does compatibility of stages between Carl Zeiss Jena and Lomo microscopes work?
- Carl Zeiss Jena stages for L-Stativ microscopes have a mounting diameter of 71 mm
- Lomo stages for MBR-3 / MBI-1 microscopes have a mounting diameter of 73 mm
- The spring-loaded front screw and long side centering screws in the mounting holder compensate for these differences
- Carl Zeiss Jena stages are more solid, heavier, made of brass
- Lomo stages are lighter, made of aluminium with plastic elements

Note that although this is a round and rotating stage, it is not a polarizing stage. It does not have a micrometer scale to read how many degrees (0-360) the rotation has occurred. Without this scale it can of course be used for amateur observations in polarized light, however for professional applications this is disqualifying.

Jenamed Cytology
- Jenamed Hematology
Carl Zeiss Jena Jenamed 2 and Jenamed Histology microscopes already use different stages.

This particular example shown and offered here was removed from a Carl Zeiss Jena Jenamed Cytology microscope.

The stage in Carl Zeiss Jena Jenamed microscopes is a flat, smooth surface permanently attached with screws to the microscope body, onto which cross table mechanisms or specimen holders are mounted - various versions depending on individual needs.

Mechanically, this stage consists of two elements:
- a smooth upper steel surface attached to the cast form underneath
- the lower cast form (with manufacturer number), which is attached to the microscope body
Both parts have an opening for the microscope condenser. The condenser is mounted from the underside of the stage (condenser available separately).

Metal cast or injection-moulded microscope parts made by Carl Zeiss Jena have their own numbers. This part carries the number 2712 (full marking: Si10 CZ 2712).

In the last photo I indicate with an arrow exactly which element it is and where it is located in the microscope.

attached to the microscope stand with screws. It serves as a mounting platform for mechanical stages, XY stage mechanisms, or specimen holders - various versions depending on the user's requirements.

Mechanically, this stage consists of two elements:
- a smooth upper steel plate attached to the cast component below
- a lower cast component (with the manufacturer's part number) attached to the microscope stand
Both parts have an opening for the microscope condenser. The condenser is mounted from below the stage (condenser available separately).

Metal cast or injection-moulded microscope parts manufactured by Carl Zeiss Jena carry their own part numbers. This part is marked with number 2712 (full marking: Si10 CZ 2712).

This microscope stage DOES NOT FIT the following Carl Zeiss Jena microscopes:
- Jenamed 2
- Jenamed Variant
- Jenamed Cytology
- Jenamed Hematology
- Jenamed Fluorescence

More precisely: the lower part (marked Si10 CZ 2712) is identical to the one used in other Jenamed microscope models (except Jenamed-2), whereas the smooth upper steel plate used in the Jenamed Histology differs from those used in other models by the size of the condenser cut-out (opening).

In the last photo, I indicate with an arrow exactly which component is being offered and where it is located within the microscope.

allows both standard front-back and left-right movement using the adjustment screw and control knob, as well as smooth manual sliding by hand (clearly visible in the attached video).

This stage is mounted to the Wild M20 microscope in the same way as a standard XY stage, using screws.

Note - this stage may have either an opaque metal insert plate or a transparent glass insert in the center (if transmitted illumination from below is required). The example presented here has NO insert installed.

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

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

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