Description of this part for the microscope.

5 mm or others if you put a thickening ring on it.
The upper lens for strong magnifications can be unscrewed and then we get a condenser for objectives with low magnification and low numerical aperture.
I can't (or it is not possible) unscrew the lower part with the diaphragm separately.

Focal length: 37 mm

The optics (lenses) in this microscope objective are in very good condition.

There's no manufacturer's marking on the objective lens. Because lenses from different manufacturers looked very similar at the time, I'm not sure whether Hertel & Reuss manufactured the lenses themselves or ordered them from another company (e.g., Leitz). Therefore, these lenses can be safely used with microscopes from many other manufacturers.

it fits the CN series or the STE-6 stereo microscope (I'll post here once I find out).

Modell: HAPRO

Update: I just tested it with a Hertel & Reuss CN-hf / CN-fl microscope. The illuminator fits perfectly, but the CN-hf / CN-fl doesn't have a mirror underneath (Umlenkspiegel), so you'll need to install one yourself and it will work perfectly (see last photos).

It is very possible that the knobs and mechanism from the focusing block fit other Hertel & Reuss microscope models, such as the CN-fle or Primus, but I have not personally verified this.

polarization kit
Intended for: monocular biological microscopes
Type: for working with transmitted light

This allows you to view objects in polarized transmitted light, which produces very beautiful effects, for example, when observing descaling agent, vitamin C, or sand.

The kit includes:
- a polarizer that attaches to the light source
- an analyzer that attaches to the eyepiece

NOTE: Make sure the eyepiece diameter is suitable for mounting the analyzer.

Modell: STELA

The unit offered here was used with a Carl Zeiss Stereomicroscope II microscope (as seen in the last photo).

It originally used an incandescent bulb, but over the years, someone replaced it with an LED and connected a transformer. It has a bracket that allows for mounting to virtually any microscope.

condenser
- three phase contrast objectives
- condenser holder with gear rack

Three phase contrast objectives:
- Hertel & Reuss 10:1 N.A. 0.30 Ph.
- Hertel & Reuss 40:1 N.A. 0.65 Ph.
- Hertel & Reuss 100:1 Oel N.A. 1.30 Ph.
- Thread: RMS
- Tube length: 170 mm
- Focal length: 37 mm

This particular set was used in a Hertel & Reuss Studio II microscope. For this reason, the condenser holder is included in the set, but of course the condenser can be removed from the holder and used with other microscope models.

Eyepiece diameter: 23.2 mm

A trinocular head is a binocular microscope head with an additional third optical port for connecting a camera or photographic device.

This particular unit comes from a Hertel & Reuss Studio II microscope, but it also works with any other microscope model from this manufacturer that has an interchangeable head with a mounting diameter of 50 mm.
NOTE - as far as I remember, not all H&R microscopes have an easily interchangeable head; this applies, for example, to the Primus model.

NOTE - some microscope models from Steindorff Berlin also have a head mounting diameter of 50 mm and are fully compatible with H&R heads - an example of such a microscope with a Hertel & Reuss head can be seen on Facebook at the following address: https://www.facebook.com/groups/136833493390496/posts/1722336908173472/

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

Among Hertel & Reuss low-magnification objectives, those with 4:1 magnification are most commonly found on the market. This 5:1 magnification model, especially in the newer housing version offered here, is rare.

This objective can be used with practically any microscope that

simple microscope stages with clips for holding the specimen. Therefore, at magnifications above 400x, manually manipulating the slide with the specimen becomes very difficult. XY cross stages are used for this purpose, for example, to move the specimen very precisely at 500x, 600x od 1000x magnification with oil immersion.

This is not a cheap plastic cross stage - it is a well-made Hertel & Reuss design.

NOTE - if the mounting pin spacing matches, this cross stage can be mounted on stages from virtually any manufacturer.

Note - this is version "A" of the XY cross-stage mechanism - it differs from version "B" only in the shape of the screws, but in order to ensure that my photos always show the original item, each variant is listed separately in the database.

Note - Hertel & Reuss manufactured cross stages with fixed specimen clamps as well as a model with a spring-loaded clamp. Here I present and offer the version with fixed clamps.

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)

Only towards the end of its operations did Hertel & Reuss begin producing microscopes with objectives having a 45 mm parfocal length. These were the Hertel & Reuss Labopan and Superpan models. Previously, microscopes from this company used objectives with a 37 mm parfocal length.

This objective fits practically any microscope from any manufacturer, provided that it has an RMS thread and supports objectives with TL=160 mm. Several examples of such microscopes are listed in the "Compatibility" section, but this is not a complete list.
