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.

Due to their very high quality, they are often used with microscopes from other manufacturers, especially when Carl Zeiss Jena Planachromat objectives are mounted.

8x eyepieces are best suited for microscopes equipped with a head with a magnification of 1.5x or 1.6x. In such cases, using 10x or higher eyepieces can result in excessive magnification and sometimes poor image quality. In such cases, 8x eyepieces provide the best image and optimal magnification.

Gleitfett grades differ in their parameters.

Gleitfett I E10 and Gleitfett II E75 were supplied with the Carl Zeiss Jena micromanipulator.
The Gleitfett III E410 offered here was supplied with the Carl Zeiss Jena Neophot-21 microscope.

This MAY suggest (although I have no proof in the form of manufacturer documentation) that the lower numbers (I and II) and the lower values of the "E" parameter (E10 and E75) were intended for finer mechanisms - and may therefore have a lower viscosity, for example. The III E410 grease, with its high "E" value, was supplied with a heavy microscope built around massive mechanics - so it may well be thicker.

This grease can of course be used on microscopes from other manufacturers as well - a few are listed in the "compatibility" section, but that is by no means a complete list.

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).

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/

- mechanical microscope stage with an integrated cross-slide mechanism
[[/BLOK]

The stage offered here is exactly of this last type.

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:

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.

immersion operation and with a phase contrast ring.

Manufacturer: Lomo
Model: APO-WI-F 70x1,23
Magnification: 70x
Numerical aperture: 1,23
Correction: Apochromat
Tube length: 160 mm
Focal length: 33 mm
Immersion: yes - water
Cover glass: yes - thickness from 0.10 to 0.20 mm
Markings: APO = Apochromat, WI = water immersion, F = phase contrast
Thread: RMS
Year of production: 1972

Note: to work in phase contrast technology you need a Lomo KF-4 condenser (you can see it in the database under number 00653).

This is a professional microscope objective with a very wide range of applications. The main features that make this objective exceptional:
- water immersion is preferred by many users over oil immersion
- very high numerical aperture, allowing the objective to produce a high resolution image
- cover glass thickness correction ring

Standard biological objectives are designed to achieve the best image quality when the specimen is located under a cover glass with a thickness of 0.17 mm (hence the marking on objectives such as 160/0.17). Unfortunately inexpensive cover glasses often do not undergo strict production control and a single package may contain cover glasses with thicknesses of 0.14 mm or 0.19 mm, which reduces observation sharpness.
Thanks to the built-in cover glass thickness correction ring (abbreviated CGTCR, CGCC or CGCR) the objective can be adjusted for every specimen so that it operates optimally. This works even when the actual thickness of the cover glass is unknown, because the effect is simply visible and the adjustment can be done "by eye".

Although this objective is a so-called "short" objective, meaning with a parfocal length of 33 mm, after adding a 12 mm adapter (you can see it in the database under number 99140) it can be used with newer microscopes designed for objectives with a parfocal length of 45 mm.

The Lomo company produced adapters specifically for these objectives (converters) from RMS thread to M27 thread, which makes them a very attractive option for installation in modern Zeiss Axio series microscopes.

Description of this part for the 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)
