Description of this part for the microscope.

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

The last photograph in the gallery shows the complete Olympus CHK microscope. An arrow indicates exactly which component is being offered and where it is located inside the microscope, making identification straightforward.

Description of this part for the microscope.

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.

screw was removed from a Olympus CH microscope, but it will most likely fit most models of the CH series, for example:
- Olympus CHK
- Olympus CHB
- Olympus CK2
- Olympus CH
- Olympus CH-2

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.

1960s, several Japanese companies produced microscopes based on Olympus designs. These included, among others, the following companies:
- Hitos Tokyo
- SWIFT Japan
- Union Optical
- Magna Tokyo
- Tiyoda Tokyo
- Yoshida
- Correct Tokyo
- ASA Tokyo
- ERMA Optical Works Tokyo
- Shimadzu Kalnew (Tokyo)
These eyepieces are an excellent complement to these microscopes.

of the slide with the specimen on the microscope stage.

The simpler Will Wetzlar microscopes of the V100 and V200 series were sold with a square stage that had no integrated mechanical stage mechanism for precise movement of the specimen. Such a mechanism is a separate (and optional) part, screwed to the side of the stage - and it is exactly this accessory that is offered here.

Basic information:
Item: mechanical stage attachment for a microscope stage
Manufacturer: Will Wetzlar
Fits: microscopes of any make with a stage from 10 mm to 12 mm thick
Mounting: screwed to the side of the stage, on the left, with two screws

Once this mechanism is fitted, the coaxial knobs used to move the specimen are located on the handle on the left side of the stage.

Important note on compatibility:

Originally, attachments of this kind were used in the Will Wetzlar microscopes of the V100 and V200 series (that is, in the VM-V1xx, VB-V1xx, VM-V2xx and VB-V2xx models). I have personally fitted it to the following models as well:
- Will Wetzlar V255, V150
- Carl Zeiss Jena Eduval
- Carl Zeiss Jena Laboval-2
- Motic SFC100
- Olympus CH
- Olympus CH2

This XY mechanism also fits microscopes of other makes, provided the thickness of the stage is between 10 and 12 mm.

It is also worth remembering that microscopes made by Will Wetzlar were sold under the following names as well:
- Hund Wetzlar
- Dr. G. Schuchardt Göttingen
- Opt. Inst. G.K.E. Schröder
Microscopes carrying any of these names should therefore also be taken into account when considering the compatibility of this mechanical stage attachment.

The last photograph in the gallery shows a Will Wetzlar microscope of the V100 series, with an arrow indicating which part is meant and where it sits on the microscope. In addition, the video in the video gallery shows this attachment from various angles, together with the movement of its moving parts.

At magnifications above 400x, moving the slide with the specimen by hand becomes very difficult. This is precisely why mechanical stage attachments are used: to move the specimen very precisely at, for example, 600x or at 1000x with oil immersion.

100x
Colour correction: achromatic
Model: E. 100 1.25 oil 160/0.17
Numerical aperture N.A.: 1.25
Cover glass: yes, 0.17 mm thick
Thread: RMS
Tube length: 160 mm
Parfocal length: 45 mm (long barrel objective)
Immersion: yes, oil
Operating mode: objectives marked "E." are already CF objectives (CFN to be precise) and need no additional correction

This objective needs no additional correction from a tube lens or from the eyepieces. That makes it possible to fit it to microscopes of other makes, and in photomicrography it works in direct projection mode (it throws the image straight onto the camera sensor, with no relay optics needed).

This is the so-called black series of objectives, named after the black plastic barrel. They were used mainly in the Nikon Alphaphot YS2 microscope. That was the period when manufacturers were experimenting with a new look for microscope parts, and exactly the same black series appeared for instance in the Leitz / Leica HM-LUX 3 microscope or in the Will Wetzlar V300 / V355 / V365 microscopes.

This objective fits practically any microscope of any make, provided it has an RMS thread and supports objectives with TL = 160 mm and parfocal lengths of 33 / 37 and 45 mm. A few such microscopes are listed in the "compatibility" section, but that list is not complete.
