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.

CERTAIN, however according to my best knowledge the description should not be incorrect.

This is an element of the microscope head.
- based on the color I believe that this is a part manufactured by Nikon (from experience)
- based on the spacing of the screw holes I believe that this is the element to which a binocular tube (so-called "binocular") is attached
- it is NOT the actual bottom part of the microscope head housing, as in Nikon microscopes this is usually made of a metal casting (from experience)

If you are looking for this element because you need it to replace the one you have and which is, for example, damaged - then based on detailed photographs with a centimeter scale you will certainly recognize whether this is the part you need.

Basic parameters and technical data:
Element: microscope objective nosepiece
Manufacturer: Nikon
Manufacturer catalog part number: MBP71316
Manufacturer catalog designation: C-N6
Number of objective positions: 6
Thread: M25
Mounting method: dovetail

The nosepiece is mounted using a dovetail connection. This allows users who have more than one nosepiece to quickly exchange complete sets of objectives without removing them individually.
This makes it possible, for example, to keep a full set of low-magnification objectives on one nosepiece and a full set of high-magnification objectives on another, and quickly switch between them depending on current needs.

compatible with microscopes designed for a 45 mm parfocal standard It is mounted between the objective and the nosepiece/revolver so that optical focus is maintained despite the additional mechanical extension.

Leitz PLEZY differs from extension adapters available on the market in that it features internal anti-reflective optics, ensuring that despite the mechanical extension of the focal length the image quality is not degraded.

mechanical design.

This is the spherical rear reflector mounted inside the fluorescence illuminator behind the lamp. Its function is to collect and reflect the light that is emitted backwards and would otherwise be lost, directing it towards the collimating lens.

This particular reflector was removed from a fluorescence illuminator used on a Nikon Optiphot microscope. Hg 100W / HBO 100W illuminators of this type, or mechanically identical versions using the same rear reflector, were fitted to, among others:
- Nikon Optiphot
- Nikon Labophot
- Nikon Microphot

Therefore, the reflector presented here is also compatible with these microscopes. However, it should primarily be regarded as a replacement part for the fluorescence illuminator rather than for a specific microscope model.

When may the rear reflector need to be replaced?
- High-pressure fluorescence lamps used as the light source in these illuminators may explode, damaging the rear reflector and often the collimating lens as well.
- In addition, because the reflector is located immediately next to the light source, it is exposed to very high temperatures and is therefore susceptible to thermal damage.
- Another common issue is oxidation of the reflective surface over the course of decades. When this happens, the reflector loses its optical performance and the entire illuminator produces significantly less light.

Important: Nikon EPI fluorescence illuminators of that period were manufactured in several different lamp house versions. They are most commonly referred to simply as:
- Nikon Hg 100W
- Nikon HBO 100W
- Nikon HBO 100W HG Lamp House
- often the model is Nikon LH-M100CB-1

For confirmation of compatibility, the photo gallery includes precise dimensions of this component. The last photograph also shows the complete illuminator from which this reflector was removed, allowing compatibility to be verified with confidence.

lamp house.

This is the illumination collector lens combined with a heat absorbing filter that absorbs the heat generated by the light source (mercury arc lamp).

This particular collector lens and heat absorbing filter assembly was installed in a fluorescence illuminator used on a Nikon Optiphot microscope. Hg 100W / HBO 100W illuminators, or similar models with the same mechanical design and identical optics, were used in, among others, the following microscopes:
- Nikon Optiphot
- Nikon Labophot
- Nikon Microphot

Therefore, the optical module offered here is also compatible with these microscopes. First and foremost, it is a replacement part for repairing the illuminator rather than a specific microscope.

When may it become necessary to replace the heat absorbing filter or the collector lens that collimates the light beam?
- the high-pressure mercury arc lamps used as the light source in these illuminators may explode, damaging the rear reflector and often also the collimator lens.
- in addition, the collector lens located immediately next to the light source is particularly susceptible to damage due to prolonged exposure to high temperatures.
- another very common failure is that the filter simply cracks because of mechanical damage (although it is mounted without mechanical stress - it is intentionally fitted with slight clearance).

Important: Nikon EPI fluorescence illuminators from that period were manufactured with several different lamp house designs. They are most commonly referred to simply as:
- Nikon Hg 100W
- Nikon HBO 100W
- Nikon HBO 100W HG Lamp House

For verification, the photo gallery includes precise dimensions of this microscope part. The last photograph also shows the complete illuminator from which this microscope part was removed, allowing compatibility to be confirmed with certainty.

illuminator housing.

This is the finned radiator mounted on the top of the fluorescence illuminator housing.

This particular finned radiator was originally installed in a fluorescence illuminator fitted to a Nikon Optiphot microscope. Hg 100W / HBO 100W fluorescence illuminators, as well as similar versions with the same mechanical design using the same passive finned radiator, were used in, among others, the following microscopes:
- Nikon Optiphot
- Nikon Labophot
- Nikon Microphot

Therefore, this cooling component is also compatible with these microscopes. Above all, it is a replacement part for repairing the fluorescence illuminator rather than a specific microscope.

The relatively fragile fins of this radiator are susceptible to mechanical damage (please note the small chipped area clearly shown in the video). In a fluorescence illuminator using a 100 W high-pressure mercury burner, efficient passive cooling is extremely important.

Important: Nikon EPI fluorescence illuminators from that period were manufactured with several different lamp house designs. They are most commonly referred to simply as:
- Nikon Hg 100W
- Nikon HBO 100W
- Nikon HBO 100W HG Lamp House
- often the model is Nikon LH-M100CB-1

For verification, the photo gallery includes the exact dimensions of this component. The last photograph also shows the complete fluorescence illuminator from which this finned radiator was removed, making it possible to confirm compatibility with complete confidence.

illuminator housing.

This particular mounting screw was part of a fluorescence illuminator installed on a Nikon Optiphot microscope. Hg 100W / HBO 100W fluorescence illuminators, as well as similar versions with the same mechanical design, were used in, among others, the following microscopes:
- Nikon Optiphot
- Nikon Labophot
- Nikon Microphot
- and the EPI fluorescence illuminators used with these microscopes

This mounting screw is frequently exposed to damage because it protrudes beyond the outline of the illuminator housing. As a result, it is often bent or even broken, especially during transport.

Replacing the microscope head mounting screw in Nikon Eclipse microscopes may be necessary, among other reasons, when:
- this screw is missing from the microscope, which is common in used microscopes
- the screw in the microscope is bent or broken, which is common when the microscope has not been properly secured for transport
- the screw in the microscope is in poor condition, e.g. damaged because someone tried to force it loose with pliers

objective:
Manufacturer: LOMO, Russia (ЛОМО)
Magnification: 40x
Numerical aperture N.A.: 0.65
Serial number: starts with "92"
Year of manufacture: 1992
Tube length: 160 mm
Parfocal length: 33 mm - so-called short barrel objective
Cover glass: yes, 0.17 mm thick
Immersion: no - this is a dry objective
Specimen protection: yes, the objective has a spring-loaded front mount that prevents breaking the slide with the specimen
Thread: RMS

Why do I state the year of manufacture in the description of this objective? Older LOMO microscope parts (objectives, microscopes, heads) have the year of manufacture encoded in the serial number: the first two digits of the serial number are the year of manufacture. Many users want to complete their microscope with parts made in the same year as the microscope itself.

This is a so-called short barrel objective with a parfocal length of 33 mm.

This is a so-called short barrel objective with a parfocal length of 33 mm. It is very often mounted on a 12 mm extension, which allows it to be used in microscopes that require objectives with a 45 mm parfocal length. Professional adapters with protective optics, metal adapters and popular DIY 3D-printed adapters all work well here.

Fun fact: LOMO made adapters between the RMS and M27 threads. Thanks to them, this objective was fitted to the Lomo Biolam I and Lomo Biolam M microscopes. Owners of Carl Zeiss Axio series microscopes with M27 thread also took advantage of this and used these adapters.

LOMO objectives are very popular with owners of microscopes from other manufacturers. Due to historical ties, owners of Carl Zeiss Jena microscopes regard them as an obvious replacement for the German objectives.

This objective fits practically any microscope from any manufacturer, as long as it has an RMS thread and accepts objectives with TL = 160 mm and 33 mm parfocal length (or 37 / 45 mm with a suitable adapter). Several example microscopes are listed in the "compatibility" section, but the list is not complete.

Description of this part for the microscope.

20) is frequently used for macro photography with a microscope or a camera (via an RMS adapter or a bellows). Although it is an achromat, it renders fine detail very sharply and performs well in focus stacking. It complements a set together with the LOMO 3.7x, Carl Zeiss Jena Semiplan 6.3x and Nikon M Plan 10x.

Basic parameters of this objective:
Manufacturer: Lomo, Russia (ЛОМО)
Magnification: 8x
Correction: achromatic
Marking on the objective: 8 0.20
Numerical aperture N.A.: 0.20
Serial number: starts with "92"
Year of manufacture: 1992
Tube length: 160 mm
Parfocal length: 33 mm - so-called short barrel objective
Cover glass: not critical - objectives with such low magnification work both with and without a cover glass
Immersion: no (dry objective)
Thread: RMS

Important - this objective is suitable for direct projection photography, as it does not require plan-compensating optics.

A microscope objective with such low magnification (with a 160 mm tube length it gives an 8:1 reproduction ratio) is used, among other things, for observing or photographing:
- insects
- minerals
- inclusions in amber
- handwriting
- micro shells (micromollusks)
- and much more
