Description of this part for the microscope.

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.

This service part may solve the following issues with Nikon C-TT trinocular heads :
- how to remove fungus from a prism?
- can delamination in a Nikon head prism be removed?
- can a mirror inside the prism be repaired if it has oxidized?
- cracked prism in a microscope head

The prism mounted on a carriage moves along guide rails - and this is exactly the element used to move it.
In the last photo, an arrow shows where this element is located inside the head, allowing precise identification.

Nikon C-TT photo trinocular heads are most commonly used in the following microscopes:
- Nikon Eclipse E600
- Nikon Eclipse E800
- Nikon Eclipse E400
- and likely others

Description of this part for the microscope.

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

The last photos in the gallery show the body of a Nikon Eclipse E600 microscope, with an arrow indicating which element is being referred to and where it is located. This helps prevent mistakes when identifying the element.

diaphragm) in the microscope base. It can be swung out, thereby removing the polarizing filter from the optical path. This means that it does not need to be removed when working in brightfield without polarization.

The catalog number of this component is: MBB75370.

Mechanically, this polarizer can be mounted on, among others, the following Nikon Eclipse series microscopes:
- Nikon Eclipse E400
- Nikon Eclipse E600
- Nikon Eclipse E800
- Nikon Eclipse 50i / 55i
- Nikon Eclipse 80i / 90i
- Nikon Eclipse Lv
- Nikon Eclipse Ci
- Nikon Eclipse Ni

Note - in commonly used terminology there is some inconsistency and foreign as well as incorrect names are often used:
- polaryzator
- polarisator
- polarizer
- polariser
- filtr polaryzacyjny
- filtr POL
- circular polariser
- CPL Filter
- POL filter
- polarisations Filter
- polarization Filter
- anaizator
- analisaor
- Analysator
- POL analizer
- polarization analyser

IMPORTANT: For polarized-light work, a rotating analyzer, an insert with a rotating analyzer, or an intermediate tube with a rotating analyzer is required to be used together with this Nikon C-SP polarizer.

Please note: this is a "CF" projection photo eyepiece, meaning "Chrome Free" (chromatic aberration free). The eyepiece itself carries no chromatic correction - for correct results it has to sit in the microscope objective. In the case of Nikon, those are the CF (CFN) and CFI objectives.

The standard 23.2 mm mounting diameter allows it to be used in the projection tubes of many microscopes from various manufacturers - both biological and stereo ones.

It has to be said that this is a very universal projection eyepiece. In the "compatibility" section I list only a small part of the microscopes this photo eyepiece can be used with.

From the experience of people I know, only testing a projection eyepiece yourself on a specific microscope setup gives you certainty about how it will behave.

With every configuration - different objectives, a different tube length, a different photo adapter, camera, DSLR, sensor size - the user will get a different result.

This applies to tests both on microscopes with finite tube length optics (for example the Nikon Labophot with 160 mm optics) and infinity optics (for example the Nikon Eclipse E600 infinity), and both on older stereo microscopes (for example the Nikon SMZ-10) and somewhat newer ones such as the Nikon SMZ-1500.

Please note: PLI is a series of projection eyepieces assigned to the CFI60 system (optics corrected for infinity / "I" as in "infinity"). I have, however, personally seen eyepieces from this series used on microscopes with optics corrected for a finite tube length (160 mm, to be precise).

This eyepiece contains no chromatic correction lenses, so that correction has to be built into the objective (in the case of Nikon objectives these are the CF / CFN / CFI series).

The standard 23.2 mm mounting diameter allows it to be used in the projection tubes of many microscopes from various manufacturers - both biological and stereo ones. It therefore has to be regarded as a very universal projection eyepiece. In the "compatibility" section I list only a small part of the microscopes this photo eyepiece can be used with.
