Description of this part for the microscope.

diameter: 23.2 mm

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.

eyepiece has a worm thread (focus), which allows you to
- sharpen the crosshair image
- or completely remove the crosshair from the image.

The 23.2 mm mounting diameter means this eyepiece can be used with almost any biological / stereo / polarizing microscope - as long as it has a head for eyepieces of this diameter.

6x (and 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, 6x/8x eyepieces provide the best image and optimal magnification.

(8)
Magnification: 20x
Field of view: 8
Mounting diameter: 23.2 mm
Designation: PK = plan compensating - recommended for use with plan achromatic objectives, but they also work perfectly with achromatic and apochromatic objectives

Due to their very high quality, these eyepieces are often used together with microscopes from other manufacturers, especially when Carl Zeiss Jena Planachromat objectives are installed.

Important: these eyepieces can be used both with finite tube microscopes (e.g. 160 mm) and infinity-corrected microscopes. This means that they can be used, for example, both on a Carl Zeiss Jena Amplival microscope and on a Carl Zeiss Jena NU-2 microscope.

Note - in my opinion, eyepieces with such a high magnification are recommended rather for "inspection" than for continuous work. I deliberately write "I recommend" because this is my personal opinion based on practical use and not on the manufacturer's documentation.
An eyepiece magnification of 20x should rather be treated as a zoom without revealing additional details (the resolution is not increased). This is important, for example, in heads with built-in magnification (e.g. Carl Zeiss Jena heads with built-in magnification of 1.5x or 1.6x) - when working with a 100x oil immersion objective, we theoretically obtain 100*1.5*20 = 3000x, while physics does not allow the human eye to magnify visible light beyond approximately 1250x - therefore this is a so-called "empty magnification".

diameter: 23.2 mm

This eyepiece allows the microscope image to be projected onto a surface such as a wall, ceiling or projection screen.

Originally, this eyepiece model was supplied with the Carl Zeiss Jena Pictoval projection microscope. It can also be installed on virtually any microscope from any manufacturer with a 23.2 mm eyepiece tube.

Important: Projecting a microscope image requires a very large amount of light, so a high-power illuminator is necessary.

of view number: 12
Mounting diameter: 23.2 mm
Designation: PK = plan compensating - recommended for work with planachromatic objectives, but they also work without any trouble with achromats or apochromats

Because of their very high quality they are often used on microscopes from other manufacturers as well, especially when Carl Zeiss Jena Planachromat objectives are mounted in them. The "compatibility" section lists a long series of microscopes these eyepieces fit - but that list is definitely not complete.

Important: these eyepieces work both on microscopes with a finite tube length (160 mm, for example) and on microscopes with infinity optics. That means you can use them on the Carl Zeiss Jena Amplival microscope just as well as on the Carl Zeiss Jena NU-2 microscope.

A note - eyepieces with such a strong magnification are in my opinion better suited to a quick look than to permanent work. I write "in my opinion" on purpose, because this comes from using them and not from the manufacturer's description.
A 16x eyepiece magnification should be treated as a zoom that brings out no additional detail (the resolution is not increased). This matters for example with heads that have their own extra magnification (such as Carl Zeiss Jena heads with a built-in 1.5x or 1.6x factor) - working with a 100x oil immersion objective you then theoretically get 100*1.5*16 = 2400x, while physics does not allow light from the visible range to be usefully magnified for the human eye beyond roughly 1250x - so this is what is called empty magnification.

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.
