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.

commonly used in microscopes with a 30 mm eyepiece mounting diameter:
- Carl Zeiss Jena Jenamed
- Carl Zeiss Jena Jenaval
- Carl Zeiss Jena Jenalumar
- Carl Zeiss Jena Jenapol
- Carl Zeiss Jena Jenvert
- Carl Zeiss Jena Jenatech
- Carl Zeiss Jena Jenalab

Interestingly, binocular heads with a 30 mm eyepiece mounting diameter are sometimes also installed in older microscopes of the Mikroval series (e.g. Ergaval and Amplival) - in such cases this eyepiece will also fit them, because - in general - eyepieces fit the head mounted on the microscope, not the microscope itself.

A single Carl Zeiss Jena PW 6.3x (25) eyepiece can solve the following problems:
- a second 6.3x eyepiece is missing to complete a pair
- a low magnification eyepiece is needed for use in a trinocular photo tube

(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.

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.

Because this is important, I will write it again: this is a single eyepiece, not a pair of eyepieces.

This is a solution for people who:
- either have a pair of these eyepieces, but one of them needs to be replaced
- or have a microscope with a monocular head

For Will Wetzlar microscopes, eyepieces from practically any manufacturer can be used, provided that they are designed for a finite tube length system and have a mounting diameter of 23.2 mm. However, many users appreciate having original parts.

This eyepiece also works the other way around - it fits almost any microscope from any manufacturer that allows the use of eyepieces with a mounting diameter of 23.2 mm. Users of microscopes from many manufacturers are happy to choose German eyepieces because of their high quality. I have included some examples in the "compatibility" section, but this is definitely not a complete list.

Mounting diameter: 23.2 mm

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.

Kind: PR (ПР) - projection eyepiece for photomicrography
Type: K - compensating eyepiece
Mounting diameter: 23.2 mm

Projection eyepieces are special microscope eyepieces used to project the microscopic image onto the sensor of a camera. Many microscope photo tubes and trinocular heads have a seat for a projection eyepiece.

The "compatibility" section lists the microscope models this eyepiece can be used with, but only LOMO microscopes are listed there, as examples, and that list is of course not complete. This projection eyepiece can be used with any microscope of any manufacturer, as long as it has a tube or another seat for an eyepiece of 23.2 mm diameter.

Kind: projection eyepiece for photomicrography
Intended for: microscopes corrected for objectives with TL = 170 mm
Mounting diameter: 23.2 mm

Projection eyepieces are special microscope eyepieces used to project the microscopic image onto the sensor of a camera. Many microscope photo tubes and trinocular heads have a seat for a projection eyepiece.

Leitz projection eyepieces of this magnification carry several different markings. You will find "Proj.-Ok. H4x", "Proj.-Ok. P4X" and - as on the item offered here - simply "Proj. 4x". The letter H stands for the Huygens design. Leitz also made projection eyepieces of other magnifications, 2.5x among them, so the 4x version is not the only one in this family.

The eyepiece is intended for microscopes with a mechanical tube length of 170 mm. The older Leitz stands are corrected this way, Orthoplan, Ortholux, SM and SM-D among others. Later microscopes of this brand already work with a 160 mm tube. In Leitz optics of this generation part of the chromatic aberration correction is deliberately moved from the objective to the eyepiece, so matching an eyepiece to an objective is not merely a mechanical question here.

Despite its name, this eyepiece behaves differently from a typical projection eyepiece. It does not form a real image at a fixed distance, but projects the image to infinity - exactly like an ordinary viewing eyepiece. This makes it excellent for the afocal method, that is, photographing with a camera that keeps its own lens placed above the eyepiece. Leitz itself built its photographic adapters on precisely this method.

Leitz "Proj." eyepieces also found use outside microscopy. Eyepieces of this family were part of the microprojection attachments for the Leitz Prado and Pradovit projectors, which threw the image of a specimen onto a screen for a whole lecture room. If you are completing such an attachment, this is exactly the part.

Use in a microscope with a 160 mm tube length remains a matter of your own DIY modification. Mechanically the eyepiece fits any 23.2 mm seat, but the intermediate image is then formed in a different place, so focus and image scale will come out differently from what the manufacturer intended. There is, however, a route that gives a beautiful combination: into a microscope of another manufacturer you fit a Leitz Wetzlar objective computed for 170 mm, and this eyepiece above it. The optical path is then entirely Leitz - objective and eyepiece work as they were designed to, and only the stand remains foreign, a PZO or a Carl Zeiss Jena one for instance.

The "compatibility" section lists the microscope models this eyepiece can be used with, but that list is of course not complete. This projection eyepiece can be used with any microscope of any manufacturer, as long as it has a tube or another seat for an eyepiece of 23.2 mm diameter - subject to the difference between 160 and 170 mm tube length (I write about this above).

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.
