Carl Zeiss Jena PK 20x (8) microscope eyepieces with a mounting diameter of 23.2 mm (pair)	Description of this part for the microscope. Plan compensating microscope eyepieces manufactured by Carl Zeiss Jena with a high magnification of 20x. Manufacturer: Carl Zeiss Jena Model: PK 20x ... (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 1001.520 = 3000x, while physics does not allow the human eye to magnify visible light beyond approximately 1250x - therefore this is a so-called "empty magnification".

Carl Zeiss Jena PK 16x (12) microscope eyepieces with a mounting diameter of 23.2mm (pair)	Description of this part for the microscope. Carl Zeiss Jena plan compensating microscope eyepieces with 16x magnification Manufacturer: Carl Zeiss Jena Model: PK 16x (12) Magnification: 16x Field ... 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 1001.516 = 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.

Carl Zeiss Jena PK 12,5x (16) microscope eyepieces with a mounting diameter of 23.2mm (pair)	Description of this part for the microscope. Carl Zeiss Jena plan compensating microscope eyepieces with 12,5x magnification Manufacturer: Carl Zeiss Jena Model: PK 12,5x (16) Magnification: 12, ... 5x Field of view number: 16 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.
