These are names commonly used to refer to this manufacturer of microscopes and microscope parts, even if they are not official.

# Belongs to category:
Eyepieces

# Description and specifications:
Wide-field eyepieces (pair) 10x/25 with a 34 mm mounting diameter for PZO stereo microscopes and colposcopes.

The offer covers 2 (two) pieces, that is one pair.

These eyepieces fit stereo microscopes of any manufacturer, provided they use eyepieces with a 34 mm mounting diameter, for example:
- PZO MST-1 / MST-2
- PZO MST-130 / MST-131 / MST-132
- PZO MST ZOOM
- PZO KLP-21 / KLP-22 colposcopes
- DIY devices (for example instruments for the artificial insemination of queen bees) built around PZO MST stereo microscopes
- Meopta DM23
- Carl Zeiss Jena SM-XX (the so-called SM-20)
- medical microscopes by Carl Zeiss Jena (for example ophthalmic slit lamps) built around SM-XX stereo microscopes

These eyepieces do not fit microscopes whose eyepiece diameter is other than 34 mm:
- they do not fit the PZO MST-110 / MST-127 stereo microscopes, because those use eyepieces with a 23.2 mm diameter
- they do not fit the Lomo MBC-1 / MBC-2 stereo microscopes, because those use eyepieces with a 30 mm diameter
- they do not fit the Lomo MBC-9 / MBC-10 stereo microscopes, because those use eyepieces with a 32 mm diameter
- they do not fit the Carl Zeiss Jena Technival / Citoval stereo microscopes, because those use eyepieces with a 23.2 mm diameter
- they do not fit the Carl Zeiss West Germany stereo microscopes, because those use eyepieces with a 30 mm diameter
- they do not fit the Euromex E series and Z series stereo microscopes, because those use eyepieces with a 30.5 mm diameter
- they do not fit the Hertel & Reuss STE series stereo microscopes, because those use eyepieces with a 31 mm diameter

PZO 10x/25 eyepieces reach very high prices on the second-hand market. If you own a PZO MST-130 stereo microscope or a compatible one without eyepieces and you need any pair of eyepieces at all to get the microscope working - then the following PZO eyepieces with a 34 mm mounting diameter are commonly available on the market:
- PZO 6.3x
- PZO 12x (also in a version with a linear or grid reticle)
- PZO WF 20x
- PZO 25x

# Examples of use
- if you use a PZO microscope and need exactly these wide-field eyepieces 10x/25 with a 34 mm mounting diameter
- if you use a PZO KLP-21 / KLP-22 colposcope and need a larger field of view by switching to wide-field eyepieces
