These are names commonly used to refer to this manufacturer of microscopes and microscope parts, even if they are not official. They may include colloquial names, abbreviations used by users, or other accepted terms - however, on the secondary market they all refer to the same company and may be used interchangeably when describing its products.

# Belongs to category:
End caps

# Description and specifications:
Dust protection end caps for the eyepiece tubes of PZO stereo microscopes and colposcopes.

These end caps are designed to protect empty eyepiece tubes whenever the eyepieces are removed for transport or storage inside the wooden carrying case. Installing the caps prevents dust from entering the microscope head and reaching the internal prisms.

The offer applies to 2 (two) pieces, i.e. one pair. Each individual end cap features the original PZO logo.

These end caps fit stereo microscopes from any manufacturer, provided they use eyepieces with a mounting diameter of 34 mm:
- PZO MST-1 / MST-2
- PZO MST-130 / MST-131 / MST-132
- PZO MST ZOOM
- PZO KLP-21 / KLP-22 colposcopes
- DIY devices (e.g. queen bee insemination equipment) built using PZO MST stereo microscopes
- Meopta DM23
- Carl Zeiss Jena Stemi SM-16 / SM-20 (the so-called SM-xx series)
- medical optical instruments (e.g. ophthalmic slit lamps) manufactured by Carl Zeiss Jena and based on the SM-xx stereo microscope platform

These end caps do not fit microscopes using eyepieces with diameters other than 34 mm:
- they do not fit PZO MST-110 / MST-127 stereo microscopes because these use 23.2 mm eyepieces
- they do not fit Lomo MBC-1 / MBC-2 stereo microscopes because these use 30 mm eyepieces
- they do not fit Lomo MBC-9 / MBC-10 stereo microscopes because these use 32 mm eyepieces
- they do not fit Carl Zeiss Jena Technival / Citoval stereo microscopes because these use 23.2 mm eyepieces
- they do not fit Carl Zeiss West Germany stereo microscopes because these use 30 mm eyepieces
- they do not fit Euromex E-series and Z-series stereo microscopes because these use 30.5 mm eyepieces
- they do not fit Hertel & REUSS STE-series stereo microscopes because these use 31 mm eyepieces

The FAQ section of this database explains that these are genuine original parts rather than 3D-printed reproductions. It is worth repeating here: these are original vintage PZO plastic end caps. They are not generic "no-name" caps and they are not DIY parts made on a 3D printer.

The last photographs in the gallery show an example of these end caps installed on the head of a PZO MST-130 stereo microscope.
