# Description and specifications:
Eyepiece mounting tube for the head of the PZO MST-130 stereo microscope.

This is a tube with an assembled diopter adjustment ring allowing correction of a vision defect in one eye and proper adjustment of image sharpness.

In PZO MST-130 and MST-131 stereo microscopes the tubes are universal - there is no difference between right and left.

Basic parameters:
- Type: tube with diopter correction ring
- Eyepiece diameter: 34 mm
- Side: universal; right and left
- Color: black
- Version: short tube

Notice: PZO MST microscopes occur in the following colors:
- glossy black
- glossy ivory
- matte rough white
- other variants in export versions
This tube is BLACK.

Notice: Binocular heads of PZO MST 130 / 131 stereo microscopes are available in versions with long eyepiece tubes as well as short ones. Here I present and offer the SHORT version.

# Examples of use
- very often this tube is dented and an eyepiece cannot be inserted
- very often the diopter adjustment ring becomes damaged and does not function
- if you want diopter adjustment on both eyepiece tubes and replace the simple tube with one equipped with an adjustment ring
- if you need a tube with precise worm adjustment for your own DIY purposes
