NOS Complete Fedorov Optical table for miscroscope USSR

Description

The microscope was not used. Complete components
Fedorov table for miscroscope.
This is special device for a polarisation microscope allowing to position a crystal in space. It allows to determine isotropy, uniaxiality or diaxiality, optical sign, direction of optical axes and other optical properties of a crystal.

Excellent condition. Seems to be a complete outfit, though I'm not sure since I'm not a microscopist.
Included items:
LOMO Universal Stage;
Top segments: nD-1,548; nD-1,647;
Bottom segments: nD-1,516; nD-1,548;
Objectives: 3.7x0.11; 5.5x0.16.
A rotating device located on the subject table of the polarization microscope (or as a single subject table), which allows to change the position of the crystal in the form of a thin slip for measuring optical constants.
Using a Födor table, isotropy, uniaxial or biaxial, optical sign, direction of optical axes, value of birefringence and a number of other crystal-optic characteristics are determined.
