This is description of this part:

Matt frosted filter (ground glass diffuser) for the condenser of a Lomo Polam polarizing microscope.

This matt filter acts as a diffuser. It transforms the harsh light from the lamp into homogeneous illumination, makes the lamp filament invisible and ensures that the entire specimen is illuminated evenly.

The filter is mounted on a swing-out holder, which is a separate module installed below the condenser. This allows the entire frosted diffuser to be swung out of the optical path. In this position, for example, illumination according to the Koehler standard can be adjusted.

Users employ various names for the matt filter mounted below the condenser. These include:
- matt filter
- frosted filter
- ground glass diffuser
- diffuser
- diffuser filter
- frost filter
- opal diffuser
- diffusing screen
- condenser diffuser
- swing-out diffuser

In the last photograph, an arrow indicates which microscope element is being offered and where it is located in the microscope, allowing this part to be identified unambiguously.

The holder with the frosted diffuser fits every model of the Lomo Polam microscope series (the model designation written in Cyrillic is given in parentheses):
- Lomo Polam S-111 (the Cyrillic designation looks like C-111)
- Lomo Polam S-112 (C-112)
- Lomo Polam R-111 (P-111)
- Lomo Polam R-112 (P-112)
- Lomo Polam R-113 (P-113)
- Lomo Polam L-211
- Lomo Polam L-213
- Lomo Polam LMPR
- also Lomo Polam R-312 and Lomo Polam R-311 (the Cyrillic designation is P-312 and P-311), although in these models the matt filter below the condenser is usually not required because these microscopes are intended primarily for reflected light work

The final photograph, in which I indicate with an arrow the mounting position of the diffuser below the condenser, is a poster containing a comparison table of various Lomo Polam microscope models. It will help you easily identify which model of Lomo Polam polarizing microscope you own.
