# Description and specifications:
Knob for moving the prism, for Zeiss 452143 trinocular heads and similar ones.

The Zeiss 452143 microscope head, used mainly in Zeiss Axioplan 2 microscopes, has three light splitting modes:
- 0 / 100
- 50 / 50
- 100 / 0

The prism sits on a carriage and slides on rails - and this knob shown here is what moves it.
In the last photo an arrow shows where this part is located in the head, so that it can be identified without any doubt.

This particular knob was removed from a Zeiss 452143 microscope head - but most probably it also fits other heads of the Zeiss AIM systems and of Zeiss Axioplan 2 microscopes, for example:
- Zeiss 452142
- Zeiss 452143
- Zeiss 452145
- Zeiss 452146

These photo-trino heads are used, directly or through suitable adapters, among others in the following microscopes:
- Zeiss Axioplan 2
- Zeiss Axioskop 2
- Zeiss Axiophot 2
- Zeiss AIM
- Zeiss Axiotech
- and probably others

# Examples of use

# Also compatible with the following microscopes:
- Zeiss Axioplan 2
- Zeiss Axiophot 2
- Zeiss Axioskop 2
- Zeiss AIM
