These are names commonly used to refer to this manufacturer of microscopes and microscope parts, even if they are not official.

# Description and specifications:
Fine focus knob (micro movement) with 0-360 scale for the Carl Zeiss Axiolab microscope.

This knob was removed from a Zeiss Axiolab re microscope, P/N 45 09 05 (also written as 450905). However, it also fits the following variants:
- Zeiss Axiolab drb KT, which carries the same number 45 09 05 (450905)
- Zeiss Axiolab E re, 45 09 07 (450907)
- Zeiss Axiolab A (reflected light), 45 09 09 (450909)
- Zeiss Axiolab Pol, 45 09 10 (450910)

The knob carries a collar with a 0-360 scale, which is an angular measure describing one full turn of the knob.

The knob is mounted on the shaft (the shaft inside the stand body that connects the knobs on the right and the left side of the microscope) with a small grub screw, which is included.

I was not able to confirm this, but in my opinion it is very likely that this knob also fits the following microscopes:
- Zeiss Standard 20
- Zeiss Standard 25 ICS
- Zeiss Axiostar
- Zeiss Axioskop 20
- Zeiss Axiovert 25

The Carl Zeiss Axiolab microscope has two such knobs. Both are identical, so there is no difference between the right and the left knob. I am offering each of these knobs separately (one at a time).

The last photo shows the stand of the Zeiss Axiolab microscope, with an arrow pointing at the knobs in question.

# Examples of use
- as a service part, if you need to replace a damaged knob or if this knob is missing
- if you have confirmed compatibility and want to fit this knob to a different microscope model
- if you want to use this knob with its 0-360 scale for your own DIY project, for example something related to polarization
