This particular specimen was used in a Zeiss KM microscope, but I have also seen this objective model in Zeiss KF-2 ICS and Zeiss Axiostar microscopes. It fits many microscope models from this manufacturer; some examples are listed in the "compatibility" section.

It can be used with any microscope from any manufacturer together with a suitable phase-contrast condenser (or a phase-ring slider). Of course, the microscope must be compatible, i.e. support RMS objectives, TL=160 mm and FL=45 mm.

# Examples of use
- If you have a microscope without objectives and need to restock it using original parts
- If you have a microscope that doesn't have an objective lens with this magnification and want to restock it
- If you have such an objective lens, but it's of very poor quality or damaged
- If you're cautious and want to have a spare objective lens
