This is description of this part:
Mounting screws for the illuminator on Carl Zeiss Jena Jenaval microscopes and similar models.
I offer 4 identical screws here. Also available singly.
These screws fit the following Carl Zeiss Jena microscopes:
- Carl Zeiss Jena Jenaval
- Carl Zeiss Jena Jenalumar
- Carl Zeiss Jena Jenapol
- Carl Zeiss Jena Jenavert
The so-called "small illuminators", that is the halogen 25W one (like this: https://www.microscopeparts.eu/gallery/99693) or the HBO 50W, are held by two such screws. Large HBO 250W illuminators with an integrated power supply are mounted on 4 such screws.
If your microscope has only one small illuminator (for example a Jenaval with transmitted light or a Jenavert with EPI illumination), you can extend it with a second (also small) illuminator. You will then need two screws for that.
What is unusual (and sometimes the reason why a user cannot find these screws for a long time) is that they are unscrewed FROM THE FRONT of the microscope. The heads of these screws sit in openings cut into the white sheet-metal side covers of the microscope. You can see these covers with the screw openings here: https://www.microscopeparts.eu/gallery/99692.
What is this part needed for?
- if such a screw is missing, has bent, broken off or been lost
- if you are extending your microscope with a second illuminator and have no mounting screws for it
