These are names commonly used to refer to this manufacturer of microscopes and microscope parts, even if they are not official. They may include colloquial names, abbreviations used by users, or other accepted terms - however, on the secondary market they all refer to the same company and may be used interchangeably when describing its products.

# Belongs to category:
Screws

# Description and specifications:
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.

# Examples of use
- 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
