# Description and specifications:
Mounting screw for the HBO / Hg 100W fluorescence illuminator used with Nikon Optiphot microscopes and other microscope models using this type of fluorescence illuminator housing.

This particular mounting screw was part of a fluorescence illuminator installed on a Nikon Optiphot microscope. Hg 100W / HBO 100W fluorescence illuminators, as well as similar versions with the same mechanical design, were used in, among others, the following microscopes:
- Nikon Optiphot
- Nikon Labophot
- Nikon Microphot
- and the EPI fluorescence illuminators used with these microscopes

This mounting screw is frequently exposed to damage because it protrudes beyond the outline of the illuminator housing. As a result, it is often bent or even broken, especially during transport.

Important: Nikon EPI fluorescence illuminators from that period were manufactured with several different lamp house designs. They are most commonly referred to simply as:
- Nikon Hg 100W
- Nikon HBO 100W
- Nikon HBO 100W HG Lamp House
- often the model is Nikon LH-M100CB-1

For verification, the photo gallery includes the exact dimensions of this mounting screw. The last photograph also shows the complete fluorescence illuminator from which it was removed, making it possible to confirm compatibility with complete confidence.
