This is description of this part:
Light intensity adjustment knob for Carl Zeiss Jena CF-250 group microscopes.
Compatible with the following Carl Zeiss Jena microscopes:
- Jenamed (models Variant, Cytology, Hematology, Histology, Jenamed-2, Fluorescence)
- Jenapol
- Jenavert
- Jenaval
- Jenatech
- Jenalumar
Please note - this is only the adjustment knob, that is the knob used by the microscope user to make the illumination brighter or dimmer. It is not a potentiometer and therefore not a part of the electrical circuit.
This knob features the characteristic white cap used on Carl Zeiss Jena microscopes, which is often lost during decades of microscope use.
Mechanically, this knob is attached to the potentiometer. The fixing screw is covered by a white metal cap.
In the last photo I indicate with an arrow exactly which element it is and where it is located in a Carl Zeiss Jena Jenamed microscope. In Jenaval and Jenalumar microscopes it is located on the microscope base.
What is this part needed for?
- as a service element in the form of replacing the complete assembly if exactly this element or one of its component parts is damaged in the repaired microscope
