# Description and specifications:
Condenser focusing knob for the Olympus CX31 / Olympus CX41 microscopes.

This is a complete module consisting of the following parts:
- knob (plastic casting marked AB4317)
- steel shaft
- plastic pinion (sometimes simply called a gear) fitted onto this shaft

It is this rotary movement of the knob that is transferred to the toothed rack (https://www.microscopeparts.eu/part/92011), which in turn produces the vertical up and down movement of the condenser (the focusing of the microscope condenser).

Because both the knob and the pinion are made of plastic in this microscope model, it is a part that gets damaged very often.

# Examples of use
- as a service part, when a damaged condenser height adjustment knob (or pinion) needs to be replaced

# Removed from microscope:

# Also compatible with the following microscopes:
