# Description and specifications:
Guide cover for the focusing unit of the Olympus CX31 / Olympus CX41 microscopes.

This is a profiled moulded part made of thin plastic, covering the mechanism of the vertical movement (raising / lowering) of the microscope stage, that is the mechanism responsible for setting the sharpness (focusing). It is located behind the microscope stage, on the inner side of the microscope arm. This cover is screwed to the housing with three screws (they are included in the set I offer here). These screws have their own Olympus part number: CUTB3X8SA, which is very interesting, because the cover itself has no commercial part number of its own.

In the service manual for the Olympus CX31 / CX41 microscopes the manufacturer uses the official name "guide cover" for this part. The number AD7856 is placed on the part itself. Based on my experience with other, similarly marked Olympus parts, I believe this is the permanent numbering of this component and that the number can be used for identification.

The part is so delicate that it could even be described as "very thick foil". As a result, it is highly susceptible to mechanical damage.
