Confirm whether the microscope C-mount path is suitable for this adapter and whether the projected image circle matches the camera-adapter system.

2. Eyepiece Tube Installation

Eyepiece-tube installation depends mainly on the tube inner diameter.
Common microscope eyepiece tubes include 23.2 mm and 30.0 mm sizes.
