Microscope digital camera adapter for the Olympus FE series cameras. Microscope adapter fits a 23mm inside diameter eyetube, a 30mm inside diameter eyetube, or a 23mm inside diameter trinocular port. Adapter mounts directly onto the base of the camera body (in the tripod mount) and then replaces the existing eyepiece by dropping into the eyetube or trinocular port. The adapter has a custom 10x lens built into it and a parfocal adjustment feature so the eyepieces and camera adapter can be in focus simultaneously.
