Microscope digital camera adapter for the Nikon L series cameras with 3-4x zoom lens. Applicable for the L10 and L20 series of Nikon cameras. Does NOT work with the L100 and L120 series of 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.
