Microscope digital camera adapter for the HP Photo Smart 945. Microscope adapter fits one of the following: a 23mm inside diameter eyetube, a 30mm inside diameter eyetube, or a 23mm inside diameter trinocular port. Adapter threads directly onto the camera and then replaces the existing eyepiece by dropping directly into the eyetube or trinocular port. The adapter has custom 10x lenses built into it.
