The old Nikon Coolpix 995 and related models have a lens almost exactly the same size as a standard microscope eyepiece. There was an adaptor that you could screw onto the lens to connect to a microscope, but I got some fairly decent pictures just holding the camera up to the eyepiece. I suspect one could obtain a Coolpix 995 fairly inexpensively on ebay.
