ABSTRACT:
An adapter connects a small solid-state television camera to a viewing port of a microscope. The adapter has a lens to focus the image from the microscope, the lens being mounted in a slidable lens holder. The lens holder is slid by rotation of a manual control knob which is connected to a pinion gear in mesh with a gear rack on the lens holder. A mirror within the housing of the adapter, in its normal position, reflects the image 45 degrees and is a flat disk-shaped mirror mounted for universal movement about its center. The angle of the mirror is controlled by a finger-operated control rod which is connected to the mirror by a linkage system having a larger ball, a smaller ball mounted in a bore of the larger ball, and two pairs of rotatable mounts.
