An adapter connects a small solid-state television camera to a viewing port of a microscope. The adapter has a zoom lens system to focus the image from the microscope mounted in a zoom lens barrel. The lens barrel is moved by rotation of a shaft of a pulse motor through a worm gear. A mirror within the housing 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 control rod which is connected to a gear bracket by a ball. The gear bracket is moved one direction by a first motor connected to a worm gear. The bracket is moved in another direction by a second motor and gear which meshes with gear teeth on the bracket.
