The illumination device provides illunination to a plurality of test slides mounted to the surface of the rotating drum. A viewing device is mounted to the casing and provides left and right lenses simulating a far vision of the illuminated test slide. A pair of near vision lenses is rotatably mounted inside the viewing device and may be rotated to overlap the far vision lenses to simulate a near vision of the test slide.

A motor mounted within the casing drives the drum in accordance with commands input through a remote control unit.
