ABSTRACT:
A high intensity light table, for use with a stereomicroscope having movable rhomboid arms, has an illumination source and a reflector. The table also includes light diffusing members which are rotatably mounted thereto. The diffusing members have: (1) magnets affixed thereto which are responsive to movement of the rhomboid arms of the instrument; and (2) means therein for selectively passing a beam of high intensity illumination. An auxiliary reflector, which is rotatable about the source of illumination, may be employed to substantially increase the intensity of the beam of illumination.
