Abstract
An apparatus for controlling the illumination of optical examination devices adapted to be connected to the distal end of a light conducting cable connected at its near end to a source of light, which apparatus permits control of illumination of the distal end of the cable. The apparatus includes a housing connected to the distal end of the cable and adapted to receive optical examination devices. A filter support mounts a plurality of filters within the housing for selective movement in and out of the path of light eminating from the distal end of the cable. The filter support is moved by operating a positioning control on the housing which is mechanically coupled to the filter support. In operation, the optical examination device is mounted to the housing which serves as a handle for it, and the illumination of the device is selected by operating the positioning control with the same hand that holds the housing.
