ABSTRACT:
An optical beam switching mechanism is used from switching a light beam between a plurality of light beam paths. A rhombic prism is mounted for rotation on an axis and is rotated between positions by a geneva mechanism. A plurality of microswitches are positioned to reposition the prism after rotation to a predetermined position. The geneva mechanism is driven by an electric motor and has an index wheel attached to a cradle supporting the prism which index wheel is rotated by a drive arm connected to the electric motor.
