ABSTRACT:
An apparatus for directing a light path sequentially between multiple positions. A rotary switch rotates a light beam from a prism relative to a plurality of optical elements arranged radially on a switch body. In one embodiment, a prism rotates in the switch body, causing the light beam to sweep through the optical elements. In another embodiment, the switch body rotates about a prism transmitting the light beam. In various embodiments, the optical elements include a photodetector, a filter and a photodetector pair, a reflector, and a filter and a reflector.
