Abstract
An optical switch has a reciprocating prism. In one position of the prism, light passes from an input fiber, through a collimating lens, directly to a focussing lens and then into an output fiber. In another prism position, the collimated light is incident on the prism, is deflected by the prism and enters a different focussing lens and output fiber. Coaxially aligned with the lenses are respective precision molded conical recesses which flare outwardly to receive the precision ground conical ends of fiber terminations.
