Abstract:

A multiple beam optical system includes a housing which contains a pair of laser diodes and a pair of optical detectors. The lasers produce overlapping beams of light. The housing includes a beam directing and reflecting member which selectively focuses light from one of the lasers to a corresponding optical detector located in the housing and selectively focuses light from the other laser to its corresponding optical detector located within the housing. The individual power of each of the overlapping laser beams is thereby monitored by the separate detectors.
