OPTICAL TURNING DEVICE FOR LASER PROCESSING EQUIPMENT Russian patent published in 1997 - IPC

FIELD: laser machining; transmission of radiation in flexible manufacturing systems. SUBSTANCE: optical turning device makes it possible to direct radiation in four relatively perpendicular directions. Device has rotating truncated pyramid 1 with replaceable mirrors. Each mirror has its special function providing transmission of radiation of different lasers along one transmissions system. Radiation modifying mirrors are included into set of replaceable mirrors which makes it possible to slightly focus radiation transmitted over small distances, keeping aperture within tolerable limits. Truncated pyramid 1 with replaceable mirrors rotates both around its own axis and around axis coinciding with axis of incident radiation which provides pointing of beam in four relatively perpendicular directions. EFFECT: enlarged operating capabilities. 3 cl, 4 dwg
