COLLIMATING OPTICAL SYSTEM FOR SEMICONDUCTOR LASERS Russian patent published in 2006 - IPC G02B27/09 G02B27/30 

FIELD: optical engineering.

SUBSTANCE: collimating optical system has objective disposed in series along beam path, which objectives are mounted in opposition to semiconductor lasers, and first group of prisms. Ribs of refracting two-faced angles of lasers are oriented in parallel to planes of semiconductor junctions. First positive component is mounted one after another along beam path behind group of prisms. Second group of prisms is disposed close to back focal plane of first positive component. The group of prisms separates input light beam along line being perpendicular to planes of semiconductor junction to two bundles. Polarization prism is disposed on the way of mentioned light beams to bring them into coincidence to one common light beam. Second positive component of the system has front focal plane brought into coincidence with back focal plane of first positive component.

EFFECT: increased brightness of output bundle of beams.
