ABSTRACT:
A high efficiency optical mixer includes a source of focused radiant energy. The focused radiant energy is concentrated by a parabolic concentrator onto an exit port. A diffuse reflector, which can be planar or arcuate, is maintained in contact with the output port thereby minimizing optical losses and diffusely reflecting light from the concentrator. The reflected light can be transmitted, by fiber optics, to an optical system. A method is providing for concentrating focused radiant energy onto a selected area and diffusely reflecting same from that area.
