Abstract
1286787 Beam-splitting prism system FERNSEH GmbH 19 April 1971 [17 April 1970] 23323/71 Heading G2J [Also in Division H4] A beam-splitting prism system for splitting an incident beam 11 into partial light beams in different spectral regions comprises a first prism 9, the input face of which is open to the air, a first dichroic filter 8 such that light 13 of a first spectral region is transmitted, light 12 of a second spectral region is reflected, and light of a third spectral region is partially reflected at 14 and partially transmitted at 15, depending on the plane of polarization of the light of this third region, and second prism 10, doubly refracting elements 18 and 19, and second dichroic filters 20 and 21, to transmit light of the first and second spectral regions, respectively, but reflect light of the third spectral region, the two passages through the doubly refracting material rotating the phase of polarization of the light of the third spectral region by 90 degrees. The light 23, 24 of the third spectral region therefore emanates from face 25. Trimming filters 25, 26, 27 may be provided.
