Abstract
1522555 Beam-splitter CROSFIELD ELECTRONICS Ltd 2 March 1977 [3 March 1976] 08517/76 Heading G2J A beam-splitter for producing a plurality of parallel light beams from a single beam comprises a block of stress-free gloss having a pair of elongate parallel sides, a coating 80 on a first parallel side, coating 80 being such as to provide a high internal reflection, and a sucession of areas 86-96 on the other parallel side, each area 86-96 being differently coated so that a beam entering the block at a given angle of incidence undergoes a series of internal reflections between said parallel sides, a part of the beam emerging through each of said areas 86-96 to produce the parallel light beams. The coating on said other side is preferably formed of alternate quarter-wave layers of magnesium fluoride and titanium dioxide, suitable reflectance values for areas 86-96 being 86%, 82À5%, 77À5%, 69%, 52% and 2%. An image reproducing system incorporating such a beam-splitter is disclosed.
