Abstract
994,638. Interference filters. C. ZEISSSTIFTUNG, [trading as JENAER GLASWERK SCHOTT & GEN.]. Aug. 1,1961 [Aug.17, 1960], No. 27929/61. Heading G2J. In an interference filter of alternate high and low index layers, some of the low index layers are of lead fluoride or of a mixture thereof with germanium, tillurium, silicon, or thallium fluoride, gold, copper or alkali metal in amounts less than 10%. InSb, InP, or GaAs may also be included in the lead fluoride layer.
