Abstract
1325118 Optical apparatus POLAROID CORP 11 May 1972 22096/72 Addition to 1231143 Heading G2J In the window apparatus of Specification 1231143 is included a system for substantially reducing by absorbtion or reflection the transmission of infrared radiation through the apparatus. The absorption system may comprise dyes, e.g. bis-(as-1, 2-alkyl, hydrogen, aryl or heterocyclic) ethylene-1, 2-dithiolate)S. This may comprise a mixture of These dyes may be incorporated in a cellulose acetate butyrate protective layer. The reflective system may comprise a thin metallic infrared reflecting layer, e.g. gold incorporated between the wave plate and the transparent plastic support element next-adjacent thereto. Alternatively the rotatable polarizer member may comprise the infrared reducing system.
