Filters transparent to near-infrared radiation

Filters transparent to near-infrared radiation. (Mitsubishi Rayon Co., Ltd., Japan). Jpn. Kokai Tokkyo Koho JP 59010909 A2 20 Jan 1984 Showa, 5 pp. (Japanese). (Japan). CODEN: JKXXAF. CLASS: IC: G02B005-22; G02B001-04; H01L031-02. APPLICATION: JP 82-120935 12 Jul 1982. DOCUMENT TYPE: Patent CA Section: 38 (Plastics Fabrication and Uses) Section cross-reference(s): 41 Optical filters which block out visible light while allowing near-IR radiation (700-1600 nm) to pass through are manufd. from near-IR transparent polymers contg. 0.01-1.0% Cu phthalocyanine compds. and optionally 0.02-0.1% azo and/or diazo dyes. Thus, Novalex 7030 [90803-65-9] (polycarbonate resin) 100, ANC 510 Green [90804-10-7] (modified Cu phthalocyanine pigment) 0.2, and Ceres Red B [3176-79-2] 0.05 kg were mixed and extruded into sheets 2 mm thick, which had transparency >80% at >800 nm and ~0% at <700 nm.
