| An optical thin film stack provides reflection of essentially all light except for a selected amount of transmission over a selected wavelength range. Reflecting, rather than absorbing, unwanted light avoids heating caused by light absorption and allows productive use of the non-transmitted light in some applications. In some embodiments, reflector designs are “stacked” on an optical substrate to provide serial optical reflectors. Stacking dichroic filters provides reduced sensitivity to cone angle and manufacturing advantages. | ||||||

| PURPOSE: To enable simple and efficient production of the titled filter by a method wherein transparent thermoplastic resin in which a small portion of carbon black is dispersed is used as the intermediate layer and thermoplastic resin excellent in transparency is used as both outside layers to make three layers. CONSTITUTION: Coextrusion is performed by the outer layers 1, 3 made from thermoplastic resin excellent in transparency and the intermediate layer 2 where a small portion of carbon black is dispersed in above-said resin. As carbon black are used common carbon black such as furnace black, acetylene black, channel black etc. As thermoplastic resin excellent in transparency, polystylene, polymethyl methacrylate, polyamide, polycarbonate, polymethyl pentene, stylene acrylonitrile copolymer are enumerated. However, in transparency for an ND filter, impact resistance, further, film moldability, polymethyl pentene and polycarbonate are most desirable. By this manufacturing method productive cost is lowered and each hue in the visible light range can be absorbed on an average. COPYRIGHT: (C)1986,JPO&Japio | ||||||

| A spectral reflectance in the entire visible wavelength range may be decreased to decrease inconveniences in an image such as flare or ghost. A non-reflective periodic layer including a large number of fine uneven periodic structure bodies is formed on a substrate, and a neutral density (“ND”) film is formed on the other surface of the substrate by vacuum deposition, to improve an anti-reflection function. Regarding a beam entering the ND filter, the MgF2 film of the formed ND film suppresses the spectral reflectance at the boundary of the atmosphere and the ND film and at the boundary of the ND film and the substrate. The non-reflective periodic layer decreases the reflectance at the boundary of the substrate and the atmosphere. | ||||||
