Abstract
Материал фототропного затвора для оптических усилителей на неодимовом стекле на основе производного ацетата целлюлозы с введенным в него полиметиновым красителем, отличающийся тем, что, с целью устранения оптических аберраций, увеличения оптической однородности и степени просветления, в качестве производного ацетата целлюлозы использован диацетат целлюлозы с содержанием уксусной кислоты 54 - 55%, вязкостью 23%-ного раствора 500 - 750 с и содержанием низкомолекулярных фракций не более 7%, а полиметиновый краситель имеет строениегде А - галоген, арил или -ОСОСН;В - арил;Z - -(СН)-, -(СН)-, СН-О-СН-;Х - анион.Phototropic shutter material for neodymium glass optical amplifiers based on cellulose acetate derivative with polymethine dye introduced into it, characterized in that cellulose diacetate containing acetic acid is used as a cellulose acetate derivative to eliminate optical aberrations acids 54 - 55%, a viscosity of a 23% solution of 500 - 750 s and a content of low molecular weight fractions of not more than 7%, and the polymethine dye has a structure, where A is halogen, aryl or -OCOCH; B is aryl; Z - - (CH) -, - (CH) -, CH-O-CH-; X is an anion.
