Abstract

ИНТЕРФЕРЕНЦИОННЫЙ ФИЛЬТР, состо щий из подложки с многослойным покрытием, выполненным из чередующихс  слоев материалов с высоким и низким показател ми преломлени , причем в качестве материала с высоким показателем преломлени  использован германий, отличающийс  тем, что, с целью увеличени  влагостойкости и механической прочности, слой с низким показателем преломлени  вьтоЛнен из фтористого иттри , а слои с высоким и низким показател ми преломлени  разделены прослойкой из трехсернистой сурьмы с оптической толщиной INTERFERENCE FILTER, consisting of a substrate with a multilayer coating made of alternating layers of materials with high and low refractive indices, moreover, germanium is used as a material with high refractive index, characterized in that, in order to increase the moisture resistance and mechanical strength, a low refractive index was extracted from yttrium fluoride, and the layers with high and low refractive indices were separated by a layer of three-sulfur antimony with an optical thickness
