Abstract

FIELD: optical instruments. SUBSTANCE: structure of lens coating, which total optical depth is less than quarter of operational wave length, is SKLKH, where S is substrate which refraction index is in range of 2.2 -- 4.0. Layer with high refraction index is made from zinc sulfide (ZnS) or zinc selenide (ZnSe). Layer with low refraction index is made from bismuth fluoride (BiF). In addition adhesion layer of ZnS or ZnSe is introduced between substrate and coating. optical depth of introduced layer is (0.1-0.2) of quarter of wave length. EFFECT: increased field of application, increased environment protection for production of coating and consuming waste.

Просветляющее покрытие относится к области оптического приборостроения, в частности к оптическим покрытиям, и может быть использовано для создания проходных оптических элементов из полупроводниковых материалов, в том числе для ИК лазерных систем. Цель - универсальность конструкции, улучшение экологической обстановки при производстве покрытий и утилизации отходов. Указанная цель достигается тем, что в просветляющем покрытии вида П К1Н К2В с суммарной оптической толщиной, не превышающей четверти рабочей длины волны, где П - подложка с показателем преломления от 2,2 до 4,0, слой с высоким значением показателя преломления выполнен из сульфида (ZnS) или селенида цинка (ZnSe), слой с низким значением показателя преломления выполнен из фторида висмута (BiF3) а между подложкой и покрытием введен адгезионный слой из ZnS или ZnSe оптической толщиной (0,1 - 0,2) четверти длины волны.Antireflection coating refers to the field of optical instrumentation, in particular to optical coatings, and can be used to create pass-through optical elements from semiconductor materials, including for IR laser systems. The goal is the universality of the design, improving the environmental situation in the production of coatings and waste disposal. This goal is achieved by the fact that in the antireflection coating of the form P K 1 N K 2 V with a total optical thickness not exceeding a quarter of the working wavelength, where P is a substrate with a refractive index of 2.2 to 4.0, a layer with a high value of the index the refractive index is made of sulfide (ZnS) or zinc selenide (ZnSe), the layer with a low refractive index is made of bismuth fluoride (BiF 3 ) and an adhesive layer of ZnS or ZnSe with an optical thickness of 0.1 to 0.2 is introduced between the substrate and the coating ) quarter of the wavelength.
