IR cut filters for optoelectronic devices, based on CdSb, ZnSb single crystals

Abstract

Interference-adsorptive filters on the base of the CdSb and ZnSb semiconductor single crystals are proposed as a new type of cooling cut optical filters used in modern optoelectronics. Computer simulation of the structure of interference multilayer coatings has shown the availability of design and application of cut filters on CdSb with optimized parameters. Experimental results demonstrate high optical characteristics and mechanical strength of two-channel cut CdSb filters used in various devices.
