Optical multilayer anti-reflecting coating in the infrared range

Abstract

The constant expansion of the applicable scope of optical technologies has led to the need to create optical coatings not only with certain frequency characteristics, but also high performance properties. This article contains the results of a research of a thin optical film from an advanced material SrYF4. On the basis of this film, a multilayer coating was synthesized, which has high transparency in the near and middle infrared range. The coating has successfully passed the climatic tests on resistance to cold and heat.
