Radiation Hard Multi-Layer Optical Coatings, Phase I

Completed Technology Project

Project Description

Radiation Hard Multi-Layer Optical Coatings, Phase I
Next generation space telescopes require advanced optical coatings to provide low loss transmission of light in a variety of spectral ranges and protect optical components from damage in a space environment. In this SBIR program Nanohmics proposes to examine uses of amorphous nitrides and oxides as a high quality, long lived coating for production of wide-acceptance angle IR anti-reflection and band-pass coatings on optical components. Amorphous nitrides are hard, flexible wide-bandgap semiconductor materials that can be used as an optical coating. Alternating layers of high index nitrides such as AlN combined with low index oxides such as SiO2 can be used to make good wide acceptance angle anti-reflective coatings for a variety of optical components.
