PROTECTIVE OPTICAL COATINGS

FOR SPACE, INDUSTRY, ASTRONOMY AND RESEARCH

 

CILAS offers protective optical coatings, either metallic or dielectric with accurate thickness and high uniformity. Magnetron sputtering deposition allows dense and efficient protection against severe environments such as solar illumination, humidity, atomic oxygen.

All these coatings are suitable for glasses, Zerodur®, SiC, titanium, CFRP, stainless steel and various aluminum types on components up to 2 meters by 2 meters.

Catalog optical coatings and specific designs available upon request.
