METALLIC OPTICAL COATINGS
FOR SPACE, INDUSTRY, ASTRONOMY AND RESEARCH
CILAS offers a large range of metallic coatings manufactured with magnetron sputtering process.
- Silver coatings, protected and enhanced, meet reflectivity needs in visible range up to 16µm, for industrial and space programs.
- Aluminum coatings, protected and enhanced, meet reflectivity needs in lower spectral ranges, for industrial, space and astronomy programs.
- Bare gold coatings are a solution for electrical conductivity purposes, as well as reflectivity needs in IR range for industrial and space programs.
All these coatings are suitable for glasses, Zerodur®, SiC, titanium, stainless steel and various aluminum types on components up to 2 meters by 2 meters, and benefit from space heritage.
Catalog coatings and specific designs available upon request.
