METALLIC OPTICAL COATINGS

FOR SPACE, INDUSTRY, ASTRONOMY AND RESEARCH

 

CILAS offers a large range of metallic coatings manufactured with magnetron sputtering process.

  • Silver optical coatings, protected and enhanced, meet reflectivity needs in visible range up to 16µm, for industrial and space programs.
  • Aluminum optical coatings, protected and enhanced, meet reflectivity needs in lower spectral ranges, for industrial, space and astronomy programs.
  • Bare gold optical coatings are a solution for electrical conductivity purposes, as well as reflectivity needs in IR range for industrial and space programs.

All these optical 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 optical coatings and specific designs available upon request.
