CILAS is an expert in the design and manufacturing of optical thin film coatings. By using dense technologies, CILAS optical components ensure the highest performances in the most severe environments.

CILAS product line includes dielectric coatings, protective coatings, black coatings and metallic coatings for large size optics up to 2m x 2m, all suited for defense, space, astronomy, scientific and industrial applications.

CILAS operates dense coating technologies including the largest optical coating platform in Europe using magnetron sputtering and is equipped with state-of-the–art metrology and qualification means in cleanroom environment.

An experienced team is at your service from design to industrial production through project management, according to ISO standards.

CILAS offers protective 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 coatings and specific designs available upon request.
