For industry

With cutting-edge capabilities and experience, CILAS is the expert for industrial programs.

CILAS designs and manufactures specific dielectric coatings for industrial applications, such as the display screen market on large dimension windows, from 1m to 1.8m long.

For astronomy

CILAS has manufactured various complex components integrated into telescope instrumentations, like IRDIS and CPI instruments for SPHERE of ESO's Very Large Telescope.

In order to meet the requirements of worldwide astronomers, CILAS relies on its expertise and a large range of production equipment.

For space

CILAS has been involved in ambitious missions like Chemcam for the NASA Curiosity Rover, satellite programs such as COMS with AIRBUS DS, Sentinel 2 with ESA, Proba-V with AMOS, TROPOMI with SRON etc…

CNES and AIRBUS DS have entrusted CILAS and WINLIGHT with the design and manufacturing of the optical components for the Microcarb Instrument, aimed at measuring the global CO2 distribution in the atmosphere.

All this was adressed by CILAS thanks to the dense coating technologies used: Ion Assisted Deposition (IAD) and Dual Ion Beam sputtering (DIBS)
