Thin-layer optical coating CERTESS® OPTAL

SURFACE TREATMENT FOR OPTICAL APPLICATIONS HEF has developed a thin multilayer PVD treatment, useful for optical coatings (reflectors, anti-reflective solutions) and offers a wide range of solutions. It's a range of thin films used for optical coatings such as reflectors, anti-reflective solutions and filters to provide a wide range of solutions for photonic components. Thin films deposited with very high thickness precision and well-controlled optical quality lead to very high reflective surfaces, used to design reflectors based on metal coatings or dielectric multilayers. Broadband anti-reflective coating using PVD coatings to reduce reflectance below 1% for almost all types of substrate (glass, PC, PMMA, etc.). This coating makes it possible to reconcile these various essential elements while providing other advantages linked to the implementation process: dimensional accuracy, gap quality, negligible effect on object mass, etc. Features : - Wide range of depositable materials: chrome, aluminum, gold, specific alloys - High purity of coatings - Control of thickness and surface finish - Resistance to chemical aggression (depending on filler materials) - Application on large parts Materials that can be treated: - Glass - Plastics - Organic matrix composites - Ceramics - Cermets - Metals and alloys Application examples: - Visors - Screens - Flacons - Architecture - Lenses
