Optical Coatings

The most advanced optical coatings, developed by world-leading experts

With over 40 years of experience, Ophir is recognized as a world leader in the development, production and application of advanced optical coatings. Our highly abrasion-resistant, anti-reflective (AR) coatings include several types of HC coatings which provide maximum durability, energy transmission & minimal reflection.

PVD thermal evaporation (resistance heating and electron-gun coating)
PECVD (plasma-enhanced chemical-vapor deposition)
IAD (ion gun)

Innovative technologies for coating success:

Physical Vapor Deposition (PVD) – Thermal heating and electron gun
Ion Assisted Deposition (IAD) – Ion gun
Plasma Enhanced Chemical Vapor Deposition (PECVD) for DLC coatings
Short radius surfaces coatings

Meeting coating requirements for every component:

Anti-reflective(AR), Mirrors and Filters
UV, VIS, NIR, SWIR, MWIR, LWIR
Multispectral coatings
High efficacy and high durability coatings
