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
DLC (HC) coatings and Low Reflectance HC (LRHC)
Laser coatings for 1.064µ and 10.6µ
EUV coatings
Wide coatings catalog

Unbeatable coating performance, guaranteed:

Broadband AR: Ref<0.5% to 0.2% / Tra >98% to 99%
Broadband mirror: Ref>98% to 99%
Windscreen Wiper Test TS1888 / P 5.4.3 – DLC coatings
