IR Anti-Reflection Coatings
IR Anti-Reflection coatings from 2-12µm are available for deposition onto Infrared Materials including:
Silicon - Germanium - Zinc Selenide - Zinc Sulfide - CaF2 -
- BaF2 - Gallium Arsenide - Sapphire - IR Fused Silica
ECI offers an extensive range of Anti-Reflection (AR) coatings for maximum performance in the 3-5µm, 8-12µm and 3-12µm regions. ECI's durable AR coatings provide excellent transmission over the respective spectral band. These broadband AR coatings have less than 1% average reflectance per surface. Our narrow band or V-coat AR coatings are designed to reduce per surface reflections to less than 0.50%.
Coatings are optimized for angle of incidence, substrate index of refraction, incident medium and bandwidth regions.
NEW PRODUCT:
ECI's triple band V-coat reduces surface reflections to < 0.5% over three distinct laser wavelengths, available for deposition on all IR optical infrared materials.
All coatings meet or exceed the adhesion, abrasion, humidity & temperature influence tests of MIL-C-48497.
• Typical Anti-Reflection Coatings for Infrared Optical Materials:
reflectance is per surface @ 0° A.O.I.
