AR Coatings for Glass

Anti reflection coatings reduce first surface reflection losses, improve contrast and boost the transmission through your optical surface. Choose from a typical design below or ECI will design and deposit a custom glass anti-reflection (AR) coating for your specific window or lens application. If you are not sure how to specify your coating, our design team will work with you to identify the optimum design for your system.

Custom and standard anti-reflection coatings from super low narrow band to extended high performance broadband are available for deposition on all types of glass substrates including:

Fused Silica
Precision Glass Optics
Molded Glass Elements
High Expansion Glasses
Gradient Index Glass
CaF2
BaF2
High Stain Glasses
Ball lenses
Ultra Thin Wafers
High Index Glasses

ECI‘s coating designs can be optimized for maximum performance from the 200nm – 2500nm wavelength region. Specify your particular wavelength range, angle of incidence, substrate index of refraction, incident medium and polarization requirements to ensure maximum transmission for your system. Designs include V-coats, broadband, super broadband, dual band and narrow band coatings.

Glass Anti-Reflection coatings are utilized in a variety of applications. It is very common for these coatings to be used in laser applications. In such cases, they will need to meet or exceed certain LDT ( Laser Damage Threshold ) requirements. ECI primarily uses Ion Beam Sputtering ( IBS ) or Electron Beam ( E-Beam ) to deposit AR coatings that must withstand high power lasers. ECI deposits High Power Glass AR coatings on various substrates including: Glass/Fused Silica windows, lenses and wafers, Fiber optic cables and assemblies, LBO, BBO, KTP, TGG, GGG, BiG, and Silicon wafers.
