Anti-Reflection Coatings for Glass

Anti-Reflection 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 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 reflective 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 240nm - 2400nm 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.

Applications include: miniature optics, display windows, industrial instrumentation, medical optics, port windows, and fiber optic and laser components.

ECI's anti-reflection coatings meet the reflection and environmental requirements of MIL-C-14806A and MIL-C-48497. Designs comply with military and telecommunication industry standards.

Examples of LDT

High Laser Damage Threshold Anti-Reflection Coatings
WavelengthLDT*Pulse width
355 nm 4 J/cm2 10 ns
532 nm 9 J/cm2 10 ns
1064 nm 40 J/cm2 10 ns
