Broadband AR coatings (SAR / BBAR)


Reflectance: Rave < 1.5% Rave < 0.5%
Damage Threshold: > 3 J / cm² @ 10 ns > 5 J / cm² @ 10 ns
Durability: MIL-C-675 MIL-C-675

  • Single Layer
  • Multilayer Broadband

Anti-reflection coatings are offered to reduce surface reflections to a minimum. Two types of broadband coating are offered. A single layer of MgF2 on Fused Silica or BK7 reduces reflections per surface to about 1.5% over a broad bandwidth. If lower reflectance is required a multilayer broadband coating will provide an average reflectance less than 0.5% per surface.

Part No.
