  • 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.
