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.

Different from single layer MgF₂ broadband antireflective coating, the multilayer Broadband antireflective coating can reaches higher transmission for broadband spectrum. Therefore, it is the ideal for a wide range of multi-wavelength laser and white light application. Please notified that the wavelength range and reflectivity of the coating are obviously changed according to the incident angle.
