Home > Dielectric Coated Optics > 14DM-BBAR - Broad Band AR coated windows
These coatings are designed to increase the transmission over a broad spectrum
Coatings are provided by Ion Beam Sputtering (IBS) or Electron beam evaporation with/without Ion assistance coating techniques
Broad Band Anti-Reflection Coatings in the range 0.19-10.6 µm are available

Broad Band AR coatings designed to reduce the reflectivity of a component to near-zero for Broad band wavelength range. We suplly standard Broad Band AR coatings in the range 0.19-10.6 µm. These multilayer broadband anti-reflective coating coating increases transmission of optical element for broad spectrum. Therefore, it is the ideal for a wide range of multiwavelength laser and white light applications. The wavelength range and reflectivity of the coating depends on the angle of the incident beam.
