We suplly standard Broad Band AR coatings in the range 0,19 um 10,6 um.
These multilayer broadband anti-reflective coating can higher transmission access a broad spectrum. Therefore, it is the ideal for a wide range of multi-wavelength laser and white light applications. Please notified that the wavelength range and reflectivity of the coating changes according to the angle of the incident beam.
Coatings are provided by Ion Beam Sputtering (IBS) or Electron beam evaporation with/without Ion assistance coating techniques.

These coatings are designed to increase the transmission over a broad spectrum |
