Attention! You can customise this product to your needs.
These multilayer coatings offers high reflectivity for broad spectrum. Therefore, it is the ideal for a wide range of multi-wavelength laser or white light applications.
Coatings are provided by Ion Beam Sputtering (IBS) or Electron beam evaporation with/without Ion assistance coating techniques.
Broad Band HR coatings (BBHR) can highly reflect wavelength range of 10% of the central wavelength (CWL). For instance, BBHR @ 800nm can reflect wavelength range of 750-850nm or even wider upon request.
varna Provides an optimised performance over broad wavelength range
