HR Broad Band mirrors (BBHR)

HR Broad Band mirrors (BBHR) provide an optimised performance at broad wavelength range.

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.
If your application do not require such wide wavelength range to be reflected please refer to - Laser Line HR wavelength (HR) coatings.
