HR Laser Line mirrors (HR)

HR Laser Line mirrors (HR) provide an optimised performance at certain wavelength and certain angle of incidence (AOI).

These multilayer coatings are stacks intended to achieve the highest possible reflectivity at specific laser line wavelengths at normal or 45 degrees incidence. Laser line high reflectivity coatings are intended for external beam manipulation applications where even slight losses may be intolerable.

Coatings are provided by Ion Beam Sputtering (IBS) or Electron beam evaporation with/without Ion assistance coating techniques.


HR Laser Line coatings (HR) highly reflect wavelength range of <10% of the central wavelength (CWL). For instance, HR@800nm will reflect wavelength range of 760-840nm.
If your application needs to reflect wider wavelength range please refer to - Broad Band HR wavelength (BBHR) coatings.
