Provide an optimized performance at certain wavelength and certain angle of incidence (AOI)
	Coatings are provided by Ion Beam Sputtering (IBS) or Electron beam evaporation with/without Ion assistance coating techniques
	HR Laser Line coatings highly reflect wavelength range of <10% of the central wavelength (CWL). For instance, HR @ 800 nm will reflect wavelength range of 760 - 840 nm
	For wider wavelength range please refer to HR Broad Band wavelength (BBHR) coatings

HR Laser Line coatings provide an optimized performance at certain wavelength and certain angle of incidence (AOI). These multilayer coating stacks helps to achieve the highest possible reflectivity at specific laser line wavelengths at normal or 45 degrees incidence. HR Laser Line coatings are used 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. High reflectivity dielectric coatings in the range of 0.19 - 20 µm are available.
