Home > Dielectric Coated Optics > 14DM-BBHR HR Broad Band mirrors

		Provide an optimised performance over broad wavelength range

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

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

		Any other our standard substrate can be coated with this type of coatings!

HR Broad Band mirrors (BBHR) provide an optimized performance at broad wavelength range. These multilayer coatings offer 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. High reflectivity dielectric coatings in the range of 0.19 - 20 µm are available.
