Standa
14DM-HR
- Provide an optimised 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 (HR) highly reflect wavelength range of <10% of the central wavelength (CWL). For instance, HR@800nm will reflect wavelength range of 760-840 nm
- If your application needs to reflect wider wavelength range please refer to - Broad Band HR wavelength coatings
- Our standard substrates can be coated with this type of coatings
HR Laser Line mirrors (HR) 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. Laser line HR 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.
