14DM-BBHR HR Broad Band mirrors
Standa
BBHR
產品特色
  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.
