Attention! You can customise this product to your needs.

These multilayer coatings are stacks intended to achieve the highest possible reflectivity at two 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.

varna The coatings are designed to achieve the highest possible reflectivity at two specific laser line wavelengths at normal or 45 degrees incidence
