Thin-Film Coated Glass Filters

Reflective thin-film coated laser safety filters

We apply high reflection layers for laser protection on our glass filters. The thin-film coating is typically applied on the laser side of the filter to optimize the wavelength blocking range and to further increase the protection of the filter. In case of a direct laser hit, the energy from the laser light is reflected by the coating and does not enter the filter. Subsequently, this provides exceptionally high protection levels for reflective coated laser safety filters.



  • Multi-wave protection
  • Narrowband protection
  • High Optical Density (OD)
  • Excellent visible light transmission (VLT)
