What is a Thin Film Optical Coating?


Thin film optical coatings are applied to optical substrates such as glass to alter or change its optical properties. The coating is applied in extremely thin layers to the surface and the number of coatings and the thickness of the coating is done to effect a specific wavelength of the light. Thin Film Optical Coatings from Abrisa Technologies are applied via electron beam and ion-assisted electron beam deposition influencing and controlling reflectance, transmittance, absorbance and resistance.


Thin Film Optical Coatings include:


  • Indium Tin Oxide (ITO)
  • Index-Matched Indium Tin Oxide
  • Front & Back Surface Mirrors
  • Dichroic Filters
  • Band-pass Color Filters
  • AR – anti-reflective Coatings
  • Beam Splitters
  • Metal Coatings
  • Precision Hot Mirrors
  • Cold Mirrors
  • Neutral Density Filters
  • Infrared or IR Filters
  • Ultraviolet UV Filters


The thin film multi-layer coatings can be applied to glass substrates as thin as 70 microns and as small as 0.1” and as thick as 6” and in diameters up to 36”.
