Why Anti Reflective Coated Glass is Everywhere

An anti-reflective (AR) coating is a type of optical coating applied to the surface of lenses and other optical elements to reduce reflection.

Diamond AR is a conductive anti-reflective coating for glass, acrylic and polycarbonate substrates. The coating has a typical sheet resistance of 1000+ ohms/sq and spectral properties similar to those of Diamond Coating’s Diamox+ coating. The spectral properties offered by our Diamond AR anti-reflective coating for glass are comparable to the properties of our Diamox+ coatings, making it the perfect solution to a comprehensive range of applications.

An anti-reflective (AR) coating is a type of optical coating applied to the surface of lenses and other optical elements to reduce reflection. In typical imaging systems, this improves efficiency since less light is lost due to reflection. In complex systems such as telescopes and microscopes, the reduction in reflections also improves the contrast of the image by elimination of stray light. This is especially important in planetary astronomy.

In other applications, the primary benefit anti-reflective coated glass is the elimination of the reflection itself, such as a coating on eyeglass lenses that makes the eyes of the wearer more visible to others, or a coating to reduce the glint from a covert viewer’s binoculars or telescopic sight.

Our Anti-Reflective Coating is also widely used on Cinema Projector Portal Glass. Click the link to find out why our coating is used to protect cinema’s most valuable asset.


Diamond AR VAC – Boasting an average reflection of 0.5%, this vacuum-deposited coating offers varying wavelengths to meet customer needs

Diamond AR COND – A multi-layer AR coating combined with a conductive ITO coating.

An anti-reflective (AR) coating is an optical coating used in applications involving light passing through surfaces. Primarily designed to reduce reflection, these coatings also improve the:

  • The efficiency of typical imaging systems, as light loss due to reflection is reduced
  • The contrast of images in complex imaging systems by eliminating stray light

Applications of AR coated glass may, for example, include:

  • Camera Lens Elements
  • Solar Cells
  • Ophthalmic (corrective) lenses
  • Microelectronic Photolithography
  • Microscopes
  • Telescopes
  • Binoculars and More

Combining anti-reflective coatings with conductive ITO (Indium Tin Oxide) coatings makes coated glass suitable for applications including:

  • Aircraft Instruments
  • Conducting Glass
  • LCD TV’s
  • Microscope Slides
  • Other Display Technologies
  • Touch Sensitive Panels
  • Transparent Shielding Glass and More

Improving the light transmission and subsequently the quality of projected images, anti-reflective coatings are also an important addition to cinema projection portal windows.
