AR Coatings                                                                          

AR coatings can be used to reduce reflection from the surface of an optical component so as to improve the performance at a specific wavelength or over a waveband. Our capabilities in anti-reflection coatings range from single layer to multilayer, all characterized by their high efficiency, mechanical durability and environmental stability. AR coatings generally fall into four basic categories.


Indices of Substrates: From 1.52 to 2.1
Residual Reflection: approx. 1.5% reflection for BK7 at center WL

Single Layer MgF2 AR Coatings

Single layer MgF2 coating is used when a slight improvement is needed in reducing the surface reflection of an optical element. It is broader than a "V" type coating, allowing for use across wider wavelength bands, or over higher incident angles, i.e. it is not so sensitive to incident angle.

Multilayer "V" AR Coatings

Multilayer "V" AR coatings offer a very low residual reflection at a particular wavelength for most laser applications.

Minimum Reflection < 0.1% at the specified wavelength
Center Wavelength: From 300nm to 2000nm

Multilayer Broadband AR Coatings

Multilayer broadband AR coatings can efficiently reduce surface reflection of optical components and give excellent performance in improving transmission over a wide bandwidth.

  Indices of Substrates: From 1.47 to 1.80
  Center Wavelength: From 250nm to 3000nm
  Substrates: Glass, silicon, germanium and other materials
  Maximum Single-Surface Reflection : < 0.5%
  Average Single-Surface Reflection: < 0.25%

Dual-Wavelength AR Coatings

Dual wavelength AR coatings can offer very low reflection or very high transmission for two separate wavelengths, such as 532nm/1064nm and 633nm/1064nm. This coating is often applied to frequency doubling laser systems and light with two or more separate wavelengths.
