AR coating, refers to Anti-Reflection coating, it is used to reduce the reflected ray that occurs at the interface of the optics.

AR coating are used for two particular objectives :

  • Increase the signal transmission so reduce loss of a system.
  • Avoid reflection of an image on the optics that may cause interference with sensors (eye or other).

AR coating is usually done by thin layer coating. It can be single layer or multi layer according to the range of wavelength to be effectively reached.

The working process is to create an orthogonal opposed signal at the interface of the layer to the reflective signal at the interface of the optics that cancels the latter one.
