AR Coatings

: Anti-Reflection Coating

 

AR Coating

As light passes through an uncoated glass substrate, approximately 4% will be reflected at each surface. This results in a total transmission of only 92% of the incident beam. Applying an AR coating on each surface will increase the throughput of the system and reduce hazards caused by reflections traveling backwards through the system (ghost images). Anti-reflection coatings are especially important if the system contains many transmitting optical elements.
