Coatings
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 light. Anti-Reflection (AR) coatings are especially
important if the system contains many transmitting optical elements. Coating
each component will increase the throughput of the system and reduce hazards
caused by reflections travelling backwards through the system (ghost images).
Many low-light systems incorporate AR coated optics to allow for an efficient
use of the light. We now can provide many kinds of anti-reflective, high
reflective and partially reflective coatings.
