| 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. AR (antireflection
coatings) coatings are especially important
if the system contains many optical
elements. Coating each component will
increase the throughput of the system and
reduce hazards caused by reflections
traveling backwards through the system
(ghost images) .
China Optical Coatings laboratory provide
following AR Coatings Services:
Substrates:
Glass, quartz, sapphire, ruby, YAG, silicon,
germanium, zinc selenide, zinc sulphide, and
other optical crystals.
