Specification for Optical Sapphire Window:
Sapphire is a single crystal aluminum oxide (Al2O3). It is one of
the hardest materials. Sapphire has good transmission
characteristics over the visible, and near IR spectrum. It exhibits
high mechanical strength, chemical resistance, thermal conductivity
and thermal stability. It is often used as window materials in
specific field such as space technology where scratch or high
temperature resistance is required.
Sapphire glass are ideal for applications where high pressure, high
temperature, high thermal loads, vacuum, scratch resistance,
corrosion resistance, small coefficient of friction as well as
optical and insulating properties are a consideration.
-Sapphire windows normally need to work under extreme operating
conditions, so hard AR coating is required to withstand harsh
environmental conditions and improve resistance to scratching.
-Sapphire substrate has a high refractive index, thus usually
requires an antireflection coating on sapphire windows for
sufficient transmission in the region of interest.
