Optical crystals are used as viewports to protect other components within an optical assembly, instrument, or laser. In certain applications, optical crystals are required to withstand harsh environmental conditions and provide high levels of performance and reliability.
sapphire crystal 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 crystal 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 anti reflection coating on sapphire crystal for sufficient transmission in the region of interest.
