Sapphire crystal for infrared transparent
window needs to be high qualified, and should meet the basic requirements as
following:
1)High mechanical strength: infrared transparent window material should have sufficient
strength, so that it can withstand the high-speed movement of the pressure
load.
2) High thermal stability: can withstand the impact of aerodynamic heating and high temperature caused by the change, transmittance and refractive index by the temperature changes.
3) High chemical stability: the material is exposed to the air, so that the material should be able to prevent salt solution or etching gas corrosion, and should not be easy deliquescence
4) High optical transmittance: can efficiently transmit the ultraviolet to the infrared radiation
5) High optical properties: small optical scattering and good refractive index
6) Meet requirement of large size window

The main part for growing sapphire is
tungsten crucible, which can be customized.
