1. what is sapphire glass?
Sapphire is one of the hardest materials, and possesses very good
transmission
during the range of visible and near IR spectrum.
It is widely used as optical window in infrared and far infrared military equipments,
apparatus and instruments of satellite and space technology, and navigation and
spaceflight, such as night infrared scope/sight and night vision camera, etc.
The sapphire crystal window is intensively applied in high-tech
fields.
Sapphire optical windows are ideal for applications where high
pressure, vacuum,
or corrosive atmospheres are a consideration. Sapphire, a single crystal form of Al2O3,
is resistant to attack by strong acids due to its high dielectric constant. It has high
compressive strength and a high melting point. It is also resistant to UV radiation darkening.
