sapphire waferis 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 wafercrystal window is intensively applied in high-tech
fields.
sapphire waferoptical 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.
Application
Sapphire is a hard crystal,it widely been used for watch and
mobilephone, Beauty equipment ,lasers,LED, and so on.
