2inch M-axis 0.5mm thickness sapphire wafer for epi-ready test
,sapphire optical windows, M-axis 2inch sapphire epi-ready
substrate
1. Description
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.
sapphire application: sapphire optical lens ,sapphire ball,
sapphire bearing ,sapphire led wafer, sapphire watch glass lens.
