Sapphire is a single crystal aluminum oxide (Al2O3). It is one of
the hardest materials. Sapphire has good transmission
characteristics over the visible, and near IR spectrum. It exhibits
high mechanical strength, chemical resistance, thermal conductivity
and thermal stability. Sapphire optical windows are ideal for
applications where high pressure, vacuum, or corrosive atmospheres
are a consideration. It is also resistant to UV radiation
darkening.
Optical windows are applied for protecting fragile optical
components inside an equipment or directly used for watching
windows because of its very good physical property.
they are adopted to isolate two physical environments while
allowing light to pass. Optical Sapphire windows refer to a piece of transparent optical
material that allows light into an optical instrument. They are
pieces of optical glasses with ground and polished faces that are
relatively parallel.
