For the physical characteristics of sapphire glass have a high temperature resistance of 2000 degrees and 9.0 hardness ,85%transmittance；
it is gradually replacing the transparent glass such as quartz glass and Corning glass because of the trend of lower and lower materials price.
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.
