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.
