Description

Window is a piece of glass with plane parallel surfaces. It is used to isolate different physical environments while allowing light to pass. The environments may vary widely in temperature, pressure, chemical composition, phase or cleanliness. When selecting the appropriate windows the optical, mechanical and thermal properties must be considered according to the intended use.
