ABSTRACT:
An external window for infrared radiation is protected from hostile environments by forming a bulk window of gallium arsenide and depositing a protective layer of silicon on the external surface. A grid-like pattern of conductive lines is formed in the silicon layer to provide a heated de-icer and to act as a shield against longer wavelength electromagnetic radiation.
