Abstract
A protective cover (10) for an optical device, such as a spatial light modulator or an infrared detector or receiver. The cover (10) has an optically transmissive window (11), which has a coating (12) on one or both of its surfaces. The coating (12) is made from a halogenated material, which is deposited to form a chemical bond with the surface of the window (11).
