An ultra hard, wideband anti-reflection coating for an IR window, such as GaAs, which resists environmental and chemical attack. The coating is designed to allow spectral transmission therethrough in a wide band, namely the 3 to 12 micron range. A cladding layer is formed on the GaAs window. A first diamond like carbon (DLC) layer is then formed on the first bonding layer. A bonding layer is formed on the first DLC layer and a second DLC layer is formed on the bonding layer.
