Abstract
A multilayer antireflection coating for a temperature sensitive substrate such as plastic. One layer is a DC reactively sputtered metal oxide which may be deposited quickly and without imparting a large amount of heat to the substrate. Another layer has a refractive index lower than the substrate.
