ABSTRACT:
An anti-reflective coating employing Si.sub.1-x H.sub.x as a high refractive index material in a film pair together with SiO.sub.2 as a low refractive index material is found to be substantially transparent to visible light and to provide good anti-reflectance where the Si.sub.1-x H.sub.x film is ultra-thin, preferably less than about 80 Angstroms, and the thickness of the SiO.sub.2 film is matched to that of the Si.sub.1-x H.sub.x film. Laminated glazing units having such anti-reflective film can be used, for example, even in applications requiring high transmittance of visible light, such as motor vehicle windshields, in view of the substantial transparency of the coating.
