ANTI-REFLECTIVE TRANSPARENT COATING

摘要

An anti-reflective coating employing Si1-xHx as a high refractive index material in a film pair together with SiO2 as a low refractive index material is found to be substantially transparent to visible light and to provide good anti-reflectance where the Si1-xHx film is ultra-thin, preferably less than about 80 Angstroms, and the thickness of the SiO2 film is matched to that of the Si1-XHx film. Laminated glazing units having such antireflective 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.
