Abstract
In one non-limiting embodiment, a transparency for use as a cover plate for a solar collector, window and/or room divider includes a major surface of a glass substrate having Brewster tetrahedrons to convert s-polarized light waves to converted p-polarized light waves to reduce the percent of light wave reflectance of the substrate. In another non-limiting embodiment, the transparency includes a major surface of the substrate having pyramidal tetrahedrons to capture light waves within the body of the substrate to reduce the percent of visible light reflection.
