Abstract
Dual-sided daylight redirecting films include an optical substrate with two solar light redirecting layers disposed on the major surfaces of the optical substrate. The light redirecting layers are microstructured surfaces forming a plurality of prism structures. At least one of the microstructured surfaces is an ordered arrangement of a plurality of asymmetric refractive prisms, and the two solar light redirecting layers are not identical or mirror images. Articles may be prepared that include the dual-sided daylight redirecting film and one or more glazing substrates.
