Abstract:
Light management constructions contain an optical substrate having a first major surface and a second major surface opposite the first major surface. The first major surface is a microstructured surface with asymmetrical structures. The asymmetrical structures form an ordered arrangement of a plurality of multi-sided refractive prisms, with the multi-sided refractive prisms having a cross section of 4 or greater sides. The light management constructions can be incorporated into optical articles such as windows.
