Abstract:
Light management film constructions contain a first optical film 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 3 or greater sides. A second optical film contacts and is bonded to substantially all of the structures of the first major structured surface of the first optical film. The light management constructions can be incorporated into optical articles such as windows.
