Abstract:
Light redirecting film articles include a microstructured optical film, such as a daylight redirecting film, bonded to another film. This type of assembly may serve various purposes. For example, the assembly may protect the structured film, provide additional functionality, such as diffusion or infrared reflection, and/or facilitate attachment of the microstructured optical film to a mounting surface, such as a glazing or window pane.
