Abstract
An optical system includes an optical film curved about a first axis and a light control film curved about the first axis and substantially coextensive with the optical film. The optical film includes a first layer including a microstructured first major surface where the microstructured first major surface defines a linear Fresnel lens including a plurality of Fresnel elements extending along the first axis. The first major surface of the optical film faces the light control film. The light control film includes a plurality of spaced apart optically absorptive regions extending along the first axis and along a direction substantially normal to a major surface of the light control film. At least one of the optical film or at least one layer disposed between the optical film and the light control film includes at least one reflection mitigation element.
