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.

Abstract: An optical system includes an optical film curved about a first axis and a light control film curved about the first axis. The light control film can be disposed between a light source and the optical film. The optical film includes a microstructured first major surface and an opposing second major surface. The microstructured first major surface defines a linear Fresnel lens including a plurality of Fresnel elements extending longitudinally along the first axis. The first major surface of the optical film faces the light control film. The light control film can include a plurality of alternating optically transmissive and optically absorptive regions extending longitudinally along the first axis such that in a cross-section orthogonal to the first axis, for at least a majority of the optically transmissive regions, a centerline between adjacent optically absorptive regions is substantially normal to a major surface of the light control film.

Abstract: An optical film having a first surface, an opposing second surface, and a thickness normal to the first and second surfaces is cut. Cutting the film forms a channel at least partially through the thickness of the film. A light control material is printed proximate to a surface of the film. The ink traverses through the channel by capillary motion.

Abstract: An integral multilayer optical construction includes opposing first and second structured major surfaces having two-dimensional arrays of respective first and second structures. An optical diffuser is embedded within the optical construction between the first and second structured major surfaces. The optical diffuser has an optical haze of greater than about 5% for at least one visible wavelength in a visible wavelength range extending from about 420 nm to 680 nm. When the optical construction is disposed on a light source with one of the first and second structured major surfaces facing the light source, light emitted by the light source is transmitted by the optical construction with a cross-section of an angular luminous distribution of the transmitted light in at least one first plane that includes a normal to the optical construction, including first and second intensity peaks at respective first and second angles on opposite sides of the normal.
