Abstract: An optical component includes a substrate and a plurality of structures formed on a first major surface of the substrate and extending from the first major surface along a thickness direction of the optical component. The optical component can be assembled with another optical component to form a light control film. A light control film includes first and second optical components including respective pluralities of first and second structures formed on, and extending from, respective first and second substrates. The first and second optical components are assembled so that the first and second structures are disposed between the first and second substrates and interleaved to form a plurality of pairs of adjacent first and second structures. For each of at least some of the pairs, the adjacent first and second structures define an optical cavity therebetween substantially filled with a light absorbing material.

Abstract: A lightguide having opposing first and second major surfaces where the first major surface includes a plurality of extended features and a plurality of discrete features is described. The lightguide has a viewable area having a length at least 100 times a thickness of the lightguide. The extended features extend in a first in-plane direction across at least 90 percent of the length L of the viewable area. The discrete features are spaced apart along the length and width of the viewable area. The discrete features may be disposed in spaces between the extended features. The discrete features may have faces extending between and connecting adjacent extended features.

Abstract: A detector system is disclosed that includes a detector that is sensitive to wavelengths in a detection wavelength range. The detector system further includes a light control film that is disposed on the detector and includes a plurality of alternating first and second regions. Each first region has a width W and a height H, where H/W≥1. Each first region has a substantially low transmission in a first portion of the detection wavelength range and a substantially high transmission in the remaining portion of the detection wavelength range. Each second region has a substantially high transmission in the detection wavelength range.

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 includes a structured film and a light control film formed on the structured film. The structured film includes a substrate and a plurality of polymeric microstructures formed on a major surface of the substrate. Each microstructure includes an optical facet and a sidewall meeting the optical facet at a ridge of the microstructure. The light control film includes an optically transparent material disposed on and covering the plurality of polymeric microstructures, and a plurality of optically absorptive louvers formed in the optically transparent material opposite the structured film. The louvers extend along a longitudinal direction and are spaced apart along an orthogonal transverse direction. The louvers have an average depth D into the optically transparent material and have an average width W in the transverse direction. D/W can be greater than 2. The optical film is integrally formed.
