Abstract: The present disclosure provides a light control film that is capable of transmitting light, or allowing a viewer to observe information, only within a viewing region centered around the normal (perpendicular line) to a surface. The light control film generally blocks information or light outside of this viewing region, and provides security in all directions including right-and-left and up-and-down of the film. The light control film includes a plurality of light-transmissive cavities that are surrounded by a light absorbing material, such that each of the plurality of cavities is optically isolated from adjacent cavities. Each of the light-transmissive cavities effectively block light which enters the cavity outside of a viewing (that is, cutoff) angle.

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.

Abstract: A light redirecting film includes a first layer disposed on a second layer with structured major surfaces of the first and second layers facing each other. An optically reflective layer or a metal layer is disposed between the first and second layers. The first layer can be a hot melt adhesive layer and the second layer can be a polymeric layer. The first and second layers can be unitary layers. The first layer can be a first polymeric layer having a softening temperature T1 and the second layer can be a second polymeric layer having a softening temperature T2 greater than T1. Heating and/or applying pressure to the film changes an optical characteristic of the film by less than about 5%.

Abstract: A detector system is described 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: A retroreflective system is disclosed that includes a retroreflective sheet for retroreflecting light, and a light control film disposed on the retroreflective sheet. For a first wavelength, light incident on the light control film at each of a first and second angles of incidence is retroreflected. For a second wavelength, light incident on the light control film at the first, but not the second, angle of incidence is retroreflected.
