摘要： An illumination light unit includes at least two light sources that generate light at different wavelengths. The illumination light unit also includes a reflecting cavity having one or more reflectors and a controlled transmission mirror disposed at an output of the reflecting cavity. The controlled transmission mirror includes an input coupling element, an output coupling element and a first multilayer reflector disposed between the input and output coupling elements. At least some of the light from the light sources is reflected within the reflecting cavity by the one or more reflectors and is mixed. Light passes out of the reflecting cavity through the controlled transmission mirror. The illumination light unit may be used for illumination purposes, or as part of a backlight for illuminating a display.

摘要： An optical imaging system including a wide-angle Cartesian polarizing beam splitter, light valve illumination optics having an f/#≦2.5, and at least one reflective light valve. The Cartesian polarizing beam splitter (PBS) has a structural orientation defining fixed polarization axes. The use of a Cartesian PBS allows the development of systems using curved PBS that provide higher light output and/or replace or augment other optical components. By recognizing and advantageously applying properties of wide-angle Cartesian polarizers, the present invention discloses a high-efficiency optical imaging system capable of functioning at f/#'s equal to or below f/2.5 while maintaining a contrast ratio of at least 100 to 1, or, more preferably, 150 to 1 in a projection system configuration.

摘要： Birefringent optical films have a Brewster angle (the angle at which reflectance of p-polarized light goes to zero) which is very large or is nonexistent. This allows for the construction of multilayer mirrors and polarizers whose reflectivity for p-polarized light decreases slowly with angle of incidence, are independent of angle of incidence, or increase with angle of incidence away from the normal. As a result, multilayer films having high reflectivity (for both planes of polarization for any incident direction in the case of mirrors, and for the selected direction in the case of polarizers) over a wide bandwidth, can be achieved.

摘要： A photosensitive element includes a layer of a photosensitive material on a transparent, multilayer, polymeric support having numerous alternating layers of at least two different polymeric materials. The polymeric multilayer support reflects at least 50% of actinic radiation in the range of wavelengths to which the photosensitive material is sensitive. If the polymeric multilayer reflector includes numerous, thin, alternating layers located at the surface of the polymeric support closest to the photosensitive material, the element not only provides increased speed but also provides an antihalation effect. In another aspect, a multilayer reflector is located a distance removed from the photosensitive layer sufficient to reduce any woodgrain that would otherwise occur, while increasing speed.

摘要： Reflective polarizers, which transmit one polarization and reflect the other polarization, have an extended red band edge in the off-axis transmission spectrum to control off axis color (OAC) hue. To control the OAC hue, the red band edge of the off-axis transmission spectrum, or OAC spectrum, is shifted beyond the boundary for red light, or to at least 600 nm. Even more preferably, the OAC spectrum is extended further into the red than any red emission peak of an associated lamp providing light into a system in which the reflective polarizer is used. The concept applies equally well to any type of reflective polarizer, such as multilayer reflective polarizers, cholesteric reflective polarizers, and the like. The resulting reflective polarizers are very useful for many different applications, such as liquid crystal displays.

摘要： In a multilayer dielectric reflector, treating the surface of the reflector selectively increases the amount of light transmitted through the reflector. Various surface treatments can be used to permit light to transmit through the reflector that would otherwise be reflected by the reflector. In one such reflector, different portions of the surface have different coupling efficiencies for coupling light having a high propagation angle into the multilayer reflector. Those portions having higher coupling efficiencies on each side of the reflector have a higher degree of transmission.
