    摘要: The present application discloses filters and methods of making filters. In one aspect, a filter comprises a multilayer optical film (MOF) having a first reflection band, the MOF including distorted portions, the distorted portions having a second reflection band different from the first reflection band, a transparent outer layer disposed on a first side of the MOF, and an IR blocking material residing on the MOF and between the transparent outer layer and the MOF, wherein the IR blocking material is selectively disposed in the distorted portions. In another aspect, a method of producing a filter comprises the steps of providing a multilayer optical film (MOF) having a first reflection band, distorting portions of the MOF, the distorted portions having a second reflection band, different from the first reflection band, and transferring a layer of IR blocking material to the distorted portions of the MOF.

    摘要: An optical film is provided which comprises a disperse phase of polymeric particles disposed within a continuous birefringent matrix in combination with light directing materials to enable control of light emitted from a lighting fixture or display. The film is oriented, typically by stretching, in one or more directions. The size and shape of the disperse phase particles, the volume fraction of the disperse phase, the film thickness, and the amount of orientation are chosen to attain a desired degree of diffuse reflection and total transmission of electromagnetic radiation of a desired wavelength in the resulting film, and the light directing materials are chosen to control the direction of polarized light reflected from or transmitted by the optical film.
