摘要： Low loss, high reflectivity wide band mirror films provide a desired mix of specular reflection and diffuse reflection or scattering to provide semi-specular reflectivity. The mirror films generally include both a specularly reflective multilayer optical film (MOF) having a wide reflection band, and a scattering layer. In some cases a low refractive index TIR layer is sandwiched between the MOF and the scattering layer. In other cases the scattering layer contacts the MOF directly. In embodiments that include the TIR layer, the TIR layer preferably has a nanovoided morphology and includes a plurality of particles and a polymer binder. In embodiments wherein the scattering layer contacts the MOF directly, the scattering layer preferably also has a nanovoided morphology and includes a plurality of particles and a polymer binder.

摘要： An optical filter including a polymeric multilayer optical film is provided. The optical film has a reflection band having a reflection band edge that is, independent of location, one of a short wavelength band edge at a short wavelength side of the reflection band and a long wavelength band edge at a long wavelength side of the reflection band. The reflection band edge has a normal incidence reflection band edge wavelength that varies with location and that is a first wavelength at a first location and a second wavelength at a second location different from the first location. The first wavelength may be higher than the second wavelength by at least 2 percent.

摘要： A broadband mirror, polarizer, or other reflector includes at least one stack of microlayers. Microlayers in the stack are arranged into optical repeat units. At a design angle of incidence such as normal incidence, the stack provides a 1st order reflection band, a 2nd order reflection band, and optionally a 3rd order reflection hand. The 2nd order reflection band overlaps, or substantially overlaps, the 1st and/or 3rd order reflection bands to form a single wide reflection band. The wide reflection band may include the 2nd and 1st but not a 3rd order reflection band, or the 2nd and 3rd but not the 1st order reflection band, or it may include the 1st, 2nd, and 3rd order reflection bands, as well as still higher order reflection bands. The wide reflection band may cover at least a portion of visible and infrared wavelengths.

摘要： A broadband partial reflector includes a multilayer polymeric optical film having a total number of optical repeating units that monotonically increases in thickness value from a first side to a second side of the multilayer polymeric optical film. A baseline optical repeating unit thickness profile is defined by a first plurality of optical repeating units and having a first average slope, and a first apodized thickness profile of the multilayer polymeric optical film is defined by a second plurality of optical repeating units having a second average slope being at least 5 times greater than the first average slope. The second plurality of optical repeating units define the first side of the multilayer polymeric optical film and join the first plurality of optical repeating units. The second plurality of optical repeating units are in a range from 3-15% of the total number of optical repeating units.

摘要： First and second optical films in a stack each has a structured surface defining extended Fresnel lenses. First and second Fresnel lenses of the respective first and second films extend generally parallel to different first and second in-plane axes respectively. The films may be attached together such that light transmitted by one film is intercepted by the other. The film stack may also include a diffuser disposed to scatter light transmitted by the optical film(s). Other decorative articles include an individual optical film having a structured surface with transmissive facets arranged in a cyclic slope sequence from substantially zero to a maximum positive slope to substantially zero to a maximum negative slope and back to substantially zero, the sequence repeating over some or all of the structured surface. The slope sequence may define alternating focusing and defocusing Fresnel lenses, and the Fresnel lenses may be extended and linear.
