    • 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.

    • Multilayer reflecting polarizing films are disclosed having increased in-plane refractive index differences between adjacent microlayers along both the pass and block axis, and having negative refractive index differences between adjacent microlayers along the thickness or z-axis. Major front and back surfaces of the film exposed to air provide a Fresnel reflectivity component to the pass axis reflectivity, and the microlayers provide a microlayer component to the pass axis reflectivity, such microlayer component preferably having a reflectivity of p-polarized light that increases with incidence angle faster than the Fresnel reflectivity component decreases so as to substantially avoid off-axis gain peaks for p-polarized light. The films preferably utilize a relatively small total number of microlayers, arranged in a single coherent stack with monotonic optical repeat unit thickness profile, and at least some microlayers preferably include polyethylene naphthalate or a copolymer thereof.
    • 公开了多层反射偏振膜,其在沿着通过和阻挡轴的相邻微层之间具有增加的面内折射率差异,并且沿着厚度或z轴具有相邻微层之间的负折射率差异。 暴露于空气的薄膜的主要前后表面为通过轴反射率提供菲涅尔反射率分量,微层为通过轴反射率提供微层成分,这种微层成分优选具有随着偏振光的增加而增加的p偏振光的反射率 比菲涅耳反射率分量更快的入射角降低,从而基本上避免了p偏振光的离轴增益峰值。 薄膜优选利用相对较小的总数量的微层,其布置在具有单调光学重复单元厚度分布的单个相干叠层中,并且至少一些微层优选包括聚萘二甲酸乙二醇酯或其共聚物。
