  • Patent number: 9057843
    Abstract: A film construction (610) includes a group of microlayers that reflect normally incident light polarized along a first axis more than normally incident light polarized along a second axis. The microlayers are arranged into optical repeat units (ORUs) that have a layer thickness distribution along a thickness axis perpendicular to the first and second axes that provides the group of microlayers with an intermediate reflectivity over an extended reflection band for a given incidence condition. The ORUs include thinner ORUs whose thicknesses are less than an average thickness, and thicker ORUs whose thicknesses are greater than the average thickness. The group of microlayers is optically immersed in a medium having a refractive index greater than air, such that “supercritical light” can propagate through the microlayers. The microlayers are oriented such that, on average, the thinner ORUs are closer than the thicker ORUs to an output surface of the construction.
