    摘要： An optical construction includes an optical film including a plurality of polymeric layers and an optical retarder disposed on the optical film. For a substantially normally incident light and for a visible wavelength range of about 420 nm to about 680 nm and an infrared wavelength range of about 900 nm to about 1100 nm: for the incident light polarized along each of mutually orthogonal in-plane first and second directions. the plurality of polymeric layers has an optical transmittance of greater than about 60% for at least one visible wavelength in the visible wavelength range and an optical reflectance of greater than about 60% for at least one infrared wavelength in the infrared wavelength range. For the incident light polarized along at least one of the first and second directions, the optical retarder has an optical retardance of greater than about 1000 nm at the at least one visible wavelength.

    摘要： A system for measuring dimensions of film to be applied to a window includes a plurality of removable cards for placement on the window, each of the plurality of removable cards having a plurality of visible correspondence points at pre-defined positions on the respective removable card. The system further includes a mobile device having an image capture device, and the image capture device is configured to capture an image of the window having a set of correspondence points visible in the image. Additionally, the system includes a server configured to receive the image of the window captured by the mobile device and process the image to determine dimensions of a film to be cut for the window based on the set of correspondence points and the pre-defined positions, and processing the image removes perspective distortions in the image. The system is configured to output the dimensions of the film.

    摘要： A multilayer optical film includes a plurality of optical repeat units where each of the optical repeat units includes at least individual first and second layers. The first and second layers in each of the optical repeat units have respective indices of refraction n1 and n2 and corresponding respective f-ratios f1 and f2 along a same in-plane first direction for a same first visible wavelength in a visible wavelength range extending from about 420 nm to about 680 nm, where n1>n2, and one of f1 and f2 is between about 0.55 and about 0.80. For illuminant D65 light incident on the multilayer optical film, the multilayer optical film reflects and transmits the incident light with the reflected and transmitted lights having color shifts below specified limits in a CIE L*a*b* color space. A glass laminate includes the multilayer optical film disposed between glass layers.
