摘要： A mirror system for a side- or rear-view mirror of a vehicle includes a light absorbing layer and an optical film having a plurality of layers disposed on the light absorbing layer. For substantially normally incident light and a blue, green, and red wavelength range extending from about 420-485 nm, 525-575 nm and 625-740 nm, respectively, and for at least one polarization state, the plurality of layers includes a reflection band having a substantially flat top region at least 100 nm wide. The reflection band includes left and right band edges at respective short and long wavelength sides. The plurality of layers has an average optical reflectance R1 of greater than about 70% and a standard of deviation of less than about 5% in the substantially flat top region. An average optical reflectance Rb is less than about 0.8R1 in the blue wavelength range.

摘要： Embodiments of the present disclosure relate to a multi-layer film and display system. The multi-layer film and display system includes a birefringent film, wherein the birefringent film substantially reduces a visibility of a regular optical pattern generated on the multi-layer film and display system when an at least partially polarized light is incident on the multi-layer film and display system.

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 heads-up display includes a windshield (10) with a standardized wedge profile and an embedded reflective polarizer (20) for p-polarised light and a display (40). The reflective polarizer is disposed between, and spaced apart from, opposing outermost first and second major glass surfaces (11, 12) of the windshield. The heads-up display forms a virtual image for viewing by the eye of a passenger. An image emitted by the display may include a first image ray emitted from a predetermined region of the display and incident on the outermost first major glass surface of the windshield at an angle of incidence greater than about 60 degrees, with at least 90% of the incident first emitted image ray polarized in a plane of incidence of the first emitted image ray.

摘要： An optical film includes a plurality of alternating first and second polymeric layers, such that the first polymeric layers have a smaller average in-plane index of refraction than the second polymeric layers and the first polymeric layers have a glass transition temperature of at least 107 deg. C. The optical film may be a reflective polarizer. An optical stack includes a linear absorbing polarizer and the reflective polarizer disposed on, and bonded to, the absorbing polarizer. The reflective polarizer has an optical reflectance of at least 60% for a first polarization state and an optical transmittance of at least 60% for an orthogonal second polarization state. When heated at 105 deg. C. for 15 minutes, a difference in shrinkage of the reflective polarizer and the absorbing polarizer along the first and second polarization states is greater than about zero and 0.2%, respectively.

摘要： Multi-layer films, and processes to make the films, that enable the delivery of a substrate featuring a peelable thin layer of low haze, amorphous, isotropic film with the desired properties of high modulus, high usage temperature, UV blockage, and toughness The films are made using a co-extrusion, co-orientation and annealing process to enable the delivery of a thin isotropic, UV blocking layer on top of a release layer and support substrate. These film constructions can be kept together during additional processing steps such as coating and converting. The release and dimensionally stable substrate layer can be easily removed once processing steps are completed.
