Abstract: 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.

Abstract: An optical well is configured to receive a test sample for examining an optical characteristic of the sample at a first wavelength in a predetermined wavelength range. The optical well includes a wall having a bottom wall portion and a sidewall portion defining a chamber for receiving the test sample, and an optical film formed into a shape so that a portion of the sidewall portion includes a first portion of the optical film, and a portion of the bottom wall portion includes a second portion of the optical film. For a normally incident light, the microlayers in each of the first and second portions have an average optical reflectance of greater than about 80% in the predetermined wavelength range. The forming results in the plurality of microlayers of the integral formed optical film having a thinnest portion and a thickest portion having a thickness difference of at least 30%.

Abstract: Multilayered polymer films are configured so that successive constituent layer packets can be delaminated in continuous sheet form from the remaining film. The films are compatible with known coextrusion manufacturing techniques, and can be made without adhesive layers between layer packets that are tailored to be individually peelable from the film. Instead, combinations of polymer compositions are used to allow non-adhesive polymer layers to be combined such that irreversible delamination of the film is likely to occur at interfaces between layer packet pairs. Some polymer layers, including at least one embedded layer, may include an ultraviolet (UV) light stabilizer such as a UV absorber, antioxidant, or hindered amine light stabilizer (HALS), and these layers may be positioned at the front of each layer packet. After the UV-stabilized layer of one packet has been used, the packet can be peeled away to expose a new UV-stabilized layer of the next layer packet.

Abstract: An optical system that allows a viewer to simultaneously see images created by an electronic display as well as real world objects includes a reflective polarizer as an image combiner for head-mounted displays and an absorptive polarizer deployed in the same combiner to reduce glare by minimizing ambient reflections from the reflective polarizer. To prevent the absorptive polarizer from blocking linearly polarized light sources from being transmitted through the combiner, a weak absorptive polarizer is provided to allow transmission of polarized sources while still minimizing glare.

Abstract: An optical system (200) that allows a viewer (10) to simultaneously see images created by an electronic display (20) as well as real world objects (30b) includes a reflective polarizer (41) as an image combiner for head-mounted displays and an absorptive polarizer (42) deployed in the same combiner to reduce glare by minimizing ambient reflections from the reflective polarizer. To prevent the absorptive polarizer (42) from blocking linearly polarized light sources from being transmitted through the combiner, a weak absorptive polarizer is provided to allow transmission of polarized sources while still minimizing glare.

Abstract: Multilayered polymer films are configured so that successive constituent layer packets can be delaminated in continuous sheet form from the remaining film. The films are compatible with known coextrusion manufacturing techniques, and can be made without adhesive layers between layer packets that are tailored to be individually peelable from the remainder of the film. Instead, combinations of polymer compositions are used to allow non-adhesive polymer layers to be combined such that irreversible delamination of the film is likely to occur at interfaces between layer packets pairs. Some of the polymer layers, including at least one embedded layer, comprise an antimicrobial agent, and these layers may be positioned at the front of each layer packet. After the antimicrobial layer of one layer packet has been used, the packet can be peeled away to expose a pristine antimicrobial layer of the next layer packet. The antimicrobial agent may be organic.
