Abstract: A multilayer polymer thin film includes an anti-reflective coating directly overlying a reflective polarizer stack. The reflective polarizer stack includes alternating first and second polymer layers, where the first layers include an isotropic polymer thin film and the second layers include an anisotropic polymer thin film. The anti-reflective coating (ARC) includes alternating third and fourth layers, where the third layers include an isotropic polymer thin film or an anisotropic polymer thin film and the fourth layers include an isotropic polymer thin film. The multilayer polymer thin film may be formed by co-extrusion where the reflective polarizer stack and the anti-reflective coating are formed simultaneously.

Abstract: A polymer multilayer includes two or more laminated layers of ultra-drawn, ultra-high molecular weight polyethylene or high density polyethylene. A transparent laminated structure may include such a polymer multilayer disposed between a pair of transparent substrates. The polymer multilayer may be configured to induce a compressive stress in a near surface region of each transparent substrate, which may improve the toughness and fracture resistance of the laminated structure. A photothermal dye may be incorporated into the polymer matrix and the compressive stresses may be achieved using photothermal actuation of the dye-containing polyethylene layers.

Abstract: A hybrid lens includes a primary lens element having a pair of opposing optical surfaces and a secondary lens element disposed directly over at least one of the optical surfaces. The primary lens element may include a 3D-printed layer, and the secondary lens element may be over-formed by casting. An electronic component such as a dimming component, a waveguide component, or an eye-tracking component may be integrated into the hybrid lens.

Abstract: A method of manufacturing a meniscus lens includes providing an optical lens substrate having a non-planar deposition surface and depositing a resinous layer over the deposition surface to form the lens. Such a printed lens may have a radius of curvature of less than approximately 80 mm, sag of from approximately 2 mm to approximately 20 mm, a maximum thickness of less than approximately 40 mm, and a minimum thickness variation of at least approximately 2 mm.

Abstract: A polymer thin film includes polyethylene having a molecular weight of at least approximately 250,000 g/mol, and has an elastic modulus of at least approximately 25 GPa, a tensile strength of at least approximately 0.8 GPa, and a thermal conductivity of at least approximately 5 W/mK. Formation of the polymer thin film may include forming a polymer solution from a crystallizable polyethylene and a liquid solvent, forming a gel from the polymer solution, forming a polymer thin film from the gel by calendering or solid state extrusion, and stretching the polymer thin film.
