Abstract: A polymer thin film includes polyethylene having a weight average molecular weight of at least approximately 500,000 g/mol, where the thin film is characterized by transparency within the visible spectrum of at least approximately 80%, bulk haze of less than approximately 5%, and an in-plane elastic modulus of at least approximately 10 GPa. The polymer thin film may be thermally conductive and may be incorporated into an optical element and configured to dissipate heat, such as from a light-emitting device.

Abstract: Eyeglass devices may include a frame shaped and sized to be worn by a user at least partially in front of the user's eyes, a varifocal optical element mounted to the frame, and an eye-tracking element mounted to the frame. The varifocal optical element may include a substantially transparent actuator positioned at least partially within an optical aperture of the varifocal optical element and configured to alter a shape of the varifocal optical element upon actuation. The eye-tracking element may be configured to track at least a gaze direction of the user's eyes, and the varifocal optical element may be configured to change, based on information from the eye-tracking element, in at least one optical property including a focal distance. Various other devices, systems, and methods are also disclosed.

Abstract: An optical element includes a waveguide body that is configured to guide light by total internal reflection from an input end to an output end, an input coupling element located at the input end for coupling light into the waveguide body, and an output coupling element located at the output end for coupling light out of the waveguide body, where the waveguide body includes an organic solid crystal. The organic solid crystal may be a single crystal having principal axes rotated with respect to the dimensions of the waveguide body. Such an optical element may have low weight and exhibit good color uniformity while providing polarization scrambling of the guided light.

Abstract: The disclosed apparatus may include a varifocal lens, where the transmissivity of the varifocal lens changes in relation to the optical power of the varifocal lens; and a transmissivity compensation component that is configured to change as the optical power of the varifocal lens changes, such that a variation of transmissivity of the varifocal lens is less than a variation of transmissivity of the varifocal lens in combination with the transmissivity compensation component. Various other apparatuses, systems, and methods are also disclosed.
