Abstract: An example apparatus may include a display and an optical configuration configured to provide an image of a display, for example, in a head-mounted device. The optical configuration may include a Fresnel lens assembly including a Fresnel lens and a reflective polarizer. The Fresnel lens may have a structured surface including a plurality of facets, and there may be a step between pairs of neighboring facets. The reflective polarizer may include a plurality of reflective polarizer portions, where each reflective polarizer portion conforms to a corresponding facet of the Fresnel lens. The reflective polarizer may be configured to reflect a first polarization and transmit a second polarization of incident light. The optical configuration may form an image of the display viewable by a user when the user wears the apparatus. Other devices, methods, systems, and computer-readable media are also disclosed.

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: The disclosed computer-implemented method may include coupling an array of reflective polarizers to a back surface of a back optical substrate; coupling an array of quarter-wave plates to a front surface of the back optical substrate such that the array of quarter-wave plates is aligned with the array of reflective polarizers; molding the back optical substrate with at least one initial mold, wherein the at least one initial mold defines an initial array of optical element surfaces that is aligned with the array of quarter-wave plates; and twin-sheet thermoforming, between a front twin-sheet mold and a back twin-sheet mold, the back optical substrate with a front optical substrate, wherein the front twin-sheet mold defines a front array of optical element surfaces and the back mold defines a back array of optical element surfaces. Various other methods, apparatuses, and systems are also disclosed.
