摘要: Various embodiments are disclosed herein that relate to the molding of an item having a non-uniform thickness and an undercut structure. One disclosed embodiment provides an injection molding device for molding a part having a non-uniform thickness and an undercut structure, the injection molding device comprising a pair of opposing end walls, a first mold surface being stationary with respect to the pair of opposing end walls, and a second mold surface being movable toward the first mold surface such that a first end of the second mold surface is movable a larger travel distance toward the first mold surface than a second end during a molding process. Further, the pair of opposing end walls comprises a slider with an undercut mold surface that is movable in a direction transverse to a direction in which the second mold surface is movable toward the first mold surface.

摘要: Various embodiments are disclosed relating to fabrication of an optical wedge. For example, one embodiment provides a method for manufacturing an optical wedge comprising inserting a wedge blank into a vacuum molding tool and applying a vacuum to the vacuum molding tool to temporarily hold the wedge blank against a molding surface of the vacuum molding tool. The method further comprises removing a layer from a top surface of the wedge blank to expose a machined surface of the wedge blank, and casting a finish layer on the machined surface to form a finish layer of a finished optical wedge.

摘要: Embodiments are disclosed that relate to fabrication of a laminated optical wedge. One embodiment provides a method comprising inserting a wedge blank into a vacuum molding tool, applying a vacuum to the vacuum molding tool, and removing a layer from a top surface of the wedge blank to expose a machined surface of the wedge blank. The method further comprises laminating a finish piece to the machined surface via an adhesive, wherein the finish piece comprises a smoother surface than the machined surface, and curing the adhesive to form a finished optical wedge. The method further comprises removing the finished optical wedge from the vacuum molding tool.

摘要: Embodiments of optical collimators are disclosed. For example, one disclosed embodiment comprises an optical waveguide having a first end, a second end opposing the first end, a viewing surface extending at least partially between the first end and the second end, and a back surface opposing the viewing surface. The viewing surface comprises a first critical angle of internal reflection, and the back surface is configured to be reflective at the first critical angle of internal reflection. Further, a collimating end reflector comprising a faceted lens structure having a plurality of facets is disposed at the second end of the optical waveguide.

The viewing surface comprises a first critical angle of internal reflection, and the back surface is configured to be reflective at the first critical angle of internal reflection. Further, an end reflector is disposed at the second end of the optical waveguide, and includes a faceted lens structure to cause a majority of the viewing surface to be uniformly illuminated when uniform light is injected into the first end and also to cause a majority of the injected light to exit the viewing surface.
