摘要: A unitary multi-optic system for a vehicle having two or more co-molded individual optics molded from optical silicone such that each individual optic is adjacent at least one other individual optic, each individual optic configured to be illuminated with a respective radiation source. An optical-blocking barrier is integrally molded with the individual optics and configured to interfere with transmission of undesired source emissions between the two or more co-molded individual optics. The two or more co-molded individual optics are headlamps or tail lamps of the vehicle.

摘要: The invention relates to an optical microlens array and to a method for manufacturing an optical microlens arrays, wherein the method includes, among other things: providing a substrate having a first side and an opposite second side. The method further includes applying a photoresist to the first side of the substrate at least in portions, and structuring the photoresist such that the structured photoresist remains at predetermined locations on the first side of the substrate where one optical microlens each is to be later arranged. In addition, the method includes applying a hydrophobic coating to the first side of the substrate and subsequently removing the structured photoresist including the hydrophobic coating located thereon from the first side of the substrate. Furthermore, according to the invention, one microlens each is arranged on the spots of the first side of the substrate that are freed from the structured photoresist.

摘要: A technology with a simpler and smaller configuration and capable of suppressing light leakage from an optical module is provided. An optical device (3) includes an optical region (3a) in which an optical element is arranged, at a part of at least one surface of a substrate portion (3b) having a flat plate shape. A peripheral region (3d) in which an optical function as an optical device is not used is provided around the optical region (3a) at the surface, of the substrate portion (3b), provided with the optical region (3a). A light-blocking and diffusing portion (3e) configured to suppress transmission of light or diffuse light is formed at the peripheral region (3d) or a region corresponding to the peripheral region (3d) at an opposite surface of the substrate portion (3b).

摘要: Techniques for controlling the flow of replication material (e.g., epoxy) during the formation of replicated optical elements include providing a transparent substrate (220) onto which the optical elements are to be replicated. The substrate (220) includes a structured UV curable shield (202) adhering to its surface. The UV curable shield (202), in turn, has openings (203) that expose portions of the surface of the transparent substrate (220) for replication of the optical elements. During the replication process, excess replication material (124A) may flow onto the UV curable shield (202), which subsequently can be cured so as to facilitate the release and removal of the shield (202) along with the excess replication material (124A).

摘要: An optical lens assembly is produced by an injection-compression molding process. The optical lens assembly includes a lens body and an injection-molded structure. The lens body includes a first lens surface and a second lens surface opposed to the first lens surface. The lens body is divided into an optically effective zone and an optically ineffective zone. The injection-molded structure has at least one gate land in response to the injection-compression molding process. At least a portion of the optically ineffective zone of the lens body is covered by the injection-molded structure, and the injection-molded structure is assembled with and positioned by an external structure. Each of the first lens surface and the second lens surface is one of a multi-aperture lens surface, a lenticular lens surface, an aspheric lens surface, a flat lens surface and a freeform lens surface.
