A method for manufacturing thin, multi-bend optics includes placing an optical substrate and a protective sheet into a compression mold and closing the compression mold to deform the optical substrate and to deform the protective sheet. The optical substrate can include an optical surface and the protective sheet can be disposed between the compression mold and the optical surface of the optical substrate. The compression mold can include a mold contact surface that is characterized by a surface roughness. The compression mold can be held in a closed position for a compression time period, during which, the protective sheet contacts the mold contact surface and provides a buffer layer between the mold contact surface and the optical surface thereby mitigating against transfer of the surface roughness of the mold contact surface onto the optical surface.

The present disclosure provides a production method for a Luneburg lens, which can manufacture a Luneburg lens with stable indexes and high performance under the conditions of room temperature, normal pressure, and low cost. The production method includes the following steps: bonding first granular materials into a sphere by a bonding agent, so as to obtain a sphere core; spraying the bonding agent on the surface of the sphere core, placing the sphere core in a container containing second granular materials, and rolling the sphere core, so that the surface of the whole sphere core is bonded with the second granular materials until the thickness of the second granular particles reaches a preset range, and thus forming a dielectric layer coating the sphere core; and by analogy, preparing a predetermined number of dielectric layers, so as to obtain a target finished Luneburg lens.

A method of manufacturing an optical multiplexer, whereby one molded product is formed by using a mold and vertically cut in a row direction, thus efficiently manufacturing multiple optical multiplexers, with a microlens array and an optical block being integrated together. Therefore, the present invention may increase product productivity and realize a size reduction of a product.

A mold for a front curve of an ophthalmic lens includes an inner region having a non-rotationally symmetric shape, an outer region having a rotationally symmetric shape, and a continuous middle region between the inner region and the outer region. A first portion of the middle region is in contact with the inner region, defining a non-rotationally symmetric rim or edge of a front surface of the ophthalmic lens. A second portion of the middle region is in contact with the outer region and is rotationally symmetrical.

The present invention relates to a method for manufacturing an aspherical optical member. Compared with conventional cutting-type or drawing-type optical member manufacturing technology, the present invention can mass-produce an aspherical optical member at a low cost by using a simple stacking method, and can manufacture the aspherical optical member without changing a conventional process line.
