摘要： A molded glass lens is taught that includes a molded three-dimensional reference surface at a first end of the lens body, a first molded optical surface interrupting the three-dimensional reference surface, and a molded second optical surface at a second end of the lens body. The first and second optical surfaces may be plano, convex or concave. The molded three-dimensional reference surface is curvilinear and may be a spherical, aspherical or conical segment. The molded lens may include a second molded three-dimensional reference surface at the second end of the lens body. The molded three-dimensional reference surface is of a specified shape and location with respect to the first and second optical surfaces. By physically locating the lens with the molded three-dimensional reference surface and one of the first or second optical surfaces, the lens can be held in a given orientation. Thus, the molded reference surface(s) at the end(s) of the cylindrical body allow for accurate and safe capture, positioning, handling, and placement for subsequent finishing-operations, allowing for the creation of one or more additional lens datums.

摘要： Apparatus for coupling light from one optical fiber into another includes a pair of molded plano-convex lenses. Each lens has an aspheric surface and a flat surface. The aspheric surfaces have a conic constant between −0.6 and −0.3, where the conic constant is chosen so as to give optimal coupling efficiency from a collimated beam input on the aspheric surface into an optical fiber located near the flat surface. The pair of lenses are separated by a distance approximately equal to the sum of the focal lengths of the lenses. Light from an optical fiber placed near the focal plane of one of the pair of lenses is focused into an optical fiber placed near the focal plane of the other of the pair of lenses.

摘要： A molded glass lens is taught that includes a molded two-dimensional reference surface at a first end of the lens body, a first molded optical surface that is longitudinally displaced from the two-dimensional reference surface, and a molded second optical surface at a second end of the lens body. The first and second optical surfaces may be plano, convex or concave. The molded two-dimensional reference surface is planar and preferable annular. By physically locating the lens with the molded two-dimensional reference surface and one of the first or second optical surfaces, the lens can be held in a given orientation. Thus, the molded reference surface at the end of the cylindrical body allows for accurate and safe capture, positioning, handling, and placement for subsequent finishing operations, allowing for the creation of one or more additional lens datums.

摘要： A method and apparatus is disclosed for compression molding arrays optical elements which may be later singulated. The apparatus includes first and second mold halves with the second mold half having a central nest and a plurality of predetermined negative optical surface features therein. A glass preform is placed in the central nest and the first and second mold halves and the glass preform are heated to at least the glass transition temperature of the glass preform. The glass preform is then pressed between the first and second mold halves to thereby form an integral array of optical elements with each of the optical elements being a positive of the predetermined negative optical surface features. The integrally formed array of optical elements is then cooled to below the glass transition temperature and removed from the first and second mold halves.
