Abstract: In some examples, a method may include injection molding an optical material in a mold defining at least one optical surface to form a molded component, and machining the molded component to form a machined optical component including a machined optical surface. In some examples, a method may include injection molding an optical material in an axially symmetric mold cavity defining at least one optical surface to form a molded component, and machining the molded component to form an optical component that does not possess axial symmetry. Optical component formed by these methods and molds for utilizing in these methods also are described.
