The true potential of replicative molding processes is in the expansion of geometrical complexity. This is where the crucial economic advantage in replicating a costly shape a hundred or a thousand times takes effect. For this reason, precision molding has found its main application in the area of high-precision aspherical optics. Aspherical optics are frequently used in optical systems nowadays and usually aim at eliminating imaging errors ? a task that must otherwise be accomplished using multiple-lens correction systems. The aspherical insert thus reduces weight and volume, and is therefore very desirable for mobile applications (e.g. cameras and cell phones).
