machine, and there, in a correction phase, reduced by further polishing to an acceptable minimum. Figure 1: Comparison between a spherical and an aspherical surface In the diagram above, the outline of an aspherical profile is traced in comparison with spherical form present in the middle of the lens.
In theory, the process requires a minimum of three parts. The actual number is determined by part quantity, part size, and machine size. With double-sided lapping and polishing (DSLP), the optical components are held in geared or sprocketed carriers that are driven in a planetary motion covering the full surface of the lapping plates and are subject to continually changing direction of rotation.
