Optical Materials: Double-Sided Lapping and Polishing

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.
