Optical Materials: DoubleSided Lapping and Polishing
With doublesided 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. They are processed between an upper and lower plate that, depending on machine design, can rotate either in the same direction or opposite directions, or remain
