Paper Abstract

The construction of very large optical telescopes can be prohibitively expensive due to the massive size and weight of the required primary mirrors. One method of reducing the cost of such telescopes is the use of a segmented primary mirror. The computer controlled polisher (CCP) approach is ideally suited to the fabrication of telescope mirror segments. Since the process achieves controlled material removal by regulating the tool motion, there is no need for any surface symetry. Recent experiments have demonstrated the ability of the CCP to figure mirror segments.
