Paper Abstract

This paper outlines recent progress in a novel active fabrication technique for severely aspheric optics. The underlying technology has been initially developed at the Optical Science Laboratory (OSL), at University College London, and has been incorporated in the OSL full-size active lap, used for polishing large astronomical optics. Optical Generics Limited (OGL) and OSL are currently collaborating to further develop the technology. A prototype OGLP-400 computer controlled polishing machine has been developed which exploits the technology for use with smaller aspheric optics up to 600mm diameter. The recent experimental results on both machines are presented, and their implications discussed.
