An Update on Progress in Ion Beam Figuring

Abstract

Results are presented from continuing research in Ion Beam Figuring (IBF). Theoretical aspects include a model of the ion beam figuring process for optics with a large amount of sag. Experimental aspects include results of aspherization of plane and f/1 spherical reflective optics. An update on the process characterization of various interesting materials (including silicon carbide) will also be presented.
