Abstract

Three f/2 paraboloids, 12 inches in diameter, were given short final polishing runs using colloidal silica and full-sized flexible laps. No degradation of surface figure was detected, and we obtained a reduction in surface scatter to levels indicating a surface microfinish of 15 A rms or less.
