Paper Abstract

A 2-meter diameter off-axis parabola has been produced using the stressed mirror polishing technique. Surface accuracy obtained was better than 0.25μm (rms), somewhat short of the intended goal. Further improvement is limited by mechanical factors. Results are presented. No further work is planned. Some of the equipment will be loaned to the fabricator of mirrors for the Keck Ten-Meter Telescope.
