Paper Abstract

The stressed mirror polishing method is being used to produce two thin two-meter diameter off-axis parabola mirrors. These mirrors are prototypes for a large segmented mirror telescope and the initial objective is to achieve 0.025 micron (RMS) surface accuracy. The fabrication set-up will be described along with improvement modifications that have proven to be necessary. Polishing results to date will be presented.
