22 October 1985Bend-And-Polish Fabrication Techniques
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) or within about 1% of the intended goal. Further improvement is limited by mechanical factors. Results are presented. No further work is planned.
