Paper Abstract

The objective of the "Stressed Mirror Polishing" experiment is to investigate the practicality and economical feasibility of manufacturing precisely specified, large diameter, off-axis paraboloidal mirror segments, derived from a long radius of curvature parent paraboloid. Toward this end, the KPNO Large Optical Component Manufacturing Team is attempting to produce two nearly identical, 2-meter diameter segments, of 4.3-meter off-axis center distance, derived from a 40.5-meter radius of curvature parent paraboloid. Optical fabrication methods, optical alignment techniques, optical testing procedures, mechanical properties of the back support, and the bending fixture are discussed from the perspective of their use during manufacturing and testing.
