Abstract
A 3.5-meter-diameter telescope primary-mirror blank was cast from E6 borosilicate glass at the University of Arizona, Steward Observatory Mirror Lab. A light-weighted-hollow design was made with a faceplate and backplate separated by a middle volume of ribs in a honeycomb pattern. The curvature of the F/l.75-mirror face was formed by spinning the melted glass at 8.54 RPM. A telescope on Apache Point in New Mexico will use this mirror.
