The background and historical development at Corning Glass Works of lightweight mirror blanks are presented. Design considerations using a new low-expansion glass are given. The combination of the new material with near-zero thermal expansion and a fused monolithic core technology allows lightweight mirrors to be manufactured with weight savings approaching 80 percent of the equivalent solid and, at the same time, provides exceptional thermal and dimensional stability. Illustrations of lightweight mirror structures and core configurations are also presented.
