The blank would be l ft thick with a 2ft-diameter center hole, and ... , so that it maintained image quality. More than 40yr ago Corning had made the 200in blank for the Hale telescope out of borosilicate glass, having an expansion of 32.5 on a scale used by physicists; the material it would use for the space telescope blank would have an expansion of zero. Corning had chosen the new material, a titanium silicate ...
... .; the crack, extending radially more than 86 cm from the center hole, rendered the mirror blank useless. The original and replacement were cast from Cervit, a transparent ceramic material obtained by ... Space Telescope. When a different material was decided on for the Space Telescope, the Cervit blank was transferred to the infrared telescope project. Cervit had practically zero thermal expansion, making it ...

Manufacture of the mirror blank began in October 1977 at Corning Glass Works, which delivered it to Perkin-Elmer in December 1978.
