Paper Abstract

Corning Incorporated has successfully completed the manufacture of three 8-meter class mirror blanks, the Subaru 8.3-meter and the twin Gemini 8.1-meter blanks. These mirrors, constructed of ULETM zero expansion glass by the hex seal process, are nearing completion at the optical polishers and will soon be installed in their respective telescopes. This paper describes the manufacturing process for the mirror blanks, summarizes key engineering studies performed during these projects, and gives quality results for the three blanks. In all cases, the 8-meter mirror blanks met both the customer's quality requirements as well as schedule timelines. Other applications of this process are also given.
