Abstract

Corning Incorporated has had success with many of the large optics for different programs. Corning's ability to fuse ULE^® monolithic blanks from smaller portions allows for a wide variety of shapes and configurations. Corning's latest success has come with the Discovery Channel Telescope (DCT) 4.3 meter ULE^® blank, produced for Lowell Observatory. This paper will document the process for the fabrication of the blank from inception to completion and shipment of the blank to the customer. There will be discussion of the manufacturing processes, ULE^® selection, and handling.
