Paper Abstract

Fabrication of lightweight mirrors from low expansion glass can be achieved using various core and faceplate lightweighting techniques. Lightweighting can be achieved using abrasive waterjet (AWJ) cutting, CNC machining and a new approach that Corning is developing to produce lightweight cores based on Corning's patented extrusion process. The selection of which lightweighting technology to use is dependent on customer design considerations of the lightweight mirror. These lightweighting techniques are reviewed and discussed, along with advantages and disadvantages of each technique. Corning will also introduce and discuss its new extruded core lightweighting process.
