Paper Abstract

Design characteristics which influence the cost and producibility of near-net-shape blanks for light-weight beryllium optics discussed. Producibility factors include cell geometry and mountings. Design rules are presented for defining the size, shape and arrangement of light-weighting cells. Particular emphasis is given to the size of web intersections. The use of internal versus external mountings is evaluated with respect to cost and producibility. Overall optic cost is reviewed with respect to the impact of blank fabrication requirements on the optic design, the design and fabrication of tooling, and the fabrication of the optic blank. Standards are proposed for specific mirror blank characteristics. These standards are presented as a starting point for discussion.
