Paper Abstract

This paper addresses technology advances in the replication of Be optics to optical figure requirements. The replication effort discussed has achieved a specific net, aspheric optical figure within several waves (6328 A) peak-to-valley, combined with replication cross sections and features as thin as 0.020 inch, to tolerances of less than 0.005 inch. The replication is performed in a HIP consolidation process. Currently, the process has been applied to fabrication of developmental quantities of nonimaging, small optical components including plano, spherical and aspheric configurations. The process discussed is applicable to cost-effective high volume production of small Be optical and nonoptical components, and the principles employed may be effective in reducing costs for large Be optics in low volumes.
