Abstract

The lessons learned in recent fabrication of beryllium mirrors could have a significant impact on how beryllium optics of the future are produced. This paper provides an overview of the latest techniques for beryllium optics fabrication and a comparison of the results achieved. Specific technical ureas discussed include: new beryllium powders, results of consolidation, beryllium material property improvements, modified machining procedures, thermal stabilization, single point turning, burnishing techniques, replica faceplates, support structure bonding, mirror superpolishing, and new optical testing techniques.
