Abstract

This paper reports on current manufacturing and polishing characteristics of sputtered and optical-grade bare beryllium. The Ball Aerospace and Technologies Corp. has evaluated flight optics and samples which have determined some of the current characteristics and capabilities of these beryllium materials. The capability of some optical component manufacturing companies to produce optics from bare, sputtered, and electroless nickel-plated beryllium has also been evaluated. A variety of optics and test samples were made, including polished bare beryllium, beryllium-sputtered, and electroless nickel-plated beryllium components. Two types of sputtered beryllium were evaluated, and several component manufacturing houses were used to polish the sputtered beryllium. The results from new technologies for polishing bare beryllium have been assessed.

The paper will provide a general overview of success and limitations of the manufacturing, polishing, and figuring of the above materials. The current status of spherical powder beryllium will also be discussed. The manufacturing techniques for creating high quality bare beryllium, sputtered beryllium and electroless nickel-plated beryllium optics will be presented. New testing methods for evaluating a test sample will also be discussed.
