Paper Abstract

The weight and line of sight (LOS) stability are very critical in telescopes used for remote sensing and imaging in the presence of high dynamic loads and vibrations. A high stiffness and low-density material such as beryllium is ideally suited for such applications in spite of its high cost. This paper presents the design of an all-beryllium off-axis telescope in which the three diamond-machined mirrors are pinned and bolted to an extremely lightweight and stiff support structure. A number of design and fabrication techniques were employed to minimize the cost of material and fabrication. The importance of machining tolerances for optimizing the cost and yield of mirrors is also described.
