This paper will describe many recent aerospace applications where beryllium was successful used in different types of optical support structures. It discusses how several manufacturing methods, including machining, metallurgical brazing, epoxy bonding and near-net-shape processing were used to produce the desired overall configurations. The installation of non-beryllium inserts is also discussed in detail. Typically made of titanium, these inserts allow the end user to final finish mechanical attach points and optical lapping points, thus circumventing potential toxicity hazards associated with airborne beryllium particles. Data is also presented about stress and stability characteristics in some of the more specialized applications, as well as weight and stiffness.
