Abstract

Two types of monolithic lightweight mirrors with arched backs are discussed: the center-supported single arch and the ring-supported double arch. The theoretical deformations of a 20-in.-diameter double arch mirror are compared with the actual deformations. A mirror of this size weighs about 50% less than an equivalent conventional mirror. The double arch design may be scaled up to 144 in. where the mirror weighs less than 40% of the eauivalent conventional mirror. Further weight savings are possible due to the reduced size and simplicity of the support required by the double arch mirror design.
