Abstract

A light-weighted optical assembly is provided. The light-weighted optical assembly of the invention is comprised of two members. Each member is constructed of a section and a plurality of ribs extending from the section and comprises one-half of the total thickness of the optical assembly. The members are fused at second ends of the plurality of ribs in a crossing, abutting manner. It is the crossing, abutting fusion of the two members which maintains the rigidity and stiffness of the optical assembly so as to insure against deflection of any reflective surface.
