This paper describes the structural design, analysis, and load/deflection tests of a generic all- beryllium telescope truss (metering structure). The assembly serves to verify the viability of building lightweight precision mirrors and structures for high performance space-based optics and to measure the integrated performance of state-of-the-art CCD focal planes. It demonstrates the feasibility of manufacturing lightweight and stiff structures that can support high performance optical systems and meet their alignment requirements. The goal of building a telescope worthy of space flight was met.
