Abstract
This paper describes the process by which Hughes Danbury Optical Systems successfully manufactured a beryllium secondary mirror for the NASA Jet Propulsion Laboratory's IR Telescope Technology Testbed. The secondary was fabricated and tested using conventional methods. Fiducialization was sued to calibrate and remove all systematic errors from the Hindle test. Additionally, surface roughness and scatter were fully characterized.
