Figure verification of a precision ultra-lightweight mirror: Techniques and results from the SHARPI/PICTURE mirror at NASA/GSFC


A high-precision ultra-lightweight 0.5m mirror with ultraviolet grade tolerances on surface figure quality has been measured from its delivery to the Goddard Space Flight Center, through the coating and mounting process, and shown to survive component vibration testing. This 4.5kg, 0.5m paraboloid mirror is the prime optic of two sounding-rocket telescopes… (More)
