Paper Abstract

This paper describes the use of a Hartmann-type pupil mask and CCD camera to perform wavefront and focus validation of the Hubble Space Telescope simulator before and during environmental testing of the second-generation Wide Field and Planetary Camera. The method yields a focus accuracy at F/24 of about +/- 100 micrometers even in the presence of 3.5 waves of surface spherical aberration. The method avoids the introduction of potentially imperfect auxiliary optical tooling (e.g., null correctors).
