15 October 1993 COSTAR refractive aberration simulator alignment
Author Affiliations +
The Refractive Aberration Simulator (RAS) produces an image field which matches the as- built Hubble Space Telescope (HST) image field to a very high degree at 632.8 nm. The instrument is used to provide HST-like aberrated image plane illumination to the COSTAR and FOC-STM instruments during the final performance verification operations. It is capable of providing up to 15 simultaneous inputs to the instruments or metrology equipment located at its image plane. It consists of 6 anti-reflection coated glass lenses, each requiring lateral positioning accuracy as fine as +/- 10 microns, axial positioning accuracy of +/- 140 microns, and angular positioning of +/- 12.7 arcseconds, a fiber coupled laser source system, removable aperture stops for providing obscured or unobscured wavefronts, and a three-axis positionable source plate with removable fiber couplers for measurement or alignment operations.
