A precision mirror fiducializinq system for use in large optics fabrication has been developed and demonstrated. The arrangement is compatible with Perkin-Elmer's Computer Controlled Polishing (CCP) facility and Coaxial Reference Interferometer (CORI). The absolute position of figure errors on the mirror surface can be determined through measurements on the interferogram to within lmm on mirrors in the 1-2 meter diameter range.
