Abstract
A technique is described for measuring the absolute radius of curvature of spherical optical surfaces by using a calibrated gauge bar and interferometry. A description of test arrangements, experimental considerations, and results of a particular measurement are presented. Accuracies of the order of a few parts per million are practicable when the technique is used.
