Paper Abstract

Testing of large aspheric concave optics to a surface quality of 1/50(lambda) rms or better requires knowledge of the test configuration error sources as the overall test configuration consists of a chain of test optics used to measure the actual optic figure. The intent of this paper is to discuss the testing and calibration techniques used on the Kodak segmented primary mirror with a reflective null compensator. Many of the calibration techniques discussed are applicable to a refractive test configuration (or for that matter, any optical test set).
