Paper Abstract

The principle of Offner's refractive null lens has been extended to test the transmission wavefront through conformal window optics and provide feedback during surface fabrication. First, the basic theory of the refractive null lens is reviewed followed by design examples for conformal optics. Second, given a specific window shape, the results and interpretation of a conformal widow test are described. Finally, a method of data analysis to reduce the transmission wavefront map to a more useful sag table is presented.
