Paper Abstract

The development of a null test configuration to measure the accuracy of an aspheric surface is presented. The surface form was measured using a refractive compensator lens in conjunction with a 170.52 transmission sphere to provide an interferogram representing the aspheric form deviation from the nominal. The interferometric data is compared to data obtained using a contact stylus profilometer. Keywords: null compensator, interferometric, oblate spheroid, aspheric
