Abstract
CGH null testing of aspheric optics was first demonstrated by MacGovern and Wyant in 1971 but has only recently become available as a commercial product. This talk describes a variety of CGH null test configurations using both commercial and customized interferometers. Several of the aspheres and their associated CGH nulls will be shown to exhibit various pathological traits.
