A Rogues’ Gallery of CGH Null Tests

Steven Arnold

Open Access Open Access

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.
