Abstract

Off axis parabolas (OAPs) allow for more confined and intricate optical system designs, but meeting tight irregularity and slope specifications can be difficult due to distortion in null test setups. This distortion is exacerbated with steeper off axis angles (OAA). This paper will show different methods to correct distortion in an autocollimation measurement of an OAP, and how to determine when to use each method.
