Paper Abstract

Many aspherics can be tested using straightforward and simple methods that yield non-complex fringe patterns. The methods described are essentially null tests similar to those utilized for measuring large mirrors for astronomical work. The potential for such a test to exist for a given aspheric should always be explored prior to using more complicated and more costly techniques. This paper describes some of the analytical methods that are used to tackle the problem of determining which test may be used as well as the limitations of this approach. Experimental results are also presented.
