Abstract

A simple method for interpreting Hartmann test data during the figuring process of a concave asphere is presented. The procedure is relatively fast and permits an estimation of the degree of smoothness and rotational symmetry of the mirror. It is not necessary to use all of the data point on the screen, but only those near one of it's radius. After the results from this test are satisfactory, the traditional, more complete and time consuming methods may be employed.
