Abstract
A novel method for assessing a surface figure of an optical element. The method preferably comprises subjecting the optical element to a classical autocollimation testing procedure for ascertaining its surface figure relative to a predetermined ideal. The testing procedure is characterized by a step of modifying the classical optical testing procedure, so that the optical element under test simulates a paraboloid.
