PDF-Absolute Measurement of Rotationally Symmetrical Aspheric Surfaces Mic

Abstract The surface is scanned along its symmetry axis in a Fizeau cavity with spherical reference surface The coordinates xyz at the moving zone of normal incidence are derived from simultane.

In this paper, we will mainly explain one solution that Zygo has taken to measure aspheric surfaces, but also some alter-native approaches.
