Grazing incidence interferometry for testing rough aspherics (JTh5A.93)

Presenter: Sergej Rothau, Institute of Optics, Information, and Photonics

Here, we demonstrate the theory, the setup and the results of a grazing incidence interferometer using visible light in combination with phase shifting techniques for the surface measurement of convex steep rotational symmetric and rough aspherics.
