Measurement result of an asphere.

Caption

Measurement result of an aspheric shaped specimen measured with the novel Tilted Wave Fizeau Interferometer. The deviation from the nominal design surface shape is shown. The specimen shows three markers at the lower rim of the surface. These are three Gaussian shaped dips that nicely illustrate the high lateral and height resolution of the method.
