Paper Abstract

Refractive or diffractive microlenses have already been reported. Here we discuss two examples of microlenses where the generation process and the interferometric control are strongly interwoven. For refractive lenses we use lenses melted in photoresist and also reactive ion etched samples. The control is done with the help of a phase shifting interference microscope of the Mach-Zehnder type. We developed an evaluation software under Windows. The software allows for the evaluation of the wave aberrations and related functions as are psf and otf.
