Abstract
In order to measure geometrical errors of the fabrication process of cylindrical lenses, a grazing incidence interferometer is used to test 4 surfaces of the lenses. Two specially designed diffractive optical elements are working as beam splitter, recombiner as well as reference for the ideal lens shape and ideal centration of the surfaces relative to each other.
