摘要：
The disclosure relates to an optical integrator configured to produce a plurality of secondary light sources in an illumination system of a microlithographic projection exposure apparatus. The disclosure also relates to a method of manufacturing an array of elongated microlenses for use in such an illumination system. Arrays of elongated microlenses are often contained in optical integrators or scattering plates of such illumination systems.
