Abstract

A microscope with at least one illumination beam that is phase modulated in a section along its cross-section with a modulation frequency and a microscope lens for focusing the illumination beam into a test as well as a detection beam path and at least one means of demodulation, wherein at least one polarization altering item is scheduled in the illuminating beam path, for which a phase plate is subordinated that exhibits at least two areas with different phase influence.
