Claim 11:
12. A method for light beam shaping for a light microscope, comprising
phase-modulating light by means of a liquid crystal matrix or lifting micromirror matrix, which has a plurality of independently switchable liquid crystal elements or mirrors;
guiding light of a specific polarization direction by means of an input-/output-coupling polarization beam splitter;
splitting the light coming from the input-/output-coupling polarization beam splitter in a polarization-dependent manner into a first partial beam and into a second partial beam by means of a polarization beam splitter;
wherein the phase modulation of light by means of a liquid crystal matrix or lifting micromirror matrix comprises:
directing the first partial beam to a first liquid crystal region or lifting micromirror region of the liquid crystal matrix or lifting micromirror matrix; and
directing the second partial beam to a second liquid crystal region or lifting micromirror region; and

combining the two partial beams returning from the liquid crystal regions or lifting micromirror regions by means of the polarization beam splitter; and
directing the combined partial beams as an outgoing light beam to the input-/output-coupling polarization beam splitter.
