1. An optical arrangement for light beam shaping for a light microscope, comprising
a first liquid crystal region or lifting micromirror region with a plurality of independently adjustable liquid crystal elements or mirrors with which a phase of incident light is changeable in a settable manner;
a second liquid crystal region or lifting micromirror region with a plurality of independently adjustable liquid crystal elements or mirrors, with which a phase of incident light is changeable in a settable manner;
an input-/output-coupling polarization beam splitter to direct incident light of a specific polarization direction in a direction of the liquid crystal regions or lifting micromirror regions;
a polarization beam splitter, which is arranged between the input-/output-coupling polarization beam splitter and the liquid crystal regions or lifting micromirror regions such
that the polarization beam splitter separates the light coming from the input-/output-coupling polarization beam splitter, depending on a polarization, into a first partial beam, which is directed to the first liquid crystal region or lifting micromirror region, and into a second partial beam, which is directed to the second liquid crystal region or lifting micromirror region; and
that the polarization beam splitter combines the two partial beams returning from the liquid crystal regions or lifting micromirror regions and directs them together to the input-/output-coupling polarization beam splitter as an outgoing light beam.
