1. An optical system, comprising:
an illumination device configured to generate illumination light comprising a light sheet;
a scanning device comprising a focal-length-variable illumination and detection optical unit having an optical axis, the scanning device being configured to generate a temporal sequence of at least two tilted illumination planes for illuminating a stationary sample volume, the at least two tilted illumination planes being tilted with respect to the optical axis and arranged at a distance from one another and parallel to one another; and
an erecting optical unit configured to image an image of the at least two tilted illumination planes in a planar manner in a detector plane.
