Abstract

A microscope including an optical unit and a collimator. The collimator is arranged preceding or following the optical unit in a beam path of the optical system. The optical unit imposes a predetermined longitudinal chromatic aberration on a beam supplied to a beam path and the beam impinges on the collimator as a diverging beam or a parallel beam and is converted by the collimator into a parallel beam or a converging beam. The collimator includes at least one lens as well as a curved mirror which folds the beam path such that the supplied beam passes twice through the lens.
