MICROSCOPE HAVING CORRECTION UNIT FOR CORRECTING A VARIABLE SPHERICAL ABERRATION

摘要

The invention relates to a microscope (21, 40, 60) having at least one correction unit (10), arranged in a beam path, for correcting a variable spherical aberration. The correction unit (10) comprises at least one optical correction element (12) that is moveably arranged along the optical axis (O) in a convergent or divergent region (14) of the beam path. The optical correction element (12) has a correction surface (18), the part of which that is passed through by the convergent or divergent region (14) of the beam path forming a correctionally effective surface section (20), the radial expansion of which can be altered across the optical axis (O) by moving the correction element (12) along the optical axis (O).
