1. A microscope for imaging a sample by a transmitted light contrasting method, the microscope comprising:
an objective lens holder or changer configured to place an objective lens of a number of objective lenses onto an optical axis of the microscope,
a lens system for forming an intermediate image of an exit pupil of any one of the number of objective lenses placed onto the optical axis, the intermediate image being formed at a respective conjugated plane conjugate to the exit pupil, and
a control device configured for automatically positioning a single modulation element for different objective lenses of the number of objective lenses onto the optical axis at a position related to the respective conjugated plane, and for automatically moving the modulation element in an axial direction parallel to the optical axis.
