Abstract

A surgical microscope, in particular an ophthalmic surgical microscope, includes a microscope imaging optical unit for imaging an object to be observed in an image plane along an optical imaging beam path, which passes through the microscope imaging optical unit, and a camera, which captures imaging of the object in the image plane. Further, the surgical microscope includes an optical wavefront encoding element that is positioned or positionable in the optical imaging beam path to influence an imaging light wavefront in the optical imaging beam path in such a way that a depth of field of the imaging of the object through the microscope imaging optical unit with the wavefront encoding element is reduced in relation to the depth of field of the imaging of the object through the microscope imaging optical unit without the wavefront encoding element.
