Microscope with centered illumination

摘要

A microscope comprising a main objective including a lens assembly movable in the direction of the optical axis of the main objective for focal length variation and comprising an illuminating unit with an illumination deflector element for generating an illuminating beam path directed onto an object plane and extending outside the main objective. The position of the illumination deflector element is adjustable dependent on a focal length variation of the main objective for centering the illumination. The illumination deflector element is movable in a direction parallel to the optical axis of the main objective and is coupled to the movable lens assembly of the main objective.
