Abstract
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.
Claims17
A microscope comprising:
- a main objective including a movable lens assembly, and
- an illuminating unit with an illumination deflector element for generating an illumination extending along an illuminating beam path directed onto an object plane and extending outside the main objective, wherein
- the movable lens assembly is movable along an optical axis of the main objective for setting various focal lengths of the main objective,
- the position of the illumination deflector element is adjustable for centering the illumination dependent on various focal lengths of the main objective,
- the illumination deflector element is arranged such that it is movable in parallel to the optical axis of the main objective, and
- the illumination deflector element is directly firmly and fixedly connected to the movable lens assembly of the main objective such that it is inevitably guided by the movable lens assembly and keeps the illumination beam path centered onto the object plane regardless of the position of the movable lens assembly.
