Abstract
A microscope comprising a main objective having a lens assembly movable in the direction of the optical axis of the main objective for focal length change and comprising an illuminating unit with illumination deflector elements for deflecting an illuminating beam path for generating an illuminating beam path directed onto an object plane. The position of the illumination deflector elements is adjustable dependent on a focal length change of the main objective for centering the illumination, and the illumination deflector elements are designed as at least partly integrated into the movable lens assembly of the main objective. For this purpose, in particular a part of the lens surface of the movable lens assembly can be made reflective.
Claims19
A microscope comprising:
- a main objective having a movable lens assembly;
- and
- an illuminating unit with illumination deflector means for deflecting an illuminating beam path in such a manner that an illuminating beam path is generated that is directed onto an object plane;
- wherein
- the movable lens assembly is movable in a direction of the optical axis of the main objective for a focal length change;
- the position of the illumination deflector means is adjustable for centering the illumination for various focal lengths of the main objective;
- at least a part of the illumination deflector means is integrated into the movable lens assembly of the main objective;
- and
- the part of the illumination deflector means integrated into the lens assembly of the main objective represents an at least partially reflecting lens surface of the movable lens assembly.
