Abstract

A microscope includes a light source(s) which produce an illumination beam path comprising light in a plurality of wavelength regions. A dichroic beam splitter arrangement having a dichroic mirror surface is arranged between objective optics and a tube lens in a beam path portion to produce a reflected partial beam and a transmitted partial beam. The beam splitter arrangement changes a propagation direction of the reflected partial beam relative to the illumination beam path by a specified deflection angle. The mirror surface is arranged at an angle of 22.5±7.5°. The beam splitter arrangement includes a further mirror(s) arranged in the reflected beam path. The propagation direction of the reflected partial beam is changed by the specified deflection angle using the sum of all reflections on the mirror surface and the further mirror(s).
