  • Patent number: 11002978
    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).

  • Patent number: 10948731
    Abstract: A diffractive optical element (DOE) is designed to implement both a collimation function with respect to an input divergent beam and a beam shaping function with respect to an output divergent beam. The phase designs of the collimation function and the beam shaping function are independently produced in the phase domain. These phase designs are then combined using a phase angle addition of the individual functions and wrapped between 0 and 2? radians. The diffractive surface of the DOE is then defined from the wrapped phase angle addition of the individual functions.
