摘要： An endoscope having an elongate shaft, an objective arranged in a distal end region of the shaft for generating an image of an object field in an image plane. The objective having a beam splitter, and an image recorder for recording the image of the object field and an optical waveguide for forwarding illumination radiation from a proximal region to the distal end region of the shaft. The endoscope being embodied as a contact endoscope, a sensor area of the image recorder arranged in the image plane and an emergence portion of the optical waveguide adapted to forward at least some of the illumination radiation to the beam splitter to illuminate the object field.

摘要： An illumination arrangement according to the invention, in particular for an endoscope, comprises at least three light sources for generating a respective input light beam, and a beam combination device (5, 21), wherein the beam combination device (5, 21) comprises at least two beam splitters for combining the at least three input light beams to form an output light beam, at least three collimator lenses (7, 8, 9) embodied as GRIN lenses and serving for collimating and coupling a respective one of the input light beams into one of the beam splitters, and at least one further GRIN lens for coupling the output light beam into an optical waveguide. The invention also relates to a beam combination device and a method for coupling at least three input light beams into an optical waveguide, in particular into an optical waveguide of an endoscope.
