摘要： A negative lens, for an oblique-view endoscope objective, has a first face with a first optical surface and a second face with a second optical surface opposing the first optical surface, the second optical surface being a concave optical surface, wherein a recess is formed in the second face adjacent to the concave optical surface. An endoscope objective, that includes a deflection prism having an entrance face and further including a negative lens, the negative lens having a first face with a first optical surface and a second face with a second optical surface opposing the first optical surface, the second optical surface being a concave optical surface. The negative lens is mounted on a distal planar surface of the deflection prism such that a rim encompassing the concave optical surface abuts the distal planar surface of the deflection prism.

摘要： In an optics tube for an endoscope, a lens arrangement including at least one rod lens is received in the inside of the optics tube, wherein a sleeve is fixed on the at least one rod lens and at least partially encloses the rod lens, and wherein the sleeve is welded to the optics tube. The invention also relates to an endoscope having such an optics tube, and to a method for mounting at least one rod lens in the inside of an optics tube.

摘要： A relay lens system for transmitting an image from a distal end of the relay lens systems to a proximal end of the relay lens system including a plurality of imaging devices with in each case one or more lenses, wherein each imaging device of the plurality of imaging devices images a real intermediate image distal to the imaging device into a further real intermediate image proximal to the imaging device. The plurality of imaging devices has a plurality of first imaging devices and a second imaging device. The first imaging devices each have a chromatic aberration. The chromatic aberration of the first imaging devices is corrected by the second imaging device. The second imaging device is arranged between the first imaging devices.
