ABSTRACT:
An endoscope has an endoscope tube and a lens system arranged in the endoscope tube. The lens system has endoscope lens components and air gaps between the lens components. An illumination system is arranged within the endoscope tube. The endoscope lens components each have an axial lens length; the endoscope lens components include first lens components and second lens components, wherein the axial lens length of the first lens components is the shortest axial lens length, respectively, and wherein the axial lens length of the second lens components is longer than the shortest axial lens length. The first lens components with the shortest axial lens length are arranged in an area of an axial center of the endoscope tube. The second lens components having the longer axial lens length have a first half and a second half and an air gap arranged between the first and second halves.
