Abstract: What is described here is a relay lens system, specifically for endoscopes or the like, comprising two rod-type lens elements and two further optical elements in symmetrical arrangement relative to the center plane of the object plane and the image plane.The relay lens system according to the present invention is characterized by the fact that the rod-type lens elements are individual convex/concave optical elements and the further elements are individual bi-convex optical elements, and that one rod-type lens and one further lens, respectively, are bonded to each other.This structure according to the present invention contributes to an enhanced compensation, specifically of the field curvature and astigmatism, while furnishing a brighter image.
