Abstract

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.
