Real bodies emitting electromagnetic radiation in JR spectral re- gions are imaged by infrared optical systems on detectors. An important point is to design these systems so that they work in a wide ternperature range without refocussing. Athermic lenses fulfilling this requirement are realized by specific correction measures. On this basis a complete series of lenses for the short-focal-length range has been developed.
