英文摘要	A coupling element for an optical transmission system, in which the coupling element comprises a convex lens having a refractive index which is dependent on the radius r of a shell in the lens, and a holder. Use is preferably made of lenses having a refractive index N(r)=N1x(2-(R/Ro)2)1/2, where N1 is the refractive index of the core of an optical fiber (approximately 55) and Ro is the radius of the lens. The coupling of monomode fibers via lenses of this kind can be effected wth large dimensional tolerances.
