Abstract
Two prismatic wedges of a prismatic compensator are rotated in opposite directions by the same angular quantity for adjusting the prismatic effect with the aid of a crossed-over pull wire. The pull wire is changed in direction by means of two rollers. The pull wire encloses the fittings under pulling tension so as to be free of slippage and free of play.
