PATENTANSPRUCH:PATENT CLAIM: Objektiv für Photographic und Projektion, das zwei sammelnde und zwei zerstreuende Glieder, die von den sammelnden Gliedern umschlossen werden, enthält, wobei sämtliche acht Außenflächen der vier Glieder ihre hohlen Seiten dem von den Innengliedern begrenzten Blendenraum zuwenden und die den Blendenraum begrenzenden Flächen einen Scheitelabstand voneinander haben, der größer ist als vier Fünftel des arithmetischen Mittels aus den Krümmungsradien dieser Flächen, dadurch gekennzeichnet, daß jedes der beiden sammelnden Außenglieder aus mindestens zwei Linsen besteht, die eine voneinander verschiedene Farbenzerstreuung haben, derart, daß die Linse mit der geringeren Dispersion jedesmal die außenstehende ist und eine sammelnde Brechkraft hat, und daß jede der genannten, außenstehenden sammelnden Linsen einen größeren mittleren Brechungsindex hat als die ihr benachbarte zerstreuende Linse des Außengliedes.Lens for photographic and projection, the two collecting and two dispersing Limbs enclosed by the collecting limbs, containing all eight The outer surfaces of the four links have their hollow sides that are bounded by the inner links Turn the diaphragm space and the surfaces delimiting the diaphragm space a vertex distance of each other that is greater than four fifths of the arithmetic mean of the Radii of curvature of these surfaces, characterized in that each of the two collecting The outer links consist of at least two lenses that diffuse colors differently from one another in such a way that the lens with the lower dispersion always has the outer one is and has a collecting refractive power, and that each of the named, outsiders converging lenses have a larger average refractive index than their neighbors diffusing lens of the outer link.
