Description

Photographisches Objektiv Die Erfindung bezieht sich auf ein photographisches Objektiv aus vier in Luft stehenden Gliedern, bei dem in bekannter Weise einer einfachen unverkitteten und ungleichschenkligen Zerstreuungslinse zwei in Luft stehende Sammelglieder voraufgehen, während auf der andern Seite der Zerstreuungslinse nur ein Sammelglied angeordnet ist, welches eine sammelnde Kittfläche aufweist. Dabei ist die Ausführung so getroffen, daß die Flächenbrennweite der Kittfläche kleiner als das Vierfache der Gesamtbrennweite der drei übrigen Linsen ist. Die Erfindung besteht darin, daß die Konstruktionsdaten die im Patentanspruch angegebenen Werte haben. Dadurch wird erreicht, daß innerhalb des Bildfeldes die Lagenabweichungen der sagittalen und meridionalen Bildflächen unter etwa 3/4 0% der Brennweite gehalten werden bei einer solchen Korrektion der sphärischen Abweichungen, daß deren größter zonischer Längsfehler unter etwa 3/ao% der Brennweite bleibt.Photographic lens The invention relates to a photographic lens Objective consisting of four limbs standing in the air, with which in the known way a simple one Unputted and unequal-sided diverging lens, two collecting links standing in the air go ahead, while on the other side of the divergent lens there is only one collecting member is arranged, which has a collecting putty surface. Here is the execution taken so that the focal length of the putty is less than four times is the total focal length of the three remaining lenses. The invention consists in that the design data have the values specified in the claim. This will achieves that the positional deviations of the sagittal and meridional image areas are kept below about 3/4 0% of the focal length with a such a correction of the spherical deviations that their greatest zonal longitudinal error remains below about 3 / ao% of the focal length.

Fig. r der Zeichnung zeigt das Objektiv nach der Erfindung in schematischer Darstellung. Die Bezeichnungen in Fig. 2 entsprechen denen des Patentanspruchs.Fig. R of the drawing shows the objective according to the invention in a schematic Depiction. The designations in Fig. 2 correspond to those of the claim.

Da die beiden vorderen Sammelglieder unverkittete Einzellinsen sind, trägt der Radius der Hinterfläche des zweiten Sammelgliedes II die Bezeichnung R4. Die sammelnde Kittfläche in dem bildseitigen Glied IV ist mit R$ bezeichnet. Die Konstruktionsdaten nach der Erfindung sind in folgender Zahlentafel angegeben, in welcher der Abstand der Gaußischen Bildebene vom bildseitigen Scheitel der letzten Linse L5 mit p', bezeichnet ist und die angegebenen Brechungsexponenten sich auf den gelben Strahl beziehen, während die Farbenzerstreuung durch die Abbesche Zahl v charakterisiert ist. Alle Längen sind unbezeichnet, so daß die Erfindung beliebige Werte für die Brennweite umfaßt.

All lengths are unmarked, so that the invention includes any values for the focal length.
