Description

Photographisches Objektiv Es hat sich gezeigt, daß das Objektivsystem nach dem Patent 530 843 bei Anwendung für ein großes Gesichtsfeld störende komatische Erscheinungen aufweist. Ganz besonders stören die oberen komatischen Büschel, und zwar im Sinne einer starken positiven Überkorrektur. Untersuchungen haben ergeben, daß sich diese Erscheinungen durch die Einfügung einer sammelnden Kittfläche in das letzte Glied beheben lassen bei einer Differenz der Brechzahlen von mehr als o,i, wobei die Durchbiegung der Kittfläche so gelegt ist, daß sie ihre hohle Seite 55 dem Bilde zukehrt.

The upper comatic tufts are particularly disturbing, in the sense of a strong positive overcorrection. Investigations have shown that these phenomena can be remedied by inserting a collecting putty surface in the last link with a difference in the refractive indices of more than o, i, the curvature of the putty surface being arranged so that its hollow side faces the picture .
