Description

Objektiv Es ist häufig erforderlich, die Hauptebenen eines optischen Systems zu verlagern, ohne merkbare Abbildungsfehler in das Ganze Zu diesem Zweck sind schon 1-Wfslinsen benutzt worden, deren Restfehler dadurch beseitigt wurden, daß man entgegengesetzte Fehler in das optische Ausgangssystem einführte.Lens It is often necessary to understand the main planes of an optical To relocate the system without noticeable aberrations in the whole. For this purpose 1-Wfs lenses have already been used, the residual errors of which have been eliminated, that opposite errors were introduced into the output optical system.

Die Erfindung richtet sich auf ein Objektiv, in dessen vorderer Brennebene ein Farbivählsystem zur Aufnahme oder Wiedergabe von Linsenrasterfilm:en angeordnet ist. Für diese Zwecke 'hat man bereits Objektive mit optischen Zusatzsystemen vereinigt, die man vor das eigentliche Objektiv gestellt hat. Solche Zusatzsysteme bestanden z. B. aus einer Negativ- und einer Positivlinse und dienten dazu, eine Vergrößerung des Bildfeldes zu erzielen. Auch sind schon Zusatzsysteme benutzt worden, die sich zwischen Objektiv und hinterer Brennebene befanden. Beim Erfindungsgegenstand ist das Zusatzsystem ebenfalls an dieser Stelle vorgesehen. Nur 'besteht es gemäß der Erfindung nach Art eines Teleobjektivs aus einem negativen und einem positiven Gliede, von denen der negative Bestandteil dem eigentlichen Objektiv zugekehrt ist. Sowohl das negative wie auch das positive Glied können korrigiert sein.The invention is directed to a lens in the front focal plane a color counting system for recording or reproducing lenticular lenticular film: s arranged is. For these purposes, lenses have already been combined with additional optical systems, which one has placed in front of the actual lens. Such additional systems existed z. B. from a negative and a positive lens and were used to enlarge of the image field. Additional systems have also been used that are between the lens and the rear focal plane. The subject of the invention is the additional system is also provided at this point. Only 'it exists according to the Invention in the manner of a telephoto lens consisting of a negative and a positive element, of which the negative component is turned towards the actual objective. As well as the negative as well as the positive term can be corrected.

Die beiden Glieder können dieselbe Brennweite besitzen. Sie können auch verschiedene Brennweiten haben und zueinander so angeordnet sein, daß sie ein afokales (teleskopisches) System bilden, bei dem das negative Glied und das positive Glied einen Brennpunkt gemeinsam haben.The two members can have the same focal length. You can also have different focal lengths and be arranged in relation to one another so that they have a form afocal (telescopic) system, in which the negative link and the positive Member have a focus in common.

Die Figur der Zeichnung stellt beispielsweise ein Telenegativ A dar, das mit einem Telepositiv B so hinter einem Objektiv O (in der Figur punktiert gezeichnet) angeordnet ist, daß das negative Glied A dem Objektiv 0 benachbart ist. Mit dieser Einrichtung läßt sich der vordere Brennpunkt des Gesamtsystems sehr nahe an die vordere Linse des Objektivs O rücken, was deshalb von Vorteil ist, weil dann die Abschattung des an dieser Stelle stehenden Farbwahlsystems durch Linsenfassungen o. dgl. wesentlich leichter zu vermeiden ist, als wenn das Filter weit vom Objektiv entfernt wäre.The figure in the drawing shows, for example, a telephoto negative A, that with a telepositive B so behind a lens O (shown in dotted lines in the figure) is arranged that the negative member A is adjacent to the lens 0. With this The front focal point of the overall system can be very close to the device move the front lens of the objective O, which is advantageous because then the Shading of the color selection system at this point by lens mounts or the like is much easier to avoid than if the filter is far from the lens would be removed.

PATENTANSPRÜCHE: z. Objektiv, in dessen vorderer Brenn--ebene ein Farbwahlsystem angeordnet ist und bei dem sich zwischen Objektiv und hinterer Brennebene ein Zusatzsystem befindet, dadurch gekennzeichnet, daß das Zusatzsystem nach Art eines Teleobjektivs ausgebildet ist, dessen negativer Bestandteil dem eigentlichen Objektiv zugekehrt ist. PATENT CLAIMS: e.g. Lens in its front focal plane Color selection system is arranged and in which between the lens and the rear focal plane an additional system is located, characterized in that the additional system according to Art a telephoto lens is formed, the negative part of which is the actual Objectively facing. 2. Objektiv nach Anspruch i, dadurch gekennzeichnet, daß das negative Glied und das positive Glied des Zusatzsystems zur Bildung eines teleskopischen Systems einen Brennpunkt gemeinsam haben.2. Lens according to claim i, characterized in that the negative link and the positive link of the additional system to form a telescopic Systems have a common focal point.
