Description

Photographisches Teleobjektiv Der Erfindung liegt die Aufgabe zugrunde, ein photographisches Objektiv mit der Öffnung von etwa f : 5,6 für den Bildwinkel von etwa 4- 5' zu entwickeln, welches mit einer Brennweite von etwa 500 mm für. das Format 60 - 60 mm geeignet ist.A photographic telephoto lens of the invention is based on the object f a photographic lens with the aperture of about: 5.6 to develop the image angle of about 4- 5 ', which is mm with a focal length of about 500 for. the format 60 - 60 mm is suitable.

In Tabelle I (vgl. F i g. 1) sind die Baudaten für ein Objektiv angegeben, welches auf die Brennweite f = 500 abgeleitet werden kann und dann eine Lösung der Aufgabe darstellt. Die dabei sich ergebenden Linsen würden aber unnötig dick werden, so daß das Objektiv bei einer Brennweite von 500 mm unnötig schwer werden würde.In Table I (see FIG. 1) the construction data for an objective are given which can be derived from the focal length f = 500 and which then represents a solution to the problem. The resulting lenses would become unnecessarily thick, so that the lens would become unnecessarily heavy with a focal length of 500 mm.

Es ergibt sich also die weitere Aufgabe, bei einem Objektiv der in Tabelle 1 bezeichneten Art die Linsendicken merklich zu verringern und dann durch geeignete Änderung der -Lufträume und der Flächenbrechkräfte wieder einen guten Korrektionszustand herzustellen.There is thus the further task of noticeably reducing the lens thickness in an objective of the type specified in Table 1 and then restoring a good state of correction by changing the air spaces and the surface refractive powers appropriately.

Bei dem Objektiv der Tabelle II (vgl. F i g. 2) ist das geschehen. Auch Objektive, deren Baudaten nicht genau mit den in der Tabelle II angegebenen Daten übereinstimmen, sondern nur in der Nähe dieser Daten liegen, können einen etwa gleich guten Korrektionszustand aufweisen; es empfiehlt sich aber, so dicht bei den angegebenen Daten zu bleiben, daß keine der Brechkräfte (Anlr) dem Betrag nach um mehr als 0,20 - llf und keiner der Scheitelabstände (d) dem Betrag nach um mehr als 0,05 - f von dem jeweils betreffenden in der Tabelle 11 angegebenen Wert abweicht.
