Description

burchsichtssucher für photographische Kameras Die Erfindung bezieht sich auf einen Durchsichtssucher, welcher eine halbdurchlässig versilberte Fläche aufweist, die sich im negativen Bestandteil des Suchers befindet und die in ihrer Wirkung als reflektierende Fläche eine im bestimmten Abstand von dieser Fläche angebrachte Markierung unter Mithilfe der Brechkraft der in Frage kommenden Linsenflächen ins Unendliche abbildet.Viewfinder for photographic cameras The invention relates on a see-through viewfinder, which has a semi-permeable silver-plated surface which is in the negative part of the viewfinder and which is in their Effect as a reflective surface is one placed at a certain distance from this surface Marking with the help of the refractive power of the lens surfaces in question Infinite maps.

Der Sucher wird erfindungsgemäß nach Art eines umgekehrten galiläischen Fernrohres aufgebaut, wodurch sich infolge Verkleinerung des Gesichtsfeldwinkels ein müheloser Überblick des Gesichtsfeldes ermöglichen läßt.According to the invention, the viewfinder is designed in the manner of an inverted Galilean Telescope built up, which results in a reduction in the field of view angle allows an effortless overview of the field of view.

In der Zeichnung ist die Neuerung in einem Ausführungsbeispiel dargestellt. Zwischen den beiden negativen Bestandteilen r und a des Suchers befindet sich die halbdurchlässig versilberte Fläche 3. Im bestimmten Abstand zu diesen Linsen ist die Augenlinse4 angebracht. Die Markierung 5, die den Bildausschnitt wiedergibt, wird durch Reflektion in der halbdurchlässig versilberten Fläche sichtbar gemacht,In the drawing, the innovation is shown in an exemplary embodiment. Between the two negative components r and a of the finder is the semi-permeable silver-plated surface 3. At a certain distance from these lenses the eye lens4 attached. The marker 5, which shows the image section, is made visible through reflection in the semi-permeable silver-plated surface,
