Description

Scheideprisma mit Meßmarken für stereoskopische und Koinzidenz-Enffernungsmesser Das Scheideprisma gemäß der Erfindung, das besonders für Binokular-Koinzidenz-Entfernungsmesser bestimmt ist, hat den Zweck, in den zwei Gesichtsfeldern (je eins pro Okular) das stereoskopische Sehen für eine oder mehrere zu einer einzigen Telemeterplatte gehörende Meßmarken zu bewerkstelligen, die sowohl in dem einen als auch im anderen der beiden Gesichtsfelder sichtbar sind.Divider prism with measuring marks for stereoscopic and coincidence range finders The separating prism according to the invention, which is particularly suitable for binocular coincidence range finders is determined, has the purpose in the two fields of view (one per eyepiece) the stereoscopic vision for one or more belonging to a single telemeter plate To accomplish measuring marks, both in one and in the other of the two Fields of view are visible.

Die Zeichnung gibt eine schematische Darstellung des Erfindungsgegenstandes, und zwar zeigen Fig. i das Scheideprisma im Aufriß von der Seite, Fig. 2 dasselbe Scheideprisma mit Meßmarken in der Stirnansicht nach der Einfallachse des vom Objektiv kommenden Strahlenbündels und Fig. 3 das Scheideprisma in schaubildlicher Darstellung, eingefügt in den Verlauf der Strahlen von zwei Objektiven bis zu den Okularen.The drawing gives a schematic representation of the subject matter of the invention, namely, Fig. 1 shows the separating prism in elevation from the side, Fig. 2 the same Separating prism with measuring marks in the front view according to the axis of incidence of the lens coming bundle of rays and FIG. 3 the separating prism in a diagrammatic representation, inserted in the path of the rays from two objectives to the eyepieces.

Das System ist durch drei Prismen i, 2 und 3 gebildet, welche an den Flächen q. und ii miteinander verkittet sind.The system is formed by three prisms i, 2 and 3, which are attached to the Areas q. and ii are cemented together.

Die gemeinsame Fläche ¢ ist teilweise versilbert, und zwar bis zur Trennungslinie 5, welche die Grenze zwischen den halbierten, im Telemeter auftretenden Gesichtsfeldern bildet.The common surface ¢ is partially silvered, up to Dividing line 5, which is the border between the halved, occurring in the telemeter Forms fields of view.

Auf derselben Fläche ist ferner eine gravierte, photographierte oder mit irgendeiner anderen Methode erzeugte Marke 6 vorgesehen, in der Weise, daß der untere Teil derselben sich in der Nähe des versilberten Teiles befindet. Zwei von zwei Objektiven in Richtung der Achsen 7 und 8 (vgl. Fig. i und 3) einfallende Strahlenbündel werden von- den Oberflächen der Scheideprismen z und 2 derart reflektiert, daß sie sich auf der Trennungslinie 5 kreuzen; durch zweckentsprechende Einstellung der Objektive werden die Bilder in der Nähe der Trennungslinie 5 erzeugt, und dadurch, daß alsdann die übrigen optischen Teile so angeordnet sind, daß man die Bilder binokular beobachten kann, wird man außer den äußeren Bildern auch die Marke 6 sehen; durch zweckmäßige Regulierung der Konvergenz wird die Marke im Raume im Relief auftreten, so daß sie für stereoskopische Messungen dienen kann.On the same surface there is also an engraved, photographed or Mark 6 generated by any other method is provided in such a way that the lower part of the same is located near the silver-plated part. Two of two lenses in the direction of the axes 7 and 8 (see. Fig. i and 3) incident beam are reflected by the surfaces of the separating prisms z and 2 in such a way that they cross on the dividing line 5; by appropriately setting the Lenses, the images are generated in the vicinity of the dividing line 5, and thereby, that then the other optical parts are arranged so that the images can be binocularly can be observed, one will also see the mark 6 in addition to the external images; by appropriate regulation of convergence, the mark will appear in space in relief, so that it can be used for stereoscopic measurements.

PATENTANSPRUCH: Scheideprisma für stereoskopische und Koinzidenz-Entfernungsmesser, dadurch gekennzeichnet, daß in seinem Innern nur eine einzige, mit einer oder mehreren Meßmarken versehene Telemeterplatte angebracht ist, deren Marke sich in der Nähe der Trennungslinie der zwei Gesichtsfelder befindet, in der Weise, daß die Marke oder die Marken in beiden Gesichtsfeldern sichtbar sind und so ein stereoskopisches Bild erzeugt wird, das im Telemeter außer den- monokularen und binokularen Koinzidenzmessungen auch die stereoskopische Messung der Bilder in bezug auf dieselben Marken gestattet.PATENT CLAIM: separating prism for stereoscopic and coincidence range finders, characterized in that in its interior only one, with one or more Telemeter plate provided with measuring marks is attached, the mark of which is in the vicinity the line dividing the two fields of view is located in such a way that the mark or the marks are visible in both fields of view and so a stereoscopic one Image is generated that in the telemeter except for monocular and binocular coincidence measurements also allows the stereoscopic measurement of the images with respect to the same marks.
