Description

Die Erfindung bezieht sich auf einen Trennbildentfernungsmesser nach Patent 899423. DasPatent 899 423 bezieht sich auf einen Entfernungsmesser, bei dem in der Zwischenabbildungsebene seiner Fernrohroptik ein den seitlichen Entfernungsmesserstrahlengang in die gerade Durchsicht einlenkender Spiegel angeordnet ist. Um nun bei dieser Einrichtung das seitliche Entfernungsmesserbild mit scharfen Konturen zu erhalten, wird zwischen das einlenkende optische Mittel und das zugehörige, seitlich davon hinter der Strahleneintrittsöffnung stehende spiegelnde -Element ein weiteres spiegelndes Element so angeordnet, daß der Winkel zwischen dem Hauptstrahl der geraden Durchsicht und dem Hauptstrahl des seitlichen Bildes sehr klein wird. Auf diese Weise wird erreicht, daß das in der Zwischenabbildungsebene stehende, Strahlen einlenkende optische Mittel nahezu in der Zwischenabbildungsebene selbst liegt.The invention relates to a separator image range finder according to Patent 899423. Patent 899,423 relates to a range finder in which In the intermediate image plane of his telescope optics, the lateral rangefinder beam path is arranged in the straight through view deflecting mirror. To now at this Facility to maintain the lateral rangefinder image with sharp contours, is between the deflecting optical means and the associated one to the side of it behind the beam entrance opening is another reflective element Element arranged so that the angle between the principal ray is straight through and the main ray of the side image becomes very small. That way will achieves that the beam deflecting in the intermediate imaging plane optical means is almost in the intermediate imaging plane itself.

Nach vorliegender Erfindung wird nun diese Einrichtung weiterhin dadurch verbessert, daß man eine in der Nähe der Zwischenabbildungsebene liegende Linse des Fernrohres in die gleiche Schrägstellung wie das Strahlen einlenkende optische Mittel schwenkt und das als Spiegel ausgebildete Strahlen einlenkende Mittel mit dieser Linsenfläche verbindet. In der praktischen Ausführung wird man die Verspiegelung unmittelbar auf die vorzugsweise plan zu haltende Linsenfläche aufbringen und dann rückseitig mit Lack abdecken.According to the present invention, this device is now further thereby improved by having a lens located in the vicinity of the intermediate image plane of the telescope in the same inclination as the beam deflecting optical The means pivots and the means, which is designed as a mirror, also deflects the rays this lens surface connects. In the practical implementation one becomes the mirroring apply directly to the lens surface, which is preferably to be kept flat, and then Cover the back with varnish.

In der Zeichnung ist die Erfindung in einem Ausführungsbeispiel dargestellt.In the drawing, the invention is shown in one embodiment.

Der das große Gesichtsfeld des Entfernungsmessers erzeugende Strahlengang tritt durch das Dachkantprisma i ein und wird durch die Linse 2, die Prismenkombination 3, 4 und die Linse 5 zur Abbildung in die Zwischenabbildungsebene 6 weitergeleitet. Das in dieser Ebene erzeugte aufrechte und seitenrichtige Bild wird durch das aus den Linsen 7 und 8 bestehende Okular betrachtet. Der seitliche Strahlengang verläuft über das Prisma 9, Doveprisma i o, Linse ii und Prismenkombination 12 und 13, um dann von dem auf die Planfläche 14 der Linse? aufgetragenen Spiegel 15 in den Hauptstrahlengang eingelenkt zu werden. In der Zwischenabbildungsebene ist die verstellbare Gesichtsfeldblende 16 angeordnet.The beam path generating the large field of view of the rangefinder enters through the roof prism i and is passed on through the lens 2, the prism combination 3, 4 and the lens 5 for imaging in the intermediate imaging plane 6. The upright and laterally correct image generated in this plane is viewed through the eyepiece consisting of lenses 7 and 8. The lateral beam path runs over the prism 9, doveprism io, lens ii and prism combination 12 and 13 in order to then move from the to the plane surface 14 of the lens? applied mirror 1 5 to be deflected into the main beam path. The adjustable field diaphragm 16 is arranged in the intermediate imaging plane.
