Justiervorrichtung für Prismenfernrohre mit durch eine auf die Kante wirkende Feder auf dem Sitz gehaltenem Priema.
Die Erfindung dient dazu, das Justieren von Prismenfernrohren, bei denen das Prisma durch eine auf die Kante wirkende Feder auf dem Sitz gehalten wird, von aussen ohne Entfernung des Deckels zu ermöglichen. Dies geschieht mit einem von der Deckelseite aus zu betätigenden

In dem Ausführungsbeispiele der Fig. 2 wirkt die konische Fläche f der Schiaube e direkt auf die ihr angepasste Kante m des Prismas a lediglich im Sinne einer seitlichen Verschiebung ein.
In dem Ausführungsbeispiele der Fig. 3 ist als Vorschuborgan ein Exzenter n vorgesehen, welches fest mit der Schraube e verbunden ist. Durch Drehung der Sdmmbe 0 und der damit verbundenen Drehung des Exzenters n wird eine Verschiebung des Prismas je nach der Drehungsrichtung, entweder im Sinne der Einwirkung der Feder i oder im umgekehrten Sinne herbei- geführt.
Um die Verschiebung des Prismas auf seinem Sitz bei Anwendung eines Exzenters ohne gleichzeitige Veränderung der Höhenlage des Exzenters bewirken zu können, ist die in Fig. 4 bis6dargestellteEinrichtungvorgesehen.

Adjustment device for prism telescopes with priema held on the seat by a spring acting on the edge.
The invention serves to enable the adjustment of prism telescopes, in which the prism is held on the seat by a spring acting on the edge, from the outside without removing the cover. This is done with one that can be operated from the cover side

EMI1.3
In the exemplary embodiment in FIG. 2, the conical surface f of the slide e acts directly on the edge m of the prism a that is adapted to it, merely in the sense of a lateral displacement.
In the exemplary embodiment of FIG. 3, an eccentric n is provided as the feed member, which is firmly connected to the screw e. By rotating the Sdmmbe 0 and the associated rotation of the eccentric n, a displacement of the prism is brought about depending on the direction of rotation, either in the sense of the action of the spring i or in the opposite sense.
In order to be able to effect the displacement of the prism on its seat when an eccentric is used without simultaneously changing the height of the eccentric, the device shown in FIGS. 4 to 6 is provided.
