   Bei der normalen Beobachtung befindet sich der Schieber 11 in der in der Zeichnung dargestellten Lage, wobei die planparallelen Glasplatten 9, 10 in den Strahlengang eingeschaltet sind. In diesem Falle erfolgt die Abbildung unendlich ferner Objekte in den Ebenen der   Messmarkenplatten 7, 8. Für   den Zweck der Berichtigung nach einer in endlicher Entfernung aufgestellten Latte wird der Schieber 11 so verschoben, dass die Blenden   12, 13   in die Arbeitsstellung geraten.

   Die Ausschaltung der Glasplatten   9,   10 bewirkt eine Verlagerung der Bildebenen der   Objektive   6, so dass diese für unendlich ferne Objekte nicht mehr mit den Ebenen der   Messmarkenplatten   7, 8 zusammenfallen würden, sondern ein wenig vor diesen Ebenen, d, h. von den Okularen   3, 4 weg   gerückt, liegen würden. Wenn dann aber das Instrument anstatt auf unendlich ferne Objekte auf eine in endlicher, passender Entfernung liegende Berichtigungslatte eingestellt würde, dann verschieben sich entsprechend dieser endlichen Entfernung die Bilder in die Messmarkenebenen 7, 8. 



   PATENT-ANSPRÜCHE : i. Stereoskopischer Entfernungsmesser mit   Einrichtung ur Berichtigung desbfiben,   dadurch gekennzeichnet, dass diese Einrichtung aus der an sich bekannten, in endlicher Entfernung aufstellbaren Messlatte und vor dem   Okular angeotdneten auschaltbaren plan-   parallelen Platte besteht, zum Zwecke, die Parallaxe zwischen den Bildern der Lattenmarken und den Messmarken zu verhüten.

   During normal observation, the slide 11 is in the position shown in the drawing, the plane-parallel glass plates 9, 10 being switched into the beam path. In this case, the imaging of infinitely distant objects takes place in the planes of the measuring mark plates 7, 8. For the purpose of correction after a staff set up at a finite distance, the slide 11 is shifted so that the diaphragms 12, 13 move into the working position.

   Switching off the glass plates 9, 10 causes the image planes of the objectives 6 to be shifted so that, for objects at an infinite distance, they would no longer coincide with the planes of the measuring mark plates 7, 8, but a little in front of these planes, i.e. moved away from the eyepieces 3, 4. If, however, the instrument were then set to a correction staff at a finite, suitable distance instead of objects at an infinite distance, then the images shift into the measuring mark planes 7, 8 according to this finite distance.



   PATENT CLAIMS: i. Stereoscopic rangefinder with device for correction desbfiben, characterized in that this device consists of the known measuring rod, which can be set up at a finite distance, and a plane-parallel plate that can be switched off in front of the eyepiece for the purpose of creating parallax between the images of the staff marks and the measuring marks to prevent.

2. Entfernungsmesser nach Anspruch i, dadurch gekennzeichnet, dass die planparallele Glasplatte derart mit einer Blende verbunden ist, dass beim Ausschalten der Glasplatte diese durch die Blende ersetzt wird bzw. werden kann. 2. Distance meter according to claim i, characterized in that the plane-parallel glass plate is connected to a diaphragm in such a way that when the glass plate is switched off, it is or can be replaced by the diaphragm.
