 wirken, Die Kollimatoren   tnl und P   sind durch die Befestigung der Skalenobjekte m1 und m2 auf den Sammellinsen 11 und P zu einem   Doppelkollimatol   vereinigt, dessen beide Achsen eine unverrückbare gegenseitige Lage haben. Die beiden fernen virtuellen Bilder der Skalenobjekte m1 und m2 werden, durch zwei kleine Winkelspiegelprismen s1 und s2 von derselben Anordnung wie in Fig. 2 in die den beiden Fernrohren entsprechenden Objektrichtungen verlegt. Die Okulare sind   ähnlich   wie in Fig. 2 angeordnet. 



   PATENT-ANSPRUCHE :   I.   Entfernungsmesser mit zwei Fernrohren und einem Messmarkensystem in jedem Bildfeld. dadurch gekennzeichnet, dass mindestens ein   Messmarkensystem aus einem reellen optischen   Bild besteht, das aus einem in der Objektrichtung liegenden, fernen virtuellen Markenbild von

 The collimators tnl and P are united by the attachment of the scale objects m1 and m2 on the converging lenses 11 and P to a double collimatol, the two axes of which have an immovable mutual position. The two distant virtual images of the scale objects m1 and m2 are moved by two small corner mirror prisms s1 and s2 from the same arrangement as in FIG. 2 in the object directions corresponding to the two telescopes. The eyepieces are arranged in a manner similar to that in FIG.



   PATENT CLAIMS: I. Rangefinder with two telescopes and a measuring mark system in each field of view. characterized in that at least one measurement mark system consists of a real optical image, which consists of a remote virtual mark image from in the direction of the object
 EMI3.1
 of the measuring mark system.

Claims (1)

2. Entfernungsmesser nach Anspruch 1, bei dem nur ein Messmarkensystem ein reelles Bild ist, dadurch gekennzeichnet, dass das virtuelle Markenbild aus dem physischen Messmarken system des andern Bildfeldes unter Beihilfe eines Spiegelprismensystems von den optischen Teilen erzeugt wird, die im andern Bildfeld das Objektbild entwerfen, so dass auch Lageänderungen EMI3.2 Messmarkensystems gegen sein Objektbild ausgeglichen wird. 2. Rangefinder according to claim 1, in which only one measuring mark system is a real image, characterized in that the virtual mark image is generated from the physical measuring mark system of the other image field with the aid of a mirror prism system from the optical parts that design the object image in the other image field so that also changes in location EMI3.2 Measuring mark system is balanced against its object image. 3. Entfernungsmesser nach Anspruch 1, bei dem beide Messmarkeiisysteme reelle Bilder sind, dadurch gekennzeichnet, dass die virtuellen Markenbilder von einem einzigen Kollimator unter Beihilfe eines Spiegelprismensystems erzeugt werden, so dass die Verschiebung des Mess- markensystems gegen das Objektbild, die durch eine Richtungsänderung der Kollimatorachse verursacht wird, in beiden Bildfeldern mit gleicher Grösse und Richtung auftritt. EMI3.3 3. Range finder according to claim 1, in which both measuring marking systems are real images, characterized in that the virtual mark images are generated by a single collimator with the aid of a mirror prism system, so that the displacement of the measuring mark system against the object image caused by a change in direction Collimator axis is caused, occurs in both image fields with the same size and direction.
