Description
Entfernungsmesser mit Meßlatte. Gegenstand der Erfindung ist eine Abänderung des Gerätes zum Messen der Entfernung mit einer Meßlatte nach dem Patent 342658.Range finder with measuring stick. The invention is a Modification of the device for measuring the distance with a measuring stick according to the patent 342658.
Gemäß der Erfindung sind die zwei Paare paralleler Spiegel nach dem Hauptpatent durch zwei Planparallelplatten ersetzt.According to the invention, the two pairs of parallel mirrors are after Main patent replaced by two plane parallel plates.
Die Zeichnung zeigt eine beispielsweise Ausführungsform des Erfindungsgegenstandes, und zwar zeigt Abb. i einen Längsschnitt durch das Okularende des Fernrohres mit der eingebauten neuen Einrichtung, Abb. 2 einen Querschnitt nach Linie II-II in Abb. i.The drawing shows an exemplary embodiment of the subject matter of the invention, namely Fig. i shows a longitudinal section through the eyepiece end of the telescope of the built-in new device, Fig. 2 a cross-section along line II-II in Fig.i.
Mit ua sind die durch die paarweise parallelen Flächen a, a1 und a', ai begrenzten, Lichtstrahlen brechenden Körper bezeichnet. Es sind Glas- oder Quarzkörper von rechteckiger Grundfläche. Die beiden Körper m sind um gleiche Winkel gegen die Bildebene der Objektivlinse o geneigt und derart angeordnet, daB die in strichpunktierten Linien angedeuteten Bildstrahlen zweier verschiedener Teilstriche der beobachteten Meßlatte beim Durchgang durch die Körper m derart gebrochen werden, daß diese beiden Teilstriche vom Beobachter in einer und derselben Linie liegend gesehen werden. Die Körper in sind im Tragestück t befestigt. Zur Höhenbestimmung sind Marken n oder Fäden f vorgesehen. Die Neigung der Körper gegen m wird zweckmäßig nicht zu groß gewählt, da sonst viel von der Lichtstärke durch Reflexion verlorengeht.The light beam refracting bodies delimited by the pairwise parallel surfaces a, a1 and a ', ai are designated by ua. They are glass or quartz bodies with a rectangular base. The two bodies m are inclined at the same angle to the image plane of the objective lens o and are arranged in such a way that the image rays of two different graduation lines of the observed measuring stick, indicated in dash-dotted lines, are refracted when passing through the body m in such a way that these two graduation lines are broken into one by the observer and can be seen lying on the same line. The bodies in are fastened in the carrying piece t. Marks n or threads f are provided to determine the height. The inclination of the body towards m is expediently chosen not to be too great, since otherwise much of the light intensity is lost through reflection.
Es ist ferner zweckmäßig, wenn die Körper m sich seitlich bis an den inneren Umfang des Tragestückes t erstrecken, so daß die beiden Gesichtsfeldhälften des Fernrohres durch die Körper m ausgefüllt sind.It is also useful if the body m is laterally up to the inner circumference of the support piece t extend so that the two halves of the field of view of the telescope are filled by the body m.
Die die Lichtstrahlen brechenden Körper könnten auch aus einer Flüssigkeit bestehen, die in durchsichtigen prismatischen Behältern, welche zwei paarweise parallele Flächen aufweisen, eingeschlossen ist.The bodies refracting the light rays could also consist of a liquid exist in transparent prismatic containers, which are two parallel pairs Have surfaces, is included.
