 reflektierenden Flächen ausgebildet, um in an sich bekannter Weise die Parallelität der einund austretenden Lichtstrahlen auch bei Verdrehung des Rohres 8 zu sichern. 



     D : ts neue Instrument ermöglicht   in bequemer Weise die Beobachtung aus gedeckter Stellung. Wenn dabei die Verwendung in nach oben hin abgedeckten Räumen in Frage kommt, die mit senkrecht zur vorgeschriebenen Visierrichtung versehenen   Durchtrittsönfungen   für die Ansatzrohre   8,   9 versehen sind, dann empfiehlt sich eine solche Anordnung der vorgelagerten Reflektoren und dementsprechend auch der Endreflektoren des   Basisentfernungsmessers,   dass die Lichteintrittsrichtung schräg zum   Basiarohr Hegt.   



   PATENT-ANSPRÜCHE :
1. Basisentfernungsmesser mit gehobenen   Lichteintrit, tsöffnungen   und den Lichtablenkungskörpern an den Basisenden vorgelagerten Reflektoren, dadurch gekennzeichnet, dass die vor- gelagerten Refiektoren auf entgegengesetzten Seiten des Basisrohres angeordnet sind.

 reflective surfaces in order to ensure, in a manner known per se, the parallelism of the incoming and outgoing light beams even when the tube 8 is rotated.



     D: t's new instrument makes it easy to observe from a covered position. If it is possible to use them in rooms that are covered at the top and are provided with openings for the extension tubes 8, 9 perpendicular to the prescribed direction of sight, then such an arrangement of the upstream reflectors and, accordingly, of the end reflectors of the base rangefinder is recommended that the Direction of light entry at an angle to the basal tube.



   PATENT CLAIMS:
1. Basic rangefinder with raised light inlet, openings and reflectors upstream of the light deflection bodies at the base ends, characterized in that the upstream reflectors are arranged on opposite sides of the base tube.

Claims (1)

2. Basisentfernungsmesser nach Anspruch 1, dadurch gekennzeichnet, dass die der einen Lichteintrittsöfnnung des Entfernungsmessers vorgelagerten Reflektoren, durch welche das eintretende Licht gegenläufig zu seiner Eintrittsrichtung nach dem eigentlichen Entfernung- messer entlassen wird, drei Reflexionsflächen enthalten, welche so zueinander angeordnet sind, EMI2.1 2. Basic rangefinder according to claim 1, characterized in that the reflectors upstream of the one light entry opening of the rangefinder, through which the entering light is released in the opposite direction to its entry direction after the actual rangefinder, contain three reflective surfaces which are arranged in relation to one another, EMI2.1
