SIGHTING DEVICE, IN PARTICULAR TELESCOPIC SIGHT, FOR A GEODETIC MEASURING APPARATUS AND OPTICAL OBJECTIVE UNIT ASSEMBLY FOR SUCH A SIGHTING DEVICE

摘要

The invention relates to a sighting device, inparticular to a telescopic sight, for a measuringapparatus having angular and in particular distancemeasurement functionality. The sighting device at leastcomprises an objective unit - defining an optical axis- having at least one lens, an image unit having acamera sensor and/or an eyepiece for capturing and/orproviding an image of a sighted target object, atransmitter for emitting measurement beams astransmitted beams and/or a receiver for capturingmeasurement beams as received beams, and at least oneoptical deflection means for coupling the transmittedbeams into the optical beam path of the sighting deviceand/or for coupling the received beams out of theoptical beam path. According to the invention, the atleast one lens comprises a cylindrical recess aroundthe optical axis, the recess extending in the directionof the optical axis. Furthermore, the deflection meanscomprises a cylindrical fastening section that extendsinside the recess such, and corresponds to the recesswith respect to shape and dimension such, that a gluinggap is created between the outer lateral surface of thefastening section and at least a portion of an innerlateral surface of the lens defined by the recess, andthe deflection means is fastened to the at least onelens, mediated by an adhesive located in the gluinggap.
