Abstract
A sighting device includes an objective unit, an image unit, a transmitter for emitting measurement beams as transmitted beams and/or a receiver for capturing measurement beams as received beams, and at least one optical deflection means for coupling the transmitted beams into the optical beam path of the sighting device. The at least one lens comprises a cylindrical recess around the optical axis, the recess extending in the direction of the optical axis. Furthermore, the deflection means comprises a cylindrical fastening section that extends inside the recess such that a gluing gap is created between the outer lateral surface of the fastening section and at least a portion of an inner lateral surface of the lens defined by the recess, and the deflection means is fastened to the at least one lens, mediated by an adhesive located in the gluing gap.
