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.

17. A sighting device for a surveying apparatus having angle measurement functionality, which sighting device comprises:
-
an objective unit, which defines an optical axis, and includes at least one optical component formed as a lens or as an optical plane-parallel plate; an image unit which includes a camera sensor and/or an eyepiece, for acquiring and/or providing an image of a sighted target object, an optical beam path being defined between the objective unit and the image unit; a transmission unit for emitting measurement beams as transmission beams and/or a reception unit for acquiring measurement beams as reception beams, and at least one optical deviation means for coupling the transmission beams into the optical beam path and/or for coupling the reception beams out of the optical beam path, wherein; the at least one optical component includes a cylindrical recess which extends in the direction of the optical axis; the deviation means includes a cylindrical fastening section extending inside the recess and corresponding in shape and size to the recess, so that a bonding gap is formed between the outer lateral face of the fastening section and at least a part of an inner lateral face, defined by the recess, of the optical component; and the deviation means is fastened indirectly to the at least one optical component by means of an adhesive contained in the bonding gap. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35)
