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.

The invention relates to a method for high-precision fixing of a miniaturized component (), in particular having a microoptical element (), on a predetermined fixing section () of a support plate () by a solder joint. The support plate is formed throughout from a metallic material and has a cut-out region () which encloses the fixing section (), is bridged by at least one connecting web () of the support plate (), keeps the heat transfer from the fixing section () to the remaining support plate low and compensates lateral thermal expansions of the fixing section (). Solder material () is applied on the top of the fixing section (). The method comprises in particular the steps: arrangement of the component () above the fixing section (), the solder material () and the base () of the component () being present in opposite positions without contact and forming a space. Supply of electromagnetic radiation () to the bottom () of the fixing section () for melting the solder material (') so that, as a result of drop formation and optionally as a result of lowering of the component () the space fills with molten solder material (&#x2032;) for mutual fixing. Waiting for the mutual fixing by resolidification of the molten solder material (&#x2032;).

In order to improve target illumination, a light source () of an emitter, which has a laser diode () configured as an edge emitter with a wavelength of 1,550 nm, has beam forming optics () mounted downstream in relation thereto, which comprise a cylindrical lens () and a first deflection element () with three fields having different diffraction structures. Said deflection element are located next to one another and crosswise in relation to the first fields and which also have different diffraction structures. Said deflection element directs the partial beams to the aperture of a collimator () in such a way that the partial beams substantially fill said aperture. The first deflection element () and a mount () for the cylindrical lens () are integral and, alike the second deflection element (), are made of plastic. Both parts are glued to opposite sides of the frontal areas of a block () made of glass.
