Laser range finder having adjustable beam splitting optic and method for adjusting

A laser range finder for measuring a distance between a reference mark and a target object (1);

• the laser range finder comprises a beam source, a photodetector (2), and at least one beam shaping optic (3), an optic bracket (4), a circuit board (5), a beam splitting optic (6) and a connecting device (7);
• the beam source comprises a first electro-optical component (11) for emitting laser beam along an optical axis, the photodetector comprises a second electro-optical component for receiving a received beam reflected and/or scattered by the target object along an optical axis, the beam shaping optic is configured to form a laser beam (12) and/or a receiving beam (13) along an optical axis, the optic bracket comprises a first accommodating seat (41) for fixing the first electro-optical component (11) and a second accommodating seat (42) for fixing the at least one beam shaping optic, the circuit board comprises an additional accommodating seat (51) for fixing the second electro-optical component, the connecting device is configured to connect the optic bracket with the circuit board;
• wherein the beam splitting optic is arranged on an adjustment bracket (8), and the optic bracket comprises a third accommodating seat (45) for fixing the adjustment bracket;
• when adjusting the laser range finder, the first electro-optical component arranged in the optic bracket is adjustable relative to the optic bracket along the associated optical axis direction, and can be fixed at an adjusted position;
• further, the beam splitting optic arranged on the adjustment bracket is adjustable relative to the optic bracket and can be fixed in an adjusted position.
