Corner-cube-like reflector (1) for reflecting a laser beam under a pointed angle (ss, b') under a spatial version of the laser beam, witha reflector (RA),an intermediate reflector (RB); anda failure reflector (RC), where:the dipped-beam reflector (RA), the dipped-beam reflector (RB) and the dipped-beam reflector (RC) are arranged in such a way that the individual reflectors of a triple-beam reflector are not exactly orthogonal to one another;a laser beam falling along a corner-cube-like reflector (1) is reflected back along a failure beam (17);the failure radius (17) passes the drop radius (11) in a overlap area, in particular cuts,projections (11,17') of the input (11) and the output (17) on a rotational plane (R), parallel to the input (11), parallel to the output (17) and through the centre (D) of the shortest distance between the input (11) and the output (17), running in the rotation plane (R) below the point of diversion (ss, b');the impact reflector (RA) and the failure reflector (Rc) are modified in relation to an exact corner-cube retro reflector at an angle;the dipped-beam reflector (RB) is positioned at a angle of inclination modified with respect to the exact corner-cube retro-reflector and at a distance modified with respect to the exact corner-cube retro-reflector from the rotational plane (R) such that:an intermediate reflector reference point (B) given by the intersection point of an intermediate beam (13, 15) with the surface of the intermediate reflector (RB) is located at a distance (d2) modified from the rotational plane (R) with respect to the exact corner-cube retro-reflector.
