ABSTRACT:
A laser beam receiver including a transparent disc and a mirror arrangement which are fastened on a base element. A light spot formed on the disc by a laser beam may only be seen optimally, particularly if the distance between the laser device and the laser beam receiver is so great that the laser beam arrives only faintly, if the observer's angle of view lies in the axial extension of the laser beam. The mirror is so arranged that this angle of view lies exactly in the axial extension of the laser beam. The range of action of the laser device is thus expanded in a simple and inexpensive manner.
