The present disclosure provides a sensor arrangement for reflecting scattered light from a laser beam. The sensor arrangement comprises a first optical element; a cone of a housing disposed behind the first optical element in the direction of the beam path of a laser beam, where the cone of the housing comprises a conical staircase-shaped reflector whose shape corresponds to the shape of the cone of the housing, and where the conical staircase-shaped reflector is formed of a plurality of ring-shaped elements, with each ring-shaped element having reflector surfaces on the inner side facing the beam path of the laser beam; and an element for receiving the light reflected by the respective reflector surfaces of the plurality of ring-shaped elements is arranged on the side of the optical element opposite to the cone of the housing.
