A device for representing the direction of action ( 9 ) of a working means ( 3 ), in particular a tool or a radiation source and/or a radiation emitter, for example, of X-rays is provided. The device includes a first light source ( 4 ) which is used to produce a first beam ( 5 ). In order to represent the direction of action in a continuous manner, at least one additional light source ( 4 ') which is used to produce an additional beam ( 5 ') is provided. The light sources ( 4 , 4 ') and the working device ( 3 ) can be oriented in such a manner that the first beam ( 5 ) and the additional beam ( 5 ') have a flat extension and cut in the direction of action ( 9 ) of the working means ( 3 ). The invention also relates to a corresponding method.
