A device for drilling and for removing material using a laser beam comprises: a rotating image rotator (); a beam manipulator () which, when viewed in the beam direction, is arranged in front of the image rotator and which serves to adjust the angle and position of the beam relative to the rotation axis of the image rotator; and a focusing device () located on the output side of the image rotator. A compensating device () is placed between the image rotator and the focusing device and rotates with the image rotator in the same direction of rotation and with the same rotational frequency. The compensating device has a parallel displacement unit () and an angle changing unit (), and the compensating device, in a basic setting, is adjustable in its rotating position relative to the image rotator.
