Device for drilling and for removing material using a laser beam

A device for drilling and for removing material using a laser beam, said device comprising, in combination:

• a rotating image rotator;
• a beam manipulator which, when viewed in the beam direction, is arranged in front of the image rotator and serves to adjust the angle and position of the beam relative to the rotation axis of the image rotator;
• a focusing device located on the output side of the image rotator;
• and
• a compensating device, disposed between the image rotator and the focusing device, that rotates with the image rotator in the same direction of rotation and with the same rotational frequency, the compensating device comprising a parallel displacement unit and an angle changing unit;
• wherein the parallel displacement unit comprises a plane-parallel plate which is arranged directly after the image rotator and is rotatable in a direction perpendicular to the rotation axis;
• wherein the angle changing unit comprises two wedge plates, each being rotatable in a direction perpendicular to the rotation axis;
• and
• wherein the compensating device is adjustable in its rotating position relative to the image rotator in a basic setting.
