Abstract
For defined ablation of a surface, successive partial regions of equal surface area are acted on by a radiation source, preferably a laser, through an optical system. The partial regions are smaller as regards surface area than the whole surface to be processed, so that the respective radiation source can be dimensioned in a less costly manner. Telescope optics with conical surfaces serve as optical systems suitable for this purpose.
