Abstract

A system for processing a portion in a processing volume of a transparent material by application of focused radiation including a device for generating and an optical system for focusing radiation, with a device for changing the position of the focus of the radiation and a control device. The system includes a controller that controls the ophthalmologic therapy system. The controller is encoded with a scan pattern. The scan pattern includes adjacent strokes with each adjacent stroke having an angle of inclination (α) to the beam axis; and the angle of inclination (α) of the strokes to the beam axis is always larger than or equal to the focal angle (φ) of the focused radiation.
