Beschreibung
Zusammenfassung:	An optical device for detecting the drift of a light beam of a laser machining system includes a beam splitter for obtaining a first light beam along a first optical path and a second light beam along a second optical path. The optical device further includes a focal module positioned at least partially along the first optical path to obtain a focused light beam that is directed towards a first light beam matrix detection means positioned in a focusing plane associated with the focal module. The optical device also includes an afocal module positioned at least partially along the second optical path to obtain a collimated light beam that is directed towards a second light beam matrix detection means.
