Optical system for laser beam machining - exchanges optical system used for work-surface observation with high power system for quality control in same axis

In a laser processing system, a laser beam is deflected by a transport mirror and a focusing deflectable lens on to the workpiece, or an organ for medical treatment. An observation system is arranged coaxial to the mirror, using the laser lens. A swivellable high-quality objective lene system is pos...

Beschreibung
Zusammenfassung:	In a laser processing system, a laser beam is deflected by a transport mirror and a focusing deflectable lens on to the workpiece, or an organ for medical treatment. An observation system is arranged coaxial to the mirror, using the laser lens. A swivellable high-quality objective lene system is positioned between the mirror and the ocular system, with an image plane which coincides with that of the laser lens. The two lenses are coupled so that they arer alternately in the beam path. ADVANTAGE - Accurate positioning and guidance of laser beam.
