Abstract
Methods and apparatus for extending the lifetime of optical components are disclosed. A beam of laser energy directed along a beam path that intersects a scan lens, through which it can be transmitted. The beam path can be deflected within a scan region of the scan lens to process a workpiece with the laser energy transmitted by the scan lens. The scan region can be shifted to a different location within the scan lens, e.g., to delay or avoid accumulation of laser-induced damage within the scan lens, while processing a workpiece.
