OPTICAL DEVICE FOR BORING USING A LASER BEAM

摘要

An optical drilling device using a laser beam (5), having an optical arrangement located in the beam path for guiding the laser beam (5) along a circular cutting path and a focusing lens system (6) located downstream from the arrangement and focusing the laser beam (5) onto a workpiece (7). Maintaining a simple design, the various parameters can be easily set by providing the optical arrangement with a separately rotatable image rotator (4) which guides the beam along the cutting path.
