LENS APPARATUS FOR LASER MACHINING AND LASER MACHINING APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide a lens apparatus for laser machining and a laser machining apparatus, enabling the use according to a plurality of machining applications by a single machining apparatus.

SOLUTION: The lens apparatus for laser machining 10 includes a lens holder 11 which is attachably/detachably mounted on a head part 2 of a laser beam marker 1 for machining a workpiece W by condensing the laser beam by an fθlens 2e. An auxiliary lens 12 for changing the angle of the laser beam emitted from the fθlens 2e with respect to the optical axis X is fitted to the lens holder 11.
