Title:
PROCESSING HEAD AND LASER PROCESSING MACHINE
Document Type and Number:
WIPO Patent Application WO/2017/203613
Kind Code:
A1
Abstract:
A processing head (1) applies, to an object (W) to be processed, a laser beam (L) produced through oscillation by a laser oscillator (200). The processing head (1) is provided with a processing lens (20) that condenses the laser beam (L). The processing head (1) is provided with an optical component (40) that is arranged so as to be rotatable, around a rotation axis (41) intersecting with an axis (AX) parallel to an optical axis (P0) of the processing lens (20), between a protruding position (SL) through which the laser beam (L) that has been oscillated by the laser oscillator (200) and that is to enter the processing lens (20) passes, and a withdrawn position (EL) away from the laser beam (L).
