LASER PROCESSING APPARATUS AND LASER PROCESSING METHOD
摘要:
The present invention relates to a laser processing apparatus having a structure for effectively processing of objects by condensing a laser beam, and a laser processing method. A laser processing apparatus comprises a common mount surface on which plural objects are disposed in an array, a light source, a lens the reflection direction of which is changeable, and a condensing direction modifier. A laser beam from the light source arrives at the lens through a galvano-mirror. Herein, the galvano-mirror is arranged such that the reflection position thereof agrees with the front focal position of the lens. As the galvano-mirror reflects a laser beam toward the lens while the reflection direction is changed, the arriving position of the laser beam is scanned on the entrance surface of the lens. The condensing direction modifier modifies, according to the irradiation position of the laser beam arrived from the lens, an exit direction of the laser beam.
