したことを特徴とするレーザ加工装置用光学系。 After dividing the laser light source and the laser light emitted from this laser light source into two by a half mirror, each laser light is focused by a separate condensing lens, and the sample placed at the converging point is simultaneously laser-focused. In an optical system for a laser processing device configured to perform processing, the laser light source generates linearly polarized laser light, and by rotating a glass plate set such that the incident angle of the laser light is the Brewster angle. An attenuator configured to adjust the amount of transmitted light is placed on at least one side of the laser beam path after the division into two,
An optical system for a laser processing device, characterized in that the optical system is configured so that the intensity of laser light at a condensing point is the same.
