特徴とするレーザマーキング用光学系。 In a laser marking optical system, the beam emitted from the laser light source is expanded by a beam shaping means to match the shape of the mask, and the pattern formed on the reflective mask is imaged by a lens. A laser marking optical system characterized by using a beam shaping means of a non-collimating optical system so that the beam does not converge near the light source after returning to the beam shaping means.
