Claims

[Scope of utility model registration request]

Intensity uniformization processing in which the optical axis of the laser beam from the laser light source is arranged so that the optical axis of the quadrangular pyramidal prism coincides with the optical axis of the quadrangular pyramidal prism, and a beam with uniform intensity is irradiated onto the workpiece from the quadrangular pyramidal prism. The optical system includes a lens disposed between the laser light source and the quadrangular pyramidal prism so that their optical axes coincide with each other, and the lens directs the incident light beam of the laser beam to the quadrangular pyramidal prism. An intensity uniform processing optical system characterized by changing the diameter.
