Abstract
An optical processing apparatus includes a light source, a condensing lens, and a light shield. The light source emits a light. The condensing lens converts a light emitted from the light source into a Bessel beam and condenses the light onto a surface of an object. The light shield shields an outer edge portion of the light in a cross section of a direction orthogonal to the optical axis of the light. The light shield may shield the outer edge portion of the light after entering the condensing lens and before condensing onto the surface of the object in the cross section of the direction orthogonal to the optical axis of the light.
