Japanese Patent JP5841031

Kind Code:

B2

Abstract:

Provided is an optical processing device including: a beam emission portion which includes a plurality of optical fibers; a dispersion element which disperses a beam emitted from one optical fiber of the plurality of optical fibers; a condenser lens which concentrates the beam passing through the dispersion element; and an optical path conversion optical system which converts an optical path of the beam passing through the condenser lens so that the beam is incident to one of the other optical fibers of the plurality of optical fibers. An optical axis of the condenser lens is inclined with respect to an optical axis direction from the beam emission portion to the optical path conversion optical system. The inclination angle is set so that a maximum difference in focal depth of a plurality of beams having different wavelengths obtained by the dispersion element becomes smaller.
