PROBLEM TO BE SOLVED: To provide a laser processing head including a function capable of imaging a laser processing position without causing halation.SOLUTION: In a laser processing head including: a condensing lens 47 to focus a laser beam oscillated from a laser oscillator; a protective glass 89 to protect the condensing lens 47 from spatters and the like scattering from a laser processing position; imaging means 81 to image the laser processing position; and lighting means 95 to illuminate an imaging position of the imaging means 81, ring-shaped lighting means 95 is provided between the condensing lens 47 and the protective glass 89, and a shading member 97 is provided inside of the ring-shaped lighting means 95 to block an illumination light directly entering from the lighting means 95 and a reflection light reflected on the protective glass 89 into the imaging means 81 provided above the protective glass 89. The shading member 97 has a cylindrical shape and includes an optical reflection surface 99 to reflect the illumination light from the ring-shaped lighting means 95 to a tip side of the laser processing head on a circumferential surface thereof. |
