Abstract: This invention is directed to reliably condensing weak light by a sensor arranged at a position spaced apart from a processing position. The optical processing head includes a light guide that guides light for irradiating a processing position. The optical processing head further includes a light transmitter that has one end arranged near the distal end of the light guide and the other end connected to a photodetector, condenses reflected light traveling from the processing position, and transmits it to the photodetector. The optical processing head includes at least one light transmitter as its feature.

Abstract: This invention is directed to attenuating a beam output without changing the beam position and the beam diameter. A high-output optical attenuator includes a first reflector that totally reflects incident light and causes first reflected light serving as reflected light of the incident light to enter a second reflecting portion, a second reflector that reflects the first reflected light and causes second reflected light serving as reflected light of the first reflected light to enter a third reflecting portion, a third reflector that reflects the second reflected light and causes third reflected light serving as reflected light of the second reflected light to enter a fourth reflecting portion, and a fourth reflector that reflects the third reflected light as fourth reflected light having the same optical axis as the optical axis of the incident light. At least two of the second reflector, the third reflector, and the fourth reflector are half mirrors.
