An optical processing head that detects a trouble of an optical processing head that will be generated at the time of optical processing before the trouble occurs is disclosed. The optical processing head that performs processing by condensing, on a process surface, a ray emitted by a light source for processing includes a cylindrical housing that surrounds a ray for processing emitted by the light source for processing, a ray emitter for inspection that is incorporated in the cylindrical housing and arranged outside the path of the ray for processing, and a light receiver that is incorporated in the cylindrical housing, arranged outside the path of the ray for processing, and receives a ray for inspection emitted by the ray emitter for inspection. The contamination of the inner surface of the cylindrical housing or the concentration of a scattering object flowing into the cylindrical housing is inspected by using a signal acquired from the light receiver.
An optical processing head that performs processing by condensing, on a process surface, a ray emitted by a light source for processing, comprising:
