摘要： To prevent an output decrease of laser light due to impurities that could be formed in a guide-light emitting device or an imaging device. A laser-light guiding section includes a transmission window section, an optical component disposed to cause an optical path of the UV laser light emitted from the laser-light output section and an optical path of transmitted light transmitted through the transmission window section to cross, and a sealing member in which the transmission window section is provided, the sealing member configuring a sealed space for airtightly housing the optical component. At least one of a guide-light emitting device configured to emit guide light for visualizing a scanning position of the UV laser light toward the transmission window section and an imaging device configured to receive light for imaging a workpiece via the transmission window section is disposed on the outer side of the sealed space.
