摘要:
A fan/filter unit includes a casing having formed an air outlet port on a front side thereof and an air inlet port on a rear side thereof; a fan housed in the casing so as to face the air inlet port; a filter housed in the casing so as to face the air outlet port such that the air discharged by the fan in a widthwise direction of the casing is blown forward through the filter. The fan/filter unit has a shielding plate disposed between the fan and the filter as seen in a depthwise direction of the casing so that the shielding plate shields an associated flow of air flowing in a direction from the filter to the fan.

The laser processing apparatus includes lasers for emitting a plurality of laser beams of different wavelengths, a common phase grating for splitting the laser beams of different wavelengths into diffraction beams shaped in designed arrays, and a condenser lens for condensing the diffraction beams. The layout of the focused diffraction beam spots of each wavelength is decided in accordance with the design of the phase grating.
