The calibration light from the light inlet 13 is adjusted to coincide with the light irradiated on the work surface by the light source of the laser processing apparatus itself. The specific adjusting mode is as follows: step one, rotating the rotating base 2 in a small range, the deflection angle of the spectroscope 4 in the left-right direction can be adjusted, and when the calibration light is overlapped with the target in one direction, the rotating base 2 is fixed by the locking screw 8. And step two, adjusting the screwing depth of the two adjusting screws 5, and adjusting the inclination angle of the adjusting seat 3, so as to adjust the deflection angle of the spectroscope 4 in the front-rear direction, and when the calibration light is also overlapped with the target in the other direction perpendicular to the step one, the calibration of the light path is completed.
