| description | The invention discloses an automatic calibration device and method for a spectrometer, and relates to the technical field of spectrometers, and the method comprises the steps: controlling the action of an incident angle rotating motor according to a specified incident angle after a light beam enters a collimator, and enabling the light beam to enter a grating from the collimator at the specified incident angle; the grating is used for splitting the incident light beam by controlling the action of the grating rotating motor; according to the specified emergence angle, an emergence angle rotating motor is controlled to act according to the specified emergence angle, so that the split light beam enters an imager at the specified emergence angle, and a light source spectrum is obtained at a specified imaging distance; and comparing the light source spectrum with the calibration spectrum, and feeding back and controlling the action of the driver according to the comparison result. Adjustment accuracy is improved, |
