Calibration of a spectrometer built at the Professional School of Physics - UNSA

The present paper presents a methodology to calibrate a spectrometer. The methodology to calibrate the spectrometer was direct comparison using a calibrated spectrometer, a mercury lamp and two lasers, a red and a green one, and the solar spectrum measured by a calibrated spectrometer. As a result of the calibration, a methodology to correct the errors of the spectrometer was identified and the adjustment of the spectrometer was achieved successfully by reducing the errors in the position of the peaks to values of less than 2 nm and values of the intensity have been corrected to achieve errors of less than 11% compared with the measurements made by the calibrated spectrometer.
