| Abstract: | Taking PG4000 portable grating spectrometer as an example,the complete calibration process of grating spectrometer was presented,including the suppression of higher order diffraction,wavelength calibration and intensity calibration.After calibration,the emission spectrum of argon glow plasma was measured,which agreed well with the standard spectrum of argon from NIST. |
