emission spectrum

Plot of the emitted spectral radiant power (spectral radiant exitance) or of the emitted spectral photon irradiance (spectral photon exitance) against a quantity related to photon energy, such as frequency, $ν$ , wavenumber, $σ$ , or wavelength, $λ$ . When corrected for wavelength-dependent variations in the equipment response, it is called a corrected emission spectrum.
