PROBLEM TO BE SOLVED: To provide an emission spectrophotometer for easily performing analysis at appropriate analysis accuracy and analysis sensitivity according to the type, state, and analysis purpose of a sample.SOLUTION: The emission spectrophotometer excites the solid sample S to emit light by discharge, wavelength-disperses the emission light with a spectrometer 20, and detects light of a specific wavelength. The emission spectrophotometer includes a sample holding means for holding the solid sample S, a condenser lens 14 that is arranged between the sample holding means and the spectrometer 20, condenses a part of the emission light, and introduces it to the spectrometer 20, a light shielding mask 15 arranged ahead of the condenser lens 14, and a mask driving means 16 for altering the angle formed by a surface to be analyzed of the solid sample S and the optical axis of the emission light entering the spectrometer 20 by moving the light shielding mask 15. |
