Photoelectron Measuring Device

摘要

To provide a photoelectron measuring device that enables handling of samples in the atmosphere. A photoelectron measuring device that emits ultraviolet light from an ultraviolet light generating source 1 onto a sample S while changing the wavelength and detects the wavelength at which photoelectrons start to be discharged from the sample S, with the section up to an emission outlet 2 being housed in a non-oxygen environment and a sample stand 4 being disposed so that the distance from the emission outlet 2 to the sample S is 7 mm or less.
