[Comparisons of two ultraviolet-vacuum ultraviolet radiation scales].

The ultraviolet-vacuum ultraviolet emission standards including high temperature argon wall-stabilized arc and synchrotron radiation were introduced. The spectral radiometric characteristics of an argon wall-stabilized arc and a deuterium lamp calibrated by synchrotron radiations were studied as ultraviolet-vacuum ultraviolet radiation scales. With the spectroradiometris system of high precision established by us, the comparison of scales between the argon wall-stabilized arc and the synchrotron radiations in the 165-300 nm range has shown agreement to within +/- 5%.
