Valid spectral range(s)
Min - Max ($eV$) Sampling ($eV$) Resolution ($eV$) Position accuracy ($eV$) Absorption edge
#1 11447.5 - 12414.3 0.593 $Pt$ (L3: 11.5637 $keV$)
Comments
The resolution in the above table is the resolution given by the monochromator. The energy was calibrated by measuring the absorption edge of a reference: Pt metallic foil (first maximum of the derivative set at 11564 eV).
