Electron-spectrum analyzer VG Scienta

General description :

With features as a 0.1 mm entrance slit and 1 eV pass energy the R4000WAL-0.1 spectrometer claims the best energy resolution on the market. This wide angle acceptance analyzer is fully equipped for XPS, UPS, and ARPES studies with lens tables for overview and high resolution angular and transmission modes. Kinetic energies from 0.5 eV - 1500 eV are measured with a selection of slits and wide range of pass energies from 1-200.
