The aberration-corrected JEM-2200FS, a state-of-the-art analytical electron microscope, is equipped with a 200kV field emission gun (FEG), a CEOS probe Cs-corrector, and an in-column energy filter (Omega Filter) that allows elemental analysis and chemical analysis of specimens. It is also equipped with an Energy Dispersive X-ray Spectrometer (EDS) and a CCD-camera. With an available small probe size of ~0.1 nm, atomic level high-resolution high-angle annular dark-field (Z-contrast) images, and high resolution EELS spectrum imaging can be obtained. With the low background Be specimen holder, large (50mm2) detector area, and the hard X-ray aperture, high-quality EDS analysis and mapping is available.
