The JEM-2200FS, a state-of-the art analytical electron microscope, is equipped with a 200kV field emission gun (FEG) and the in-column energy filter (Omega filter) that allows a zero-loss image, where inelastic electrons is eliminated, resulting in clear images with high contrast. And energy-filtered images forming with electrons at low loss or core loss energy provide chemical state or elemental information of a sample. Also, spectroscopy for elemental analysis and chemical analysis of specimens is available.
