Optical Microscope

The JEM-2200FS, a cutting-edge analytical electron microscope, is equipped with a 200kV field emission gun (FEG) and an in-column energy filter (Omega filter) that enables a zero-loss image. This eliminates inelastic electrons, resulting in clear images with high contrast. The chemical state or elemental information of a sample is provided by energy-filtered images that are formed with electrons at low loss or core loss energy. Additionally, spectroscopy is accessible for the chemical and elemental analysis of specimens.



Omega filter (in-column energy filter)



The in-column energy filter allows for the acquisition of electron energy loss spectra and energy-filtered images. The filtered images are distortion-free due to the filter's optimal design.
