The Titan Themis3 300 S/TEM is one of the most advanced electron microscopy platform providing high-resolution imaging with high performance analytical investigation capabilities at atomic level. It combines proven spherical aberration (Cs) –correctors to both image and probe forming optic system resulting in resolution limits below 1 Å for both modes for all high tensions between 60 kV and 300 kV. The high brightness electron gun (X-FEG) equipped with a monochromator to improve the energy resolution in combination with a high-sensitivity SDD X-ray spectrometer (Super-X) and a high-resolution post-column energy filter (GIF Quantum) creates a high performance analytical instrument perfectly suited for the nanoanalytical characterization of all kinds of materials and devices. Energy filtered TEM (EFTEM) imaging, high-resolution electron energy-loss spectroscopy (EELS) as well as energy-dispersive X-ray spectroscopy (EDXS) yield chemical, elemental as well as bonding information even down to the atomic scale.
