The FEI Titan 80-300 scanning transmission electron microscope (STEM) is an advanced analytical field emission scanning transmission electron microscope capable of atomic-level imaging and analysis on a wide range of materials and nanostructures. The Titan is equipped with an electron energy loss spectrometer and an x-ray energy dispersive spectrometer for elemental and chemical analysis of materials at high spatial resolution. The microscope system includes a scanning module and a high angle annular dark field detector for scanning transmission electron microscopy (STEM) and for chemical analysis of very small volumes.
