Electron Microscope: Transmission, Scanning

EMSL's aberration-corrected Titan 80-300™ scanning/transmission electron microscope (S/TEM) provides high-resolution imaging with sub-angstrom resolution and spectroscopic capabilities. This state-of-the-art instrument is equipped with a Schottky field-emission electron source, an electron gun monochromator, a CEOS hexapole spherical aberration corrector for the probe-forming lens, a high-angle annular dark-field (HAADF) detector, an X-Ray Spectrometer (EDS) and a high-resolution GIF. The selection of electron energy between 80kV and 300kV enables optimized imaging for a variety of materials, including electron beam sensitive materials.
