The Titan microscope is a image-aberration-corrected scanning transmission electron microscope (STEM/TEM) capable of producing images with .08nm resolution. The Titan 80-200 microscope equipped with a high-brightness Schottky-field emission electron source, a CEOS probe-side aberration corrector, a high-resolution Gatan Imaging Filter and an EDS detector. The instrument is capable of imaging single atoms, and performing nanoscale chemical and structural analysis. Additionally, the system can perform <0.08 nm spatial resolution Z contrast STEM imaging and <0.1 nm spatial resolution HRTEM imaging.  The microscope has two 2048×2048 slow-scan CCD cameras; one is bottom mounted and one is the GIF camera.

Applications range from determining interface structures with sub-Ångstrom resolution and chemistry with single-atom precision to imaging and analyzing nanoparticles in a multiple-target biomacromolecule labeling system.
