The Nova 200 is the KNI's highest-resolution analytical scanning electron microscope (SEM), equipped with an immersion-lens for imaging sub-10 nm features and both energy dispersive spectroscopy (EDS) and wavelength dispersive spectroscopy (WDS) detectors for compositional analysis. It is also outfitted with a gallium focused ion beam (Ga-FIB) column, which is currently not operational because the Nova 600 NanoLab and ORION NanoFab together meet the KNI's Ga-FIB demand; gallium could be reactivated on the Nova 200 the future. See a full list of training and educational resources for this instrument below.
