Nion makes world-leading aberration-corrected STEMs. They excel in spatial resolution (1.07 Å at 30 keV), EELS resolution (<5 meV), efficient EDXS (>0.7 sr solid angle), and UHV at the sample. Powerful, easy-to-use, open-source microscope control software, Nion Swift, puts the power of the Python community in the hands of the microscope user.
