  • High-resolution (lattice) imaging with <0.1 nm information limit
  • <100, <80, and <60 pm STEM resolution at 60, 200, and 300 kV, respectively
  • Dedicated Lorentz lens for TEM mode imaging of magnetic domains; STEM imaging of magnetic domains with ~1 nm resolution enabled by Cs probe-correction and DPC-STEM imaging
  • Super-X windowless SDD energy dispersive spectroscopy system with 0.7 sr solid angle of collection
  • Fully automated TEM, STEM, and STEM-EDS tomography data acquisition
  • Inspect 3D reconstruction and Avizo visualization software for processing and analysis of tomography data (separate onsite workstation)
  • EMPAD 128x128 direct electron detector; single electron sensitivity with 30 bit dynamic range; diffraction pattern recorded at every pixel in a map (4D-STEM) up to 512x512 resolution
