Feature	Benefit
< 5 meV energy resolution at 30 kV (< 6 meV at 60 kV)	Resolve fine differences in EELS spectral edges
Large energy range of up to 2 keV at 200 kV	Collect all elements in one EELS spectrum
Correction of all fifth-order axial aberrations	Larger probe angles, higher beam current
Every operation can be performed remotely	Remote operation with no local assistance
Friction-free, centro-symmetric sample stage	Ultra-precise sample motion, freedom from drift
Double tilt sample holder using ball bearings	Backlash-free, ultra-precise tilting
Fast electrostatic beam blanker	Avoids sample damage when not collecting data
5th-order-corrected EELS optics	>50 mr acceptance semi-angles, more efficient analysis
Microscope column is entirely ion-pumped	Minimizes sample contamination and etching
Column uses only metal vacuum seals	Sample vacuum typically <1x10^-9 torr
Whole column bakeable to 140°C	Minimizes sensitivity to stray AC fields
Double μ-metal shielding of entire column	Column can be reconfigured after installation
Self-diagnosing electronics	Rapid remote servicing
