JEOL-GrandARM

Brief description

The GrandARM is a high-end electron microscope for experienced users. It has a cold field emission gun (Cold FEG) and a Cs corrector that compensates for higher order aberrations. These enable atomic-resolution imaging at 300 kV as well as at 80 kV accelerating voltage.


Technical details

Camera / detectors:

  • Gatan 1View (16 M pixel CMOS Camera, 25 fps @ 4k×4k)
