The Hitachi S-4700 is a field emission scanning electron microscope (FE-SEM), capable of high resolution imaging and specimen topography study from nanometers to millimeters. It uses an electron beam to image the surface of solid materials. Under optimal working conditions, it can magnify images upwards of 500,000 times and resolve features to 2 nanometers. Electron source is a cold FE gun producing high brightness with little energy spread.
