Field Emission Scanning Electron Microscopy

Scanning Electron Microscopy

Key benefits

Description of our FESEM scope

A scanning electron microscope creates high resolution, three dimensional images of a sample’s surface. The sample, often gold-coated for electroconductivity, is bombarded with a focused beam of electrons which liberates secondary electrons from the sample’s surface. A detector in the microscope systematically “counts” these electrons, recording data on their origin and emission intensity which can then be assembled into a high contrast, high resolution image. Our laboratory features an Hitachi S4500 field emission scanning electron microscope with a Bruker Image Acquisition system which is used to generate high quality digital images from the microscope.
