Nanoscience: Scanning Electron Microscopy

FEI Inspect S50 Scanning Electron Microscope

Scanning Electron Microscopy (SEM) exploits the smaill wavelength of an electron to produce high resolution images with magnifcations exceeding 100 000X. This image can be obtained by measuring either the backscattered (i.e. reflected) incident electrons or secondary electrons ejected from the sample surface.
