Scanning Electron Microscopy Study of Hair Shaft Damage

WebScanning electron microscopes (SEMs) use an electron beam to image samples with a resolution down to the nanometer scale. The electrons are emitted from a filament and collimated into a beam in the electron source. The beam is then focused on the sample surface by a set of lenses in the electron column.
