Template titel

template tekst – Scanning Electron Microscopy (SEM) is a method where a focussed beam of electrons is scanned over the sample surface. The recorded signal is scanned onto a screen or into a digital image. A conventional SEM requires a high vacuum sample chamber, where the electron bundle interacts with the sample. Low Vacuum and environmental SEM instruments are available as well.
