Scanning Electron Microscope (SEM)

Scanning Electron Microscope (SEM)

The first Scanning Electron Microscope was initially made by Mafred von Ardenne in 1937 with an aim to surpass the transmission electron Microscope. He used high-resolution power to scan a small raster using a beam of electrons that were focused on the raster. He also aimed at reducing the problems of chromatic aberrations images produced … Read more Scanning Electron Microscope (SEM)
