What is electron microscopy?
Electron microscope uses a beam of electrons as a source of illumination. They use electron optics to control the electron beam, for instance focusing them to produce magnified images or electron diffraction patterns. As the wavelength of an electron can be up to 100,000 times smaller than that of visible light, electron microscopes have a much higher resolution of about 0.1 nm (Wikipedia)

SEM is useful for materials science and for industrial manufacturing and can be used to image materials ranging e.g. from nano- and microparticles, catalysts, and nanodevices to bulk magnetic samples and insulators such as polymers. SEM can also be used in biological sciences for imaging e.g. fixed cells or tissue blocks at high magnifications. Our FE-SEM has also broad analytical extensions, such as STEM (Scanning Transmission Electron Microscopy) detector for TEM grid imaging, Cathodoluminescence detector (CLD) and EDS detector for elemental analysis.
