Different Type Of Electron Microscopes

DIFFERENT TYPES OF ELECTRON MICROSCOPES Transmission Electron Microscope (TEM) The TEM is usually referred to as the original electron microscope. It is used to view the thin specimens Through which electron is pass and generate a projection image. It is also used to image the interior of the cell, the structure of protein molecules, and many more. Scanning Electron Microscope (SEM) An SEM electron microscope is just the same as a key copying machine. It provides detailed images of the surface of cells and whole organisms. It is also used for particle counting, size determination, and process control. Scanning Transmission Electron Microscope (STEM) STEM is a combination of TEM and SEM. In fact, most of the TEMS nowadays are hybrid systems that can operate either on TEM and STEM mode. It is used to determine the crystallographic structure of the material on a fine scale. Reflection Electron Microscope (REM) REM is a combination of imaging, spectroscopy techniques, diffraction, crystal structure, and composition of the surface of single crystals. It is used for the surface reconstruction and phase transformations as well as for the growth of films. Cryo-Electron Microscopy Cryo-EM is a structural biological method that is used to determine the 3D structure of biomacromolecules. It is used for the leaf specimens, for edge observation and fracture, and used particularly for the too-small specimen. For More Information Visit: nanoimages.com
