Scanning electron microscope - Wikipedia
A scanning electron microscope (SEM) is a type of electron microscope that produces images of a sample by scanning the surface with a focused beam of electrons. The electrons interact with atoms in the sample, producing various signals that contain information about the surface topography and composition of the sample. The electron beam is scanned in a r… See more
Zoom in with the SEM!Have you ever wondered what things look like at the microscopic level? How can we see the details of a mineral, a cell, or a virus? One of the instruments that can help us do that is the scanning electron microscope, or SEM for short.Principles and capacitiesThe signals used by a SEM to produce an image result from interactions of the electron beam with atoms at various depths within the sample. Various types of signals are produced including secondary electrons (SE), reflec… See more

Modern light microscopes are limited by the interaction of visible light waves with an object, called diffraction.www.jove.com/v/5656/scanning-electron-microsco…Scanning electron microscopy is a highly versatile technique used to obtain high-resolution images and detailed surface information of samples. It is a type of electron microscopy that uses a focused beam of electrons to scan the surface of a specimen and generate images at a much greater resolution compared to optical microscopy.www.nanoscience.com/techniques/scanning-electr…In SEM, the electron beam scans the sample in a raster-pattern. Instead of passing through the specimen, electrons get reflected on the surface or even ionize atoms within the sample by liberating electrons. These so-called secondary electrons, as well as the backscattered electrons, can serve as signal to build up the final image.assets.thermofisher.com/TFS-Assets/MSD/Referen…
