WebFloor model SEMs offer the flexibility and versatility to meet a wide range of academic and industrial needs: support for large and heavy samples, a very wide range of accessories, excellent imaging quality for the most challenging materials or the smallest details, and dynamic experimentation. Scanning electron microscopes (SEMs) have become powerful and versatile tools for material characterization, especially in recent years, as the size of materials used in various applications continues to shrink. Electron microscopes use electrons for imaging in a similar way that light microscopes use visible light. See more In scanning electron microscopy, the electron beam scans the sample in a raster pattern. First, electrons are generated at the top of the column by the electron source. … See more In a similar way to optical microscopes, lenses are used to control the path of the electrons. Because electrons cannot pass through glass, the lenses that are used are electromagnetic. They simply consist … See more BSEs and SEs are detected by different types of detectors. For the detection of BSEs, solid state detectors are placed above the sample, … See more The interaction of electrons within a sample can generate many different types of electrons, photons, or irradiations. In the case of an SEM, the two types of electrons used for imaging are backscattered (BSE) and … See more WebSEMs, Benchtop SEM’s and Tabletop SEM’s are used in materials science for research, quality control and failure analysis.
