Scanning Electron Microscope SEM For High-Resolution Imaging

Scanning Electron Microscopes (SEM) are advanced imaging instruments that use a focused beam of electrons to scan the surface of a specimen, producing highly detailed, three-dimensional images. SEM provides topographical, morphological, and compositional information with high resolution and depth of field. SEM is widely used in materials science, electronics, biology, geology, and nanotechnology for surface analysis, failure investigation, and microstructural characterization. Specimens often require coating with a conductive material to enhance imaging quality.
