They can image a wide range of materials and biological samples with high magnification, resolution, and depth of field, thereby revealing surface structure and chemical composition. Industries like ...
Unlike optical microscopy, SEM does not rely on light waves but instead uses a beam of electrons to interact with materials, enabling magnifications up to 300,000× and resolutions approaching 1 nm. 1 ...
TEM works by transmitting a beam of electrons through an ultra-thin specimen. As the electrons interact with the specimen, they are scattered or transmitted, producing an image that is magnified and ...
