Backscattered electron detector

A backscattered electron detector is a device used in electron microscopes to detect high-energy electrons that are reflected back from a specimen’s surface. When the microscope’s electron beam hits a sample, some electrons bounce back and carry information about the composition and density of the material. The detector captures these backscattered electrons, allowing scientists to create detailed images and analyze the sample’s structure and chemical makeup. This technique provides valuable contrast and insights, especially useful in studying material properties at very small scales.
