Cathodes & Filaments
Utilized to generate the electrons used in scanning electron microscopes, cathodes and filaments for SEM are electron-emitting materials available in a variety of types, each with its own characteristics. A Lanthanum Hexaboride (LaB6) cathode or LaB6 filament, for example, has a shorter lifespan than a cerium hexaboride (CeB6) cathode, but both create high-brightness electron beams. Both materials also create stable emission beams over time, which contributes to consistent quality for SEM imaging.
