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.

Picture of Lanthanum and Cerium Hexaboride (LaB6 and CeB6) Cathodes

Lanthanum and Cerium Hexaboride (LaB6 and CeB6) Cathodes

Greater brightness from low work function yielding higher currents at lower temps than tungsten. Ideal for small spot sizes in SEM, TEM, surface analysis and metrology.
