Electron Microscope Emitter
DENKA LaB6 Cathode
Use
Electron microscopes (SEM, TEM), apparatus for surface analysis (EPMA, AES), electron beam lithograph apparatus.
Features
One of the best thermionic emission materials, because of its low work function and high melting point.
Highly reputed as an electron source for electron microscopes and electron beam lithograph apparatus.
Single crystals of high purity and quality, grown by floating zone technique, provide stable emission.
Sophisticated machining covers various cone angles and dimensions.
