Lanthanum hexaboride (LaB₆) is one of the best thermionic emission materials, because of its low work function and high melting point. DENKA LaB6 Cathode has been highly reputed as an electron source for electron microscopes and electron beam lithograph apparatus.

Single crystal of high purity and quality, grown by floating zone technique, provides stable emission characteristics. Sophisticated machining covers various cone angles and dimensions. It is the only DENKA that can provide hemispherical shape tip.

Electron microscopes (SEM, TEM), apparatus for surface analysis (EPMA, AES), electron beam lithograph apparatus
