The Kimball Physics ES-423E (Extended Life) Lanthanum Hexaboride (LaB6) Cathode is a high performance, resistively heated, thermionic electron source. It is currently employed in many brightness-limited electron optical systems: SEM’s, TEM’s, probes, electron lithography systems, and more. With brightness at least an order of magnitude greater than tungsten, LaB6 provides superior resolution in a wide range of acceleration voltages to enable clear imaging of the finest details in electron microscopy applications.
