Kimball Lanthanum Hexaboride Cathodes for Electron Microscopes 電子顯微鏡用六硼化鑭陰極

 

Description

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.

Kimball Physics ES-423E（長壽命）六硼化鑭（LaB6）陰極是一種高性能、電阻加熱的熱離子電子源。目前，它被用于許多亮度受限的電子光學系統：SEM、TEM、探針、電子光刻系統等。LaB6的亮度至少比鎢大一個數量級，在寬范圍的加速電壓下提供了卓越的分辨率，從而能夠在電子顯微鏡應用中對最精細的細節進行清晰的成像。
