Description
This Hitachi SEM tungsten filament is a high-quality replacement electron source designed for use in Hitachi scanning electron microscopes. Tungsten filaments remain one of the most widely used electron emitters in conventional SEM systems due to their robustness, cost efficiency, and stable emission characteristics.
Each filament features a precision-manufactured tungsten wire mounted on a ceramic and metal base, ensuring consistent geometry and reliable electrical contact. The filament is suitable for standard thermionic emission SEM designs and provides predictable beam stability after proper alignment and conditioning.
This product is ideal for laboratories, research institutes, universities, and industrial inspection facilities that require dependable SEM consumables for routine maintenance or emergency replacement. All units are visually inspected to ensure intact filaments, clean mounting surfaces, and proper pin alignment before shipment.
Compared with field emission sources, tungsten filaments offer easier handling, lower system requirements, and reduced operating costs, making them an excellent choice for many Hitachi SEM models still in active service worldwide.
