Realizing the longevity of filaments! Introducing Gakuseki Electric's coating technology.
Yakeshi Electric has been working on the development of coating technology in response to customer feedback, such as the desire to suppress certain properties while not allowing changes in material or shape. By coating the filament, which serves as the electron source, with materials that have a low work function, it becomes possible to efficiently emit electrons, ultimately leading to an extended lifespan of the filament. If you have any concerns, whether regarding medical X-rays, non-destructive testing equipment, or mass spectrometry devices, please feel free to consult with us.
