A spectrometer is a precision instrument used for compositional analysis based on the absorption, emission, or scattering properties of substances with light. By resolving composite light into monochromatic components of varying wavelengths, it generates characteristic spectra to enable qualitative and quantitative identification of material compositions. Spectrometers find extensive applications in fields such as material characterization, environmental monitoring, and industrial inspection.

Barium tungsten electrodes, owing to their unique physicochemical properties, demonstrate extensive application potential in plasma generation devices. As a core electron emission source, their low work function and high current density characteristics provide critical support for the diversified applications of plasma technology.

Barium tungsten electrode may be used as an efficient electron emission source in night vision equipment, and the photoelectric conversion efficiency is improved by combining the low work function of barium with the stability of tungsten. Its application is mostly seen in traditional or special night vision equipment, especially in scenes that require high current density or specific infrared response.

The barium tungsten electrode used in electropulse sterilization equipment is a high-performance electrode material. Its core advantages lie in the combination of tungsten's high melting point, corrosion resistance, and barium's low work function characteristics.
