Cleaned tungsten wire has diverse applications in optical instruments, primarily including the following:
- High-Brightness Light Source: In optical microscopes, projectors, or spectrometers, cleaned tungsten wire is used as the filament, heated to incandescence to provide a high-brightness, stable light source. Its high melting point and smooth surface ensure uniform light output, suitable for high-precision optical imaging or analysis.
- Micro-Support Structures: With its high strength and ultra-fine diameter (down to a few microns), cleaned tungsten wire is used in precision mechanical components of optical instruments, such as grating positioning, lens fine-tuning mechanisms, or laser alignment devices, meeting stringent precision requirements.
- Electron Beam Source: In certain optical analysis systems (such as those combined with scanning electron microscopes), cleaned tungsten wire serves as a thermionic cathode to emit electron beams for photoelectric detection or imaging. It offers high thermal emission efficiency and stable electron beam performance.
- Calibration Components: The dimensional stability of cleaned tungsten wire makes it suitable as a standard component in optical instrument calibration, such as wavelength calibration or focal length adjustment.
