Applications
1. Precision Spectrum Analysis
Optical filter sleeve for atomic absorption spectrometers (AAS) and UV spectrophotometers. Filters stray light and selects designated wavelength bands to enhance testing accuracy.
2. Optical Calibration & Light Sources
Reference cell for wavelength calibration in standard light source lamps and optical calibration cavities, utilizing the characteristic absorption spectrum of samarium ions.
3. Laboratory Chemical Analysis
Corrosion-resistant optical reaction sleeve for acidic and alkaline liquid testing, compatible with wet chemical optical measurement setups.
4. Laser Component Integration
Narrow-band light filtering housing for miniature laser inspection modules, isolating interference from ambient light sources.
Advantages over Clear Fused Quartz
Unlike standard clear fused quartz tubes, the 20% samarium doping provides a built-in spectral filtering function while retaining all the superior properties of quartz—high temperature resistance, HF acid resistance, and high purity. This makes it a customized, application-specific tube for precision optical testing and analysis.
