AI Technical Summary

Technical Problem

Existing spectrometers can obtain sufficient characteristic spectral signals when detecting a single substance, but their signal dispersion and density are insufficient when detecting multiple substances, which cannot meet the requirements for accurate analysis of multiple substances, and the substance detection range of the spectrometer is limited.

Method used

By setting an adjustable aperture and a non-perpendicular light-gathering path in the light source excitation component of the spectrometer, combined with inert gas dust removal and a Faraday cage structure, dynamic adjustment of the excitation light and electromagnetic interference shielding are achieved, thereby improving the dispersion rate and detection accuracy of the spectral signal.

Benefits of technology

It expands the material detection range of the spectrometer, improves the dispersion rate and signal density of characteristic spectral signals when detecting multiple substances, enhances the ability to accurately analyze multiple substances, and effectively prevents dust pollution and electromagnetic interference.
