LIBS System
In a LIBS measurement system, the spectrometer generally sends a synchronized trigger to the laser, which focuses a pulse onto the sample. Within a specified time, collection optics direct the returning light into a multichannel spectrometer, such as the Jianzhi Technology SR75C fiber-spectrometer series. A computer processes the collected data, displays spectra and determines elemental identities and concentrations. LIBS relies on laser-material interaction: high-energy-density pulses rapidly excite the sample surface to form plasma, whose spectrum provides sample information. The process is very fast and suitable for rapid on-site analysis.
