415–957nm LIBS Spectrometer
The 415-957 nm LIBS spectrometer is a compact, high-resolution spectrometer designed for laser-induced breakdown spectroscopy (LIBS) and visible-to-near-infrared spectral analysis. It covers the wavelength range of 415-957 nm and achieves a typical resolution of 0.4-0.6 nm. The instrument employs a high-efficiency transmission grating and an MGM optical structure, offering high resolution, low stray light, low thermal drift, and a small footprint. It supports SMA905 fibre input and SPI/USB data interfaces, enabling easy integration into portable and OEM inspection systems. It is suitable for metal and alloy composition analysis, mineral detection, elemental identification, plasma emission spectroscopy, and scientific spectroscopic studies.
