The miniRaman Spectrometer is an innovative, miniaturized Raman spectrometer equipped with a patented, integrated reference channel. This innovative technology ensures automatic calibration by correcting for laser wavelength drift. The system continuously adjusts the Raman shift and intensity of the sample spectrum, delivering fast, accurate, and reliable results. These advanced features make the miniRaman spectrometer an ideal solution for material identification and precise quantitative measurements.
