Fison Handheld Raman Spectrometer uses a 1064 nm laser excitation wavelength, which allows scanning of fluorescent materials, and records Raman shift across a 200 to 2500 cm?¹ spectral range. As a handheld raman spectroscopy device, it feeds real-time spectral acquisition to the identification algorithms, while compact design and precision optics maintain sensitivity and stability, and the software handles calibration and data interpretation. It identifies the molecular composition of samples from the Raman spectra it records.
