(SLIDE SHOW) 1064 nm Raman spectrometer offerings grow

Handheld and miniature spectrometer designs continue to evolve as optical components and detectors improve in performance while shrinking in size, enabling in-the-field applications to emerge from the constraints of the laboratory. Although the Raman scattering signal is much weaker than the Rayleigh-scattered light, Raman spectroscopy at wavelengths spanning the ultraviolet to the near-infrared can provide more detailed and specific information on vibrational modes of the sample, making it able to identify more chemical components and materials than standard spectroscopy. By moving to longer excitation wavelengths like 1064 nm, fluorescence interference signals are better eliminated and dynamic range of the measurement is increased.
