FlexiSpec® product line includes the high sensitivity Raman fiber optic probe to be used with any Raman spectrometer.
Available in two options – multi-wavelength excitation (630-785 nm) and single-wavelength excitation (532 and 785 nm), these fiber probes have a bifurcated design, connecting the probe to both a laser and a spectrometer. Our Raman probe allows to analyze spectra in fingerprint (FP, 800-1800 cm-1) and high wavenumber (HWVN, 2800-3800 cm-1) spectral ranges using different lasers.
FlexiSpec® Raman fiber optic probes are compatible with process-interfaces to be cleanable and to enable reaction monitoring in lab, pilot plant and run full automated process control.
