Abstract
Disclosed is a spectroscopic system having a fiber-optic probe for simultaneous IR and Raman measurement. The probe includes a single strand of optical fiber, such as sapphire which is suitable for IR absorption measurements as far as 4 μm and Raman excitation at wavelengths as short as 300 nm. The probe is immersed in the sample and functions in the evanescent wave mode for both IR absorption and Raman scattering measurements. The sensing system makes possible the synergistic, and simultaneous, analysis of both IR and Raman data in an integrated device.
