Abstract
This paper provides comprehensive evidence for the performance of a highly sensitive NIR Raman spectrometer that is based on a single monochromator, a holographic edge filter, and a germanium photodiode array and that employs the scanning multichannel technique. In terms of signal-to-noise ratio, resolution, band intensities, and band shape accuracy, the spectra presented are the best reported so far with the use of a multichannel NIR Raman spectrometer. We believe that the design proposed here can yield data at least as good as FT-Raman data, for any given sample.
