A COMPACT COLLINEAR AOTF RAMAN SPECTROMETER

A compact, lightweight, completely packaged, uncooled, fully-automated collinear acousto-optic tunable-filter (AOTF) based spectrometer has been used to measure Raman spectra of three organic energetic material s (NQ, HMX, and TNT) using argon-ion laser excitation. Even though the resolution of the AOTF spectrometer is modest (7.4 cm(-1)) and it was not specifically designed for measuring Raman spectra, it has perform ed impressively. Such an instrument is specially useful for remote sen sing and field measurements. In this paper, we will describe this inst rument, present the measured Raman spectra and their comparison with t he corresponding FT-IR spectra. (C) 1997 Elsevier Science B.V.
