Abstract
The need to rapidly detect and identify traces of hazardous materials motivated the development of a modular, compact Raman spectrometer. Its performance for point and proximal detection was tested, while acquiring Raman spectra and Raman spectral maps of different compounds. This system offers high sensitivity and following its combination with photo-guided sampling, its capability for Raman mapping of particles is improved, being faster than raster scanning. The detection capabilities of the spectrometer make it a potential candidate for replacing existing Raman microscopes and for applications to detection of other compounds and under other situations.
