Abstract: Disclosed herein are Raman spectrographic systems and methods of assembling Raman spectrographic systems. The Raman spectrographic system includes a light source to emit ultraviolet incident light into a waveguide, and an interaction region traversed by the waveguide and that holds a sample to be identified. A spectrometer detects Raman scatter from an output light in the waveguide emerging from the interaction region following interaction between the incident light and the sample and output a spectral response. The spectrometer includes an array of detectors. Each detector of the array of detectors is a silicon carbide (SiC) detector to obtain information that includes an intensity corresponding with a wavelength of the Raman scatter. A controller identifies the sample based on the spectral response from the array of detectors.
