Abstract

Abstract: A spectroscopic technique that uses the scattering of photons for analysis of the chemical structure is called Raman spectroscopy. Raman spectrometers used in labs are typically large, so they are not applicable for use in fieldwork, and commercially portable Raman spectrometers are expensive. So, we developed a compact Raman spectrometer for field usage that consists of only the necessary optical components to make the compact system affordable for carrying in the field. Reduce fluorescence noise in the system by using the Vancouver Raman algorithm, which is based on polynomial fitting to achieve a quality Raman spectrum and can correctly identify the chemical structure in the sample. There are four samples: paracetamol, naphthalene, acetone, and toluene. The Raman spectra of the measured samples were compared with the database. The results are close to the commercial Raman spectrometer, which indicates our proposed compact Raman spectrometer is reliable.
