Today, spectroscopic methods have attracted the attention of many researchers and industrialists for the identification and characterization of materials due to their many advantages over other analysis methods. Raman spectroscopy is one of the types of vibrational spectroscopy methods that are used in many fields such as biology, medicine, identification of drugs, petrology, 2D materials, semiconductors, protein materials, food, etc. Raman spectroscopy is a widely used, fast, accurate, and non-destructive method. Raman spectra contain valuable information about the molecular structure of materials. Raman microspectrophotometers, in addition to recording the Raman spectra of the micrometric points of the samples, can provide transmission and reflection imaging of the desired points.
