Abstract: Raman spectroscopy offers unique advantages for analytical applications. In this study, a teaching Raman spectrometer was successfully developed to enhance students’ comprehensive abilities in the field of chemical measurement science. The instrument is characterized by its compact size, low cost, and modular design, allowing for easy disassembly and reassembly. The self-developed components were designed for modular assembly, and the instrument was used in laboratory teaching to demonstrate Raman spectroscopy applications in both scientific and engaging ways. Through understanding the principles of Raman spectroscopy and mastering testing techniques, students can improve their practical skills, problem-solving abilities, and innovative thinking. This experiment offers students a deeper insight into the internal structure, instrument design, and performance optimization of scientific instruments, and is expected to stimulate their enthusiasm for instrument development.

Key words: Teaching Raman spectrometer, Modular assembly, Instrument debugging, Raman detection, Educational application
