What is a Raman spectrometer?

In Raman spectroscopy, the chemical structure of a substance can be investigated from the scattered light of the light shining on the substance, so the Raman spectrometer is a device that utilizes this property. Scattered light contains light of various wavelengths, the same wavelength as the incident light is called Rayleigh scattered light, and the different wavelength is called Raman scattered light. The Raman spectroscope consists of a spectroscope that uses a laser light source and a diffraction grating, and a detector with a favorable sensitivity for detecting weak Raman scattered light. The structure of most substances, whether gas, liquid or solid, can be measured without pretreatment.
Raman spectrometers are used to study the chemical structure of matter Raman spectroscopy has a wide variety of applications in the fields of batteries, displays, food science, medical and pharmaceutical fields, as a method for analyzing its chemical and molecular structures regardless of whether it is an organic or inorganic material. In food science, it is possible to perform quantitative analysis of biomolecules such as proteins and diffusion contained in food. For pharmaceuticals, Raman spectroscopy can be used to study the crystal structure, which can be used to determine biological utility. It can also be used to monitor the constituent materials of electrodes when charging and discharging batteries.
