Abstract

The invention discloses a portable Raman spectrometer. The spectrometer comprises a main system which comprises a laser, a laser probe, an analysis module and a first imaging module, wherein the laser, the laser probe, the analysis module and the first imaging module are sequentially connected; and a micro-area system which comprises an optical system of a microscope, wherein the optical system of the microscope which is connected with the laser is also connected with the analysis module, and the lower part of the optical system of the microscope is provided with a sample testboard which can bear a slide glass. In the invention, the portable Raman spectrometer allows the demand of a sample amount to be substantially reduced by means of the micro-area system and allows the routine analysisof a large sample amount to be carried out when only the main system is used for analysis. The portable Raman spectrometer which is a supplement to existing portable Raman spectrometers allows the development of the portable Raman spectrometers to be promoted.

Description

technical field [0001] The invention relates to an analysis instrument, in particular to a portable Raman spectrometer. Background technique [0002] Raman scattering is a kind of light scattering phenomenon. When the incident photon of a monochromatic beam interacts with molecules, elastic collisions and inelastic collisions can occur. During the elastic collision process, there is no energy exchange between photons and molecules, and photons only change motion. direction without changing frequency, this scattering process is called Rayleigh scattering. In the process of inelastic collision, energy exchange occurs between the photon and the molecule. The photon not only changes the direction of motion, but also transfers part of the energy of the photon to the molecule, or transfers the vibration and rotation energy of the molecule to the photon, thus changing the frequency of the photon. , this scattering process is called Raman scattering. The number of Raman spectral l...
