Abstract

The invention discloses a raman spectrum detection method. An excitation light source system forms exciting light, exciting light can form parallel light after passing through a beam expanding device in the excitation light source system, horizontal incident light entering the vertical side of a raman optical filter unit horizontally can be formed, then vertical emergent light going out vertically from a horizontal side perpendicular to the vertical side of the raman optical filter unit is formed, light spots with high irradiance and focused at the position of a sample are formed by a microobjective with high numerical aperture, therefore, raman scattering is formed, a raman signal enters a monochromator system to be subjected to light splitting treatment after being subjected to filtering of the raman optical filter unit, the follow-up focusing treatment and the imaging regulation treatment, then the raman signal is received by a single-photon counter, and the wavelength of the raman signal can be determined by the monochromator system and the single-photon counter together. According to the raman spectrum detection method, high-intensity exciting light can be formed by the raman optical filter unit through focusing and can excite the sample to form the raman signal, and the method has high speed and high accuracy, and can detect substances with weak raman signals, such as raman peak of water.

Description

technical field [0001] The invention relates to the field of spectrum detection, in particular to a Raman spectrum detection method. Background technique [0002] Raman spectroscopy is a kind of scattering spectrum, which was discovered by Indian physicist Chandrasekhara Venkata Raman in 1928 and won the Nobel Prize in Physics in 1930 for it. Raman spectroscopy has been widely used as a means of analyzing and testing the molecular structure of substances. Especially after the first laser came out in 1960, the introduction of laser light sources, the improvement of weak signal detection technology and the application of computers have made Raman spectroscopy analysis Great progress has been made in many application areas. At present, Raman spectroscopy has been widely used in petroleum, food, agriculture and animal husbandry, polymers, pharmaceuticals, biology, medicine and other fields. [0003] The working principle of the Raman spectrometer is as follows: [0004] When ...
