Abstract

The invention provides a Raman spectrum detection optical path device. The Raman spectrum detection optical path device includes a light source assembly, which is used to emit excitation light on the object to be detected and generate a Raman spectrum; a lens, which is used to collect the Raman spectrum generated when the light source assembly is irradiated on the object to be detected, and convert the resulting The Raman spectrum is focused into a light spot; an optical fiber, one end of the optical fiber is distributed in a cylindrical shape, and the other end is distributed in a flat shape. The cylindrical end of the optical fiber is used to collect the light spot focused by the lens, and the flat end of the optical fiber is It is used to arrange the light spots into narrow strips of light and output them; grating and photodetector. The invention also provides a detection method of the Raman spectrum detection optical path device. The Raman spectrum detection optical path device and detection method of the present invention design one end of the optical fiber into a cylindrical shape and the other end into a flat shape, thereby arranging the focused light spots into narrow strips of light to achieve high-magnification focusing and improve detection of weak Raman Spectral detection capabilities.

Description

technical field [0001] The invention relates to Raman spectrum detection equipment, in particular to a Raman spectrum detection optical path device. Background technique [0002] When the light is irradiated on the material, elastic scattering and inelastic scattering occur. The scattered light of elastic scattering has the same wavelength as the excitation light, and the scattered light of inelastic scattering has components with longer and shorter wavelengths than the excitation light, collectively called Raman scattering. , the corresponding light is called Raman spectrum. Raman spectroscopy belongs to the vibrational spectrum of molecules. Therefore, the substance and composition of the tested substance can be known by detecting the Raman spectrum excited by the substance. [0003] At present, Raman spectroscopy is often used in the field of medicine, especially the analysis of pharmaceutical ingredients. Therefore, Raman spectroscopy detectors are widely used by resear...
