A spectrometer system and spectroscopic analysis method

Abstract

The embodiment of the invention discloses a spectrometer system and a spectrum detection and analysis method. The spectrometer system includes: a lighting device and a detection device. The lighting device includes a light splitting structure and a light filtering structure. There is a test channel between the lighting device and the detection device; In terms of optical structure; the filter structure is used to filter the stray light in the monochromatic light and then emit the monochromatic light in the target wavelength range, pass the emitted monochromatic light through the test object in the test channel, and then irradiate it on the detection device; The device is used to receive the optical signal after the monochromatic light in the target wavelength range reacts with the object to be measured, and the optical signal is an optical signal used for spectral analysis of the object to be measured. The embodiment of the present invention solves the problem that the detection effect of the spectrometer is affected by the phenomenon of cascading and cross-coloring of the spectrum when the traditional spectrometer is used for light splitting, and the problem of the deflection angle in the traditional spectrometer.

Description

technical field [0001] This application relates to but not limited to the field of optoelectronic technology, especially a spectrometer system and a spectroscopic detection and analysis method. Background technique [0002] With the development of optoelectronic technology, spectral analysis using photoelectric signals of spectrometers has become an implementation scheme for material detection. [0003] The core of the spectrometer is the spectral spectroscopic system. According to different spectroscopic principles, the spectroscopic spectroscopic system can be divided into dispersion type and modulation type. The dispersion type spectroscopic system includes prisms, gratings, interferometers, etc., and the modulated spectrometer system includes Fourier transform spectrometers, for example. . In the dispersive spectroscopic system, the prism spectroscopic system has low dispersion rate and poor spectroscopic performance; the grating spectroscopic system can realize wide sp...
