The present invention relates to a continuous wave band excitation light source device, the continuous wave band excitation light source device includes an excitation light source array, which includes a plurality of excitation light sources for emitting excitation light; an optical filter group, which includes a plurality of optical filters, multiple Each excitation light passes through the filter to form excitation light of different bands; multiple optical fiber units transmit the excitation light passing through each filter to excite the chip to be detected; the control circuit is used to control the multiple excitation light sources in the array. Excitation light source for logic control. Through the continuous-band excitation light source device provided by the present invention, when switching the optical path, there is no need to perform mechanical rotation, and there is no need to re-calibrate the optical path. It is only necessary to control the different excitation light sources and the intensity of the light source, which significantly improves the test accuracy and convenience. Integration with light source devices.
Description
technical field [0001] The invention relates to the technical field of fluorescence analysis, in particular to a continuous wave band excitation light source device. Background technique [0002] In recent years, fluorescence analysis technology has been widely used in scientific research and production. Fluorescence analysis technology refers to that a continuous-band excitation light source device of a certain wavelength is irradiated on the substance to be detected, and the atoms or molecules in the substance to be detected absorb the energy of the excitation light. A transition will occur. The atoms or molecules after the transition are extremely unstable and will return to the stable state of the ground state at any time, and energy will be released when the transition state returns to the ground state, that is, molecules and atoms will produce fluorescence. The fluorescent light information is captured and analyzed by a spectrometer, so as to obtain what elements are ...
