The invention provides a microplate reader to solve the technical problems that a halogen lamp is expensive and generates much heat in the prior art. The reader comprises a shell, a light path system,a signal processing system and a display screen; a cavity is formed in the shell, and a power supply and a CPU are installed in the cavity; the light path system comprises a light source assembly, alight filtering assembly, a multi-branch optical fiber and a light processing assembly, the light source assembly comprises a light source and a control circuit, the light source is integrated by a plurality of LED lamps with different wavelengths, and the control circuit comprises a digital switch and a plurality of constant-current power supply driving group circuits, wherein the digital switchis correspondingly and electrically connected with an LED lamp through one constant-current power supply driving group circuit, the CPU at least comprises a detection instruction receiving module anda control signal sending module, the control signal sending module is electrically connected with a control signal input end, the light filtering assembly, the multi-branch optical fiber and the lightprocessing assembly are sequentially connected along a light path; the signal processing system is connected to a CPU and comprises a photoelectric converter and a signal processor; and the display screen is arranged outside the shell and is electrically connected with the signal processor.
Description
technical field [0001] The invention relates to the technical field of chemical analysis, in particular to a microplate reader. Background technique [0002] The enzyme-linked immunoassay instrument is a special instrument for enzyme-linked immunosorbent assay, also known as a microplate detector, which is widely used in clinical testing, biological research, food and agricultural science research, and the enzyme-linked immunosorbent assay The field of reproductive health care has also been widely used to promote the improvement of reproductive health. At present, the optical system of the microplate reader mostly uses halogen lamp or xenon lamp light source, and cooperates with the monochromatic light generator to analyze and test the sample to be tested. Because the halogen lamp and xenon lamp are expensive, consume a lot of power, and generate more heat, etc. Or a variety of defects, which increase the cost of using the microplate reader, and if the high-temperature halo...
