Fluorescence excitation system, optical system and real-time fluorescence quantitative PCR instrument

Abstract

The invention discloses a fluorescence excitation system, an optical system and a real-time fluorescence quantitative PCR instrument. The fluorescence excitation system comprises a first free-form surface reflector, at least two excitation light sources and a sample table, wherein the at least two excitation light sources are positioned between the first free-form surface reflector and the sample table; and excitation light emitted by the at least two excitation light sources is reflected by the first free-form surface reflector and is converged on the sample table. Multiple paths of independent excitation light sources are adopted, and through reflection of the free-form surface reflector, all the paths of excitation light are converged on the sample table and used for exciting fluorescence. When the spectral energy of a certain wave band needs to be improved, only the intensity of the excitation light source corresponding to the spectrum of the wave band needs to be improved; and if one or more of the multiple excitation light sources are damaged, the damaged excitation light source can be directly replaced, and the use of the whole real-time fluorescent quantitative PCR instrument is not influenced.
