Fluorescence detecting system for quantitative gene magnification instrument

[0010] Quantitative gene amplification instruments are generally composed of a fluorescence detection system, a data processing system and a display system. The fluorescence detection systems of the existing quantitative gene amplification instruments are such as figure 1 1-1 is the excitation light, 1-2 is the fluorescence emission, 1-3 is the sample, 1-4 is the sample base, 1-5 is the cap scattered light, 1-6 is the cap, 1- 7 is the liquid surface scattered light, 1-8 is the sample liquid level. When the excitation light is reflected by the sample and reaches the interface 1-8 between the sample liquid and the air, part of the light scattering 1-7 occurs, and then when the reflected light reaches the cap 1-6, light scattering 1-5 occurs again, thus The intensity of light is greatly weakened, which affects the sensitivity of detection.

[0011] The quantitative gene amplification instrument of the present invention is also composed of a fluorescence detection system, a data pro
