Description

technical field [0001] The invention relates to the field of fluorescence detection, in particular to a fluorescence detection optical system. Background technique [0002] Biochip technology is to use micro-processing technology combined with related chemical synthesis technology to immobilize a large number of probe molecules on the carrier to make a biochip. The probe molecules are hybridized with the sample molecules labeled with tracers. The distribution and strength of the tracer signal can be used to obtain information such as the sequence and quantity of the target molecule. The detection of tracer signals is an important part of biochip technology, which determines the rapidity and accuracy of biochip technology. At present, fluorescent substances are commonly used as tracers. In the fluorescence detection method, the base carrying the fluorescent material is combined with the genetic material of the sample. When excited by the excitation light source, the fluoresc...
