Gene Sequencing Optical System

Abstract

The invention provides a gene sequencing light-path system. The gene sequencing light-path system disclosed by the embodiment of the invention comprises two excitation light sources, the two excitation light sources are running simultaneously, two light beams are combined by a first beam combiner, and then the combined light beam passing through a main beam splitter mirror, after being focused by a focusing microscope, is irradiated on a to-be-detected sample. Therefore, the gene sequencing light-path system can achieve an effect of simultaneously exciting visible light with various specific wavelengths, thereby improving the sequencing efficiency of the gene sequencing light-path system.

Description

technical field [0001] The invention relates to an optical path system, in particular to a gene sequencing optical path system. Background technique [0002] In the last three decades, remarkable progress has been made in decoding the genomes (the encoded forms of all inherited traits) of organisms ranging from simple viruses to humans and other mammals. Various tools have been developed over the years to assist in the decoding or sequencing of such genomes. Given the extreme complexity of the genomes of more complex organisms, such as humans, the time and cost involved in sequencing such genomes is quite high. The sequencing of the first human genome took 13 years and $3.5 billion, and would cost incrementally about $300 million to repeat today. However, advances in sequencing technology and equipment have resulted in corresponding improvements in the speed and cost of performing such sequencing. The second human genome, announced in September 2007, took a year and $70 m...

Problems solved by technology

In the traditional optical path system using pyrosequencing technology, two kinds of excitation light sources are set up to scan the samples to be tested alternately. Alternate testing makes the efficiency of the entire gene sequencing lower.
