Abstract
Description
Technical Field
[0001] The utility model relates to the technical field related to gene sequencing, and more precisely to a dual-fiber output laser module for a gene sequencing instrument. Background Art
[0002] Gene sequencing technology is a new type of gene detection technology that can analyze and determine the full gene sequence from blood or saliva, predict the possibility of suffering from various diseases, individual behavioral characteristics and behavioral rationality. Gene sequencing technology can lock in an individual's diseased genes and prevent and treat them in advance. Gene sequencing is completed by a gene sequencing instrument. Existing gene sequencing instruments usually use capillaries to hold samples and reagents. Laser irradiation is required to stimulate the internal reagents of each capillary during detection. In order to improve the detection efficiency, this field often uses a capillary array composed of multiple capillaries for detection. Since the capillary array is relatively large in size, the use of a single laser beam for excitation will cause the capillaries at different positions in the array to receive different light intensities, affecting the accuracy of the detection.
[0003] At present, in order to solve the problem of uneven received light intensity in the capillary array, a laser module is used to output two laser beams. The laser module includes a laser and a beam splitting structure. The beam splitting structure is used to split the output light of the laser into two beams of split light, and the two beams of split light are guided to enter the opposite ends of the capillary array respectively, so as to improve the uniformity of irradiation. The existing beam splitting structure is generally composed of a color separation mirror box and several reflectors. The color separation mirror is used to split the output light of the laser into two beams of split light, and then the two beams of split light are reflected multiple times to the opposite ends of the capillary array through several reflectors. The existing beam splitting structure occupies a large space and is difficult to adjust. It is easy to have deviations and cannot be easily adapted to capillary arrays of different specifications.
[0004] In summary, the art requires a laser module that occupies less space and is more convenient to adjust. Utility Model Content

[0006] In order to achieve the above-mentioned purpose, the utility model provides a dual-fiber output laser module, comprising a laser, two optical fibers and two beam shapers, wherein one end of each of the two optical fibers is connected to the output end of the laser, and the other ends of the two optical fibers are respectively connected to the beam shapers, and the output ends of the beam shapers are respectively aligned with the opposite ends of the capillary array.
[0007] Preferably, the optical fiber has a plurality of coiled portions.
