Problems solved by technology

This refocusing process will consume a lot of time and energy of the inspectors, thereby reducing the detection efficiency
[0005] In addition, the objective lens is designed with the imaging conditions of a certain surface (usually the first surface) of the biochip. Therefore, when the biochip surface (the first surface) designed by the objective lens is in the depth of field range of the objective lens, its image The quality can reach the diffraction limit; however, when the surface of the biochip that is not designed for the objective lens, that is, other surfaces of the biochip, such as the second surface, is within the depth of field of the objective lens, its image quality usually cannot reach the diffraction limit

Abstract

The invention discloses an imaging lens of a gene sequencer. The imaging lens comprises an objective lens, a compensating lens group and a barrel lens positioned on the same optical axis with the objective lens. The compensating lens group can enter or move out of the optical axis. When the compensating lens group enters the optical axis, the compensating lens group is located between the objective lens and the barrel lens. The invention further discloses a gene sequencer and a gene sequencing system. According to the invention, the technical problems of how to enable the multi-surface imaging quality of a biochip to reach the diffraction limit and how to reduce the focusing times of the objective lens on the basis of realizing the multi-surface clear imaging of the biochip are at least solved, and the focusing times of the objective lens can be reduced to one time.

Description

technical field [0001] The present invention relates to the technical field of gene detection. More specifically, the present invention relates to an imaging lens of a gene sequencer, a gene sequencer and a gene sequencer system. Background technique [0002] In the process of genetic testing, a gene sequencer is usually used to detect the biochip carrying the sample to be tested. The biochip usually includes a plurality of surfaces respectively carrying samples to be detected. If you want to clearly image the samples to be tested on multiple surfaces, you need to focus the imaging system of the gene sequencer several times. [0003] For example, in the case where the aforementioned multiple surfaces include the first surface and the second surface, when the biochip is detected, the first surface, the second surface and the objective lens of the gene sequencer are on the same optical axis. Due to the short depth of field of the objective lens, when the first surface is wi...
