Abstract

The invention discloses a light shaping and homogenizing assembly. The assembly comprises a collimating optical element, a light homogenizing element and a focal length adjustable light condensing element, incident light is collimated into first light after entering the collimating optical element, the first light forms second light after being homogenized by the light homogenizing element, and the second light is condensed by the condensing element to form target light. The invention further discloses a laser lighting device and a gene sequencing system. According to the invention, the technical problems of improving the light uniformity and adjusting the spot size in the light shaping process are at least solved.

Description

technical field [0001] The invention relates to the field of optical technology. More specifically, the present invention relates to a light shaping and homogenizing component, a laser lighting device and a gene sequencing system. Background technique [0002] The gene sequencer needs to use a laser light source to illuminate the sample to be tested. The laser light source output by the optical excitation device (such as a laser) is usually Gaussian or super-Gaussian distributed light, that is, the light intensity distribution between the center and edge of the light is not uniform. Traditional gene sequencers usually shape the laser light source into a linear light by using a cylindrical mirror to shape the light. However, the cylindrical mirror shaping method cannot change the uniformity of the illumination spot. For two-dimensional light with Gaussian or super-Gaussian distribution, after After the cylindrical mirror is shaped and compressed in the one-dimensional direct...
