Embodiment Construction
[0021] see in conjunction Figure 1 to Figure 2 As shown, according to an embodiment of the present invention, a detection device capable of autofocus is provided, including: a laser emission source 1 for generating parallel light beams; a detection chip 2 having a detection area plane on it, and a detection area plane A detection channel 21 is configured to carry micro-droplets to be detected, and the position of the detection chip 2 relative to the laser emission source 1 in the horizontal direction can be adjusted. It can be understood that the detection chip 2 is relatively Translational motion is generated in the laser emitting source 1, so that the laser light generated by the laser emitting source 1 can be irradiated on different areas of the detection chip 2, and can pass through the detection channel 21; the objective lens 3 is located in the Between the laser emitting source 1 and the detection chip 2, it is used to focus the parallel light beam; the light intensity ...
