Fluorescence detection chip

The invention discloses a fluorescence detection chip. The fluorescence detection chip comprises two cover plates, wherein a reflecting mirror is mounted on one of the cover plates along an ellipse-shaped circumference, a lens is inserted and mounted on a focal point of the ellipse, and a detection pool is mounted on the other cover plate, and the detection pool is positioned on the focal point of the ellipse corresponding to the lens; a detector is mounted on one of the cover plates, the detector is positioned on the other focal point of the ellipse, and an optical filter is tightly attached and mounted on the side face, facing the lens, of the detector. The fluorescence detection chip disclosed by the invention is simple in structure and reliable in performance, the collecting efficiency of fluorescence is greatly improved by utilizing the optical properties of the ellipse, and the fluorescence detection chip can be widely applied to the fields of water quality detection, biological detection, medical detection and the like.
