The invention belongs to the field of optical detection, and discloses a near-full-angle fluorescence collecting device which is designed according to the following steps that the structure of the near-full-angle fluorescence collecting device is designed, and a first curved surface (partial ellipsoid) and a second curved surface (partial spherical surface) form a fluorescence collecting cavity; the light-sensitive surface of the light detector faces the center of the ball and is perpendicular to the long axis of the ellipsoid, and the center of the light-sensitive surface is located at the center of the second curved surface; the first focus of the ellipsoid coincides with the center of the ball, and the second focus is close to the photosensitive surface. And according to the radius # imgabs0 # of the ball and the diameter # imgabs1 # of the light-sensitive surface, calculating to obtain a reference range # imgabs2 # of an ellipsoid focal length corresponding to full-angle fluorescence collection when fluor
