ELLIPSOIDAL MIRROR-BASED BIOFLUORESCENCE CAPTURING STRUCTURE AND CAPTURING METHOD

摘要

An ellipsoidal mirror-based biofluorescence capturing structure and a capturing method. The capturing structure comprises an ellipsoidal mirror (1), a capillary (3), and a fluorescence output optical fiber (6). The capillary (3) is mounted at a proximal focus of the ellipsoidal mirror (1). A reagent-marked biological test sample is mounted in the capillary (3). An extremity of the fluorescent output optical fiber (6) is arranged at a distal focus of the ellipsoidal mirror (1). When in use, a light beam is focused at the center of the capillary (3), the marked matter in the capillary (3) is excited to emit a light, thus producing fluorescence, the light source of the fluorescence radiates fluorescent photons to spaces in all directions, at which time, the radiated photons are reflected, light rays emitted from the near focus are converged to the distal focus, and the fluorescence output optical fiber (6) arranged at the distal focus of the ellipsoidal mirror (1) guides the fluorescence into the fluorescence output optical fiber (6) and then transmits same. The capturing structure is structurally compact, increases fluorescence capturing efficiency to the greatest extent, and reduces error of an optical system.
