| Zusammenfassung: | The utility model relates to a fluorescent detector field, prism type evanescent wave fluorescence sensor is disclosed, it includes the light source, prism (10) and detector (20), light beam (23) areplane of reflection (21) through the side that prism (10) takes place the total reflection, the outside of plane of reflection (21) is provided with fluorescent material layer (22), the total reflection takes place for light beam (23) that the light source sent in prism (10), light beam (23) produce the evanescent wave to the outside of plane of reflection (21) when plane of reflection (21) takesplace the total emission, evanescent wave fluorescence excitation (24) material produces fluorescence (24), fluorescence (24) are surveyed by detector (20) and are caught. Prism (10) are isosceles right -angle triangle -shaped's total reflection prism for the cross section. This device has background noise and hangs down, and it is accurate to measure, and the space occupies advantages such as little.
