    摘要: A detection system (100, 150, 180, 200, 220, 250) for detecting luminescence from at least one sample (108) when excited by incident excitation radiation. Detecting luminescence may allow to detect, for example, biological, chemical or bio-chemical particles. The detection system (100, 150, 180, 200, 220, 250) comprising at least one optical component (102) with at least a first surface (104). The first surface (104) of the at least one optical component (102) is located to internally reflect incident excitation radiation to create an evanescent field outside the at least one optical component (102) for exciting the at least one sample (108). The detection system also comprises at least one detector element (110) that is in direct contact with the at least one optical component (102) to detect the luminescence from at least one excited sample (108) through the at least one optical component (102).
