摘要：An optical system which may be a component of apparatus for assaying a fluid sample with radiation is capable of exciting fluorescence in fluorescent material and includes a totally internally reflecting, unitary elongated substrate transmissive to both the excitation radiation and to the fluorescence. The fluorescent material includes at least a moiety of an antibody-antigen complex that includes a tag that will provide the fluorescence when excited by an evanescent wave generated by the excitation radiation. The substrate includes an elongated fiber and an integral lens formed to guide the optical radiation into the fiber within the bounds of a critical angle to assure total internal reflectance. A hollow elongated enclosure is dispod concentrically about and spaced from the fiber so as to provide an interspace of capillary dimensions. A test implement supports the elongated substrate such that the fluid sample is caud to flow onto the fiber and, by capillary action, into the interspace between the fiber and the enclosure. The apparatus further includes a source of the excitation radiation, refractive means for focusing the radiation toward the lens substantially in the region thereof at which evanescent wave coupling occurs, detector means for detecting fluorescence radiation emitted from an end of the fiber responsively to the excitation radiation, and optics
