1. A system for analyzing a sample for the presence of an analyte in a sample, the system comprising:

  • a. a sample holder for containing the sample;

    b. an excitation source in optical communication with the sample, wherein radiation from the excitation source is directed to the sample, and wherein the radiation induces a fluorescence signal; and

    c. at least one linear array comprising;

    i. a proximal end disposed in proximity to the sample holder and an end port distal from the proximal end;

    ii. a plurality of optical fibers extending from the proximal end to the end port and having a first end and a second end, wherein the first ends of the individual optical fibers are substantially coplanar and adjacent to one another, and wherein the second ends of the optical fibers form a non-linearly arranged bundle, and wherein the plurality of optical fibers transmits the fluorescent signal from the proximal end to the end port; and

    iii. an end port assembly optically coupled to the end port, the end port assembly comprising a single photo-detector, wherein the photo-detector detects the fluorescent signal and converts the fluorescent signal into an electrical signal.
