1. An instrument for detecting a reflected wavelength from a surface of a biosensor, comprising:

  • a light source for generating a collimated quantity of white light;

    an illuminating fiber optically coupled to said light source, said illuminating fiber illuminating an illumination area of said surface of said biosensor;

    a detecting fiber for detecting light reflected from said surface; and

    a measuring apparatus including a spectrometer that processes said reflected light and derives a peak wavelength value of said reflected light.
