<p>A reflectance spectroscope, which is provided with one or more optical paths which prevent substantially all singly reflected light rays from reaching the intended destination(s), is provided with a source of illumination for generating light rays, a support member adapted to support a reagent pad, the support member having a position in which the reagent pad is illuminated by the light rays generated by the illumination source, a reflectance detector positioned to receive light rays from the reagent pad, and means for defining an optical path in which substantially all singly-reflected light rays are prevented from reaching the intended destination. The optical path may be between the illumination source and the reagent pad, or between the reagent pad and the area in which the detector is provided.</p> |
