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.
L'invention est un spectroscope à réflectance utilisant un ou plusieurs trajets optiques qui empêchent les rayons lumineux réfléchis isolés d'atteindre la (les) destination(s) choisie(s). Cet appareil comporte une source lumineuse, un support pour tampon de réactif, ce support pouvant être placé de façon que le tampon de réactif soit éclairé par la source lumineuse, un indicateur de réflectance placé de façon à recevoir les rayons lumineux provenant du tampon de réactif, et un dispositif servant à établir un trajet optique qui empêche les rayons lumineux réfléchis isolés d'atteindre la destination choisie. Le trajet optique peut aller de la source lumineuse au tampon de réactif ou du tampon de réactif à la zone où se trouve le détecteur.
