ABSTRACT:
The present invention provides an optics assembly, a reflectometer, and a diagnostic device for providing quantitative measurement of optical radiation reflected from a sampling area on an assay matrix. The reflectometer includes an optical radiation source and a detector. The optical radiation source and the detector are mounted in a single plane. An optics assembly is configured to direct the illumination from the optical radiation source to the sampling area on the assay matrix and to direct the radiation diffusely reflected from the sampling area to the detector. The optics assembly is positioned over the face of the circuit board having the optical radiation source and detector mounted directly thereto. The present invention also provides a method for determining the presence of one or more selected analytes in a sample employing a plurality of sampling areas on one or more assay matrixes.
