    Abstract: An optical detection system includes a sample carrier receiving region that receives a sample carrier carrying a sample. The system further includes a source that emits an excitation signal having a wavelength within a predetermined wavelength range. The excitation signal illuminates the sample carrier. A first sub-portion of the excitation signal is absorbed by the sample, which emits characteristic radiation in response thereto. A second sub-portion of the excitation signal traverses the sample carrier. The system further includes a detector that detects the characteristic radiation. The system further includes an absorber that absorbs the excitation signal traversing the sample carrier without being absorbed by the sample or sample carrier. The absorber absorbs at least 95% of the excitation signal traversing the sample carrier.

    Abstract: The composition of a particle occurring on the surface of a smooth substrate is identified by impinging the surface with a light beam having a strong P-polarized component at an oblique angle of incidence to the surface, and collecting light scattered from the surface at forward, center, and back locations relative to the portion of the surface impinged by the incident beam. The intensities of the light collected at these locations are measured by detectors and converted into signals, and the magnitudes of the signals are compared to correlations of particle material as a function of the relative magnitudes of the forward-, center-, and back-scatter signals so as to identify the material whose correlation most nearly matches the measured detector signals. Preferably, a ratio of the back detector signal magnitude to forward detector signal magnitude is correlated with particle material and back detector signal magnitude. Alternatively or additionally, a ratio of back detector signal magnitude to center detector signal magnitude is correlated with particle material and back detector signal magnitude. Average particle diameter versus back detector signal magnitude is correlated with particle material.
