Method, apparatus, and article to facilitate evaluation of substances using electromagnetic energy

Sampling device geometry reduces specular reflectance, using lenses to focus electromagnetic energy to predominately return scattered rather than reflected electromagnetic energy to detector(s), reducing effect of non-matte surfaces and/or window. Sampling device includes inherent automatic optical...

Zusammenfassung:Sampling device geometry reduces specular reflectance, using lenses to focus electromagnetic energy to predominately return scattered rather than reflected electromagnetic energy to detector(s), reducing effect of non-matte surfaces and/or window. Sampling device includes inherent automatic optical calibration, and optionally thermal calibration. Calibration detectors are optically isolated with respective emitters.
