Claim Text:
1. An optical computing device, comprising: a sampling window arranged on a housing and having an inner surface exposed to an interior of the housing and an outer surface exposed to a substance to be monitored; an electromagnetic radiation source configured to emit electromagnetic radiation into an optical train defined within the housing, the electromagnetic radiation being configured to optically interact with the substance; at least one integrated computational element (ICE) core arranged in the optical train and configured to optically interact with the electromagnetic radiation; and a detector arranged within the optical train and configured to receive the electromagnetic radiation following optical interaction with both the substance and the at least one ICE core, the detector being further configured to generate an output signal corresponding to a characteristic of the substance, wherein the electromagnetic radiation impinges upon the surfaces of the sampling window wherein specular reflected light reflects off the sampling window at an opposing angle of incidence, the specular reflected light emanating away from the sampling window such that it is not detected by the detector.
