Abstract:
1. An optical computing device, comprising: an electromagnetic radiation source that emits electromagnetic radiation into an optical train to optically interact with a sample and at least one integrated computational element arranged within the optical train, the sample generating optically interacted radiation upon optically interacting with the electromagnetic radiation; a sampling window arranged adjacent the sample and allowing transmission of the electromagnetic radiation therethrough in order to generate the optically interacted radiation, the sampling window having one or more surfaces that generate one or more stray signals; a first focal lens arranged to receive the optically interacted radiation and the one or more stray signals and generate a primary focal point from the optically interacted radiation; and a structural element defining a spatial aperture aligned with the primary focal point such that the optically interacted radiation is able to pass therethrough while transmission of the one or more stray signals is substantially blocked by the structural element.
