Abstract
Various embodiments are directed to a device for detecting fluid particle characteristics comprising: a fluid composition sensor comprising: an illumination source configured to emit a light beam along a beam axis such that at least a portion of the light beam engages a collection media and illuminates particles disposed within a collection media; an imaging device configured to capture an image of the particles disposed within the collection media; and a light shield comprising: an internal shield portion enclosed within an inner surface of a shield wall; and one or more baffle elements disposed within the internal shield portion and configured to reflect at least a divergent portion of the light beam within the internal shield portion; wherein the light shield extends between the illumination source and the imaging device such that a portion of the light beam emitted along the beam axis passes through the internal shield portion.
