1. A device for detecting fluid particle characteristics comprising:
a fluid composition sensor configured to receive a volume of fluid containing a plurality of particles, the fluid composition sensor comprising:
a fluid flow chamber disposed within an internal sensor portion and defining at least a portion of a fluid flow path, the fluid flow chamber being configured such that the volume of fluid flows through a fluid flow chamber outlet towards a collection media configured to receive one or more particles of the plurality of particles;
an illumination source configured to emit one or more light beams along a beam axis such that at least a portion of the one or more beams engage the collection media and illuminates the one or more particles received by the collection media;
an imaging device configured to capture an image of the one or more particles received by the collection media;
a light shield comprising an internal shield portion defined within an inner surface of a shield wall, the light shield extending at least partially between the illumination source and the imaging device such that at least a portion of the one or more light beams emitted along the beam axis pass through the internal shield portion;
wherein at least a portion of the light shield is disposed within the fluid flow chamber such that the volume of fluid and the least a portion of the one or more light beams pass through the fluid flow component outlet.
