Abstract: A system with a radiation source device (40) which outputs a collimated beam of radiation (42) across a sample path having an unknown concentration of fluid of interest and a detector device (46) including a sample sensor (48), a reference sensor (50), and an integrating lens (56) positioned to integrate the collimated radiation (42) passing through the sample path evenly over the sample sensor (48) and the reference sensor (50) so that the instantaneous fields of view of the sample sensor (48) and the reference sensor (50) are the same to equalize any obscurations effects.
