Concentration detection system

A concentration detection system comprising:

• a radiation source device which outputs a collimated beam of radiation across a sample path having an unknown concentration of fluid of interest;
• and
• a detector device including:
• a sample sensor,
• a reference sensor positioned adjacent the sample sensor and lying in the same plane as the sample sensor, and
• an integrating lens positioned to integrate the collimated radiation passing through the sample path evenly over the sample sensor and the reference sensor.

A concentration detection system comprising:

• a radiation source device including a radiation source and a collimating lens which forms a collimated beam of radiation output across a sample path having an unknown concentration of fluid of interest;
• and
• a detector device including:
• a sample sensor,
• a reference sensor, and
• an integrating lens positioned to integrate the collimated radiation passing through the sample path evenly over the sample sensor and the reference sensor.

A concentration detection system comprising:

• a radiation source device including a collimating one half ball lens which outputs a collimated beam of radiation across a sample path having an unknown concentration of fluid of interest;
• and
• a detector device including:
• a sample sensor,
• a reference sensor, and
• an integrating one half ball lens positioned to integrate the collimated radiation passing through the sample path evenly over the sample sensor and the reference sensor so that the instantaneous fields of view of the sample sensor and the reference sensor are the same to equalize any obscurations effects thereof.

A concentration detection system comprising:

• a radiation source device including a collimating lens positioned at a distance from a radiation source such that the radiation source is completely imaged by the collimating lens, collimating lens having a focal length greater than the distance between the collimating lens and the radiation source to output a collimated beam of radiation across a sample path having an unknown concentration of fluid of interest;
• and
• a detector device including:
• a sample sensor,
• a reference sensor, and
• an integrating lens positioned at a distance from the sample sensor and the reference sensor such that the sample sensor and the reference sensor are both completely imaged by the integrating lens, the integrating lens having a focal length greater than the distance between the integrated lens and the sample and reference sensors to integrate the collimated radiation passing through the sample path evenly over the sample sensor and the reference sensor so that the instantaneous fields of view of the sample sensor and the reference sensor are the same to equalize any obscurations effects thereof.

A concentration detection system comprising:

• a radiation source device including:
• a header,
• a filament supported above the header,
• a can mated with the header and including an aperture therein, and
• a collimating lens positioned in the can between the filament and the aperture which outputs a collimated beam of radiation across a sample path having an unknown concentration of fluid of interest;
• and
• a detector device including:
• a header having a reference sensor and a sample sensor mounted thereon adjacent each other,
• a filter pack above the reference and sample sensors,
• a can mounted with the header and including an aperture therein, and
• an integrating lens positioned in the can between the aperture therein and the filter pack to integrate the collimated radiation passing through the sample path evenly over the sample sensor and the reference sensor so that the instantaneous fields of view of the sample sensor and the reference sensor are the same to equalize any obscurations effects thereof.
