Optical fluid sensors for cross contamination control systems

The present invention relates to an optical fluid sensor. The sensor comprises a body defining a chamber and having one or more apertures to allow a fluid to enter the chamber. A light source is optically coupled to the chamber and is configured to emit IR, UV, and visible light into the chamber. A detector is optically coupled to the chamber and is configured to receive light from the chamber. The detector measures an intensity of one or more wavelengths of light received by the detector. The light source and the detector are positioned such that, when fluid is disposed within the chamber, emitted light from the light source passes into and through the fluid disposed in the chamber before being received by the detector. A first temperature sensor is operatively arranged within the chamber to measure a temperature of the fluid disposed in the chamber. A second temperature sensor is operatively arranged in the body to measure a temperature of the light source and the detector. Figure 1 I/ls
