O2 Sensors

 

 Fiber Optic Oxygen Sensors.

We offer a variety of highly stable fiber optic oxygen sensing options ranging from biological and medical applications to dissolved Oxygen in fuels, Petroleum products, solvents,  and other hydrocarbons.  For remote sensing we offer coated patches that adhere to the inside wall of the package, vessel window, or flow cell.  The coating on the patch will be selected for biological or hydrocarbon applications.  Read out is achieved with a fiber optic bundle probe connected to an Ocean Optics NeoFox phase flourimeter.  Combined with the NeoFox phase fluorimeter, the NeoFox viewer is a comprehensive software package that allows real time monitoring of the oxygen levels.  We also offer medical grade probes where a bifurcated fiber and splice bushing connects the probe to the fiber and read out with the NeoFox flourimeter.  

Principle of Operation:  The NeoFox transmitts 450 nm light into the probe and the flourescence quenching of the O2 level is detected by the sinusoidal phase shift  of the incident light to the red shifted flourescnce signal.  Since this is a time-based measurement, it provides a system that is robust and unaffected by light losses when using the patches inside package or vessel window.  The patch size will be determined by the wall thickness since the light from the fiberoptic bundle is divergent.  For this reason, patch sizes can be made to any diameter so the fluoresccence effectively couples back into the fiber bundle/Neofox Fluorimeter.  

We recommend factory calibration for all probes and patches and that you provide us with the expected O2 range and temperatures.  This provides an accurate readout and ease of use when setting up your system since the factory calibration file is simply downloaded into the NeoFox fluorimeter.  For fiber optic oxygen sensing read out  we use and recommend the Ocean Optics NeoFox phase fluourimeter combined with the NeoFox viewer and temperature probe.
