Fiber Optic Oxygen Sensors

Photonics Buyers' GuideOxygen Sensors -- Fluorescence Quenching
Our oxygen sensors use the quenching of fluorescence by collision of molecular oxygen with a fluorophore that is trapped in an oxygen permeable sol gel or polymer. This technique is superior to electrodes in that O2 is not consumed. The sensing material can be put on the tip of an optical fiber, or made as a thin film on flat substrates (patches). We have a variety of sizes and shapes but they all work by the same principle. The NEOFOX "reader" is a phase fluorometer, which pulses a blue LED and measures the red fluorescence lifetime (tau) of the return signal. There are three chemistries available, ZERO-DRIFT AP for general purpose use in gases and aqueous based samples, MR hydrophobic sensor designed for fast response in gases, and HCR for use in aggressive hydrocarbon solvents such as toluene, alcohol, acetone and aviation fuels.

This is our best sensor yet! Our breakthrough multi-layered formulation has virtually no drift due to photo-bleaching. It is not influenced by water vapor, and so it can be calibrated in gases and used without error in liquids. It is very resistant to prolonged exposure to elevated storage and operating temperatures.

HCR Chemistry
HCR is formulated to work in organic solvents, which interfere with standard formulations. It features excellent adhesion in alcohols, jet fuels, toluene, acetone and many other hydrocarbons. We can test our probe in your solvent to validate its use. Just give us a call.

MR Chemistry
MR sensors are based on very hydrophobic sol gels, so the influence of water vapor on readings is eliminated without any degradation in response rate. It is ideal for measuring pO2 in gas mixtures where fast response is required.
