Established in 1989, Ocean Optics is creator of the world’s first miniature fiber optic spectrometer and a global leader in optical-sensing technologies. We offer an extensive line of complementary technologies including spectrometers, fiber optic chemical sensors, metrology instrumentation, optical fibers and accessories.

Our sensors are ideal for applications ranging from monitoring gaseous oxygen pressure in headspace to determining the pH of liquids and slurries. Our O2 sensors use a sol-gel coating embedded with an oxygen indicator and applied to patches or probes. Patches are useful for measuring headspace and other parameters inside packages; probe options range from slender fibers for fine spatial resolution to robust, ¼-inch OD probes for process environments. Coatings are available for general lab use, high-sensitivity applications and hydrocarbon-rich sample environments. Here’s how the sensors work: A transducer material is trapped in a sol-gel coating that is applied to the probe or patch. When the material changes optical properties in response to specific analytes in its immediate environment, the sensor measures the response. Unlike polarographic and galvanic oxygen meters, our optical oxygen sensors are immune to environmental changes in pH, salinity and ionic strength. Other advantages include no sample consumption, infrequent calibration and no disturbance from EMI.
