MicroImplant - Implantable Oxygen MicrosensorFeatures Implantable oxygen microsensor 2. 5m cable 0 250% Air saturation 50um tip OPTIONS 501658 C This sensor is coated for otical isolation. The optical isolation is an optional, opaque, oxygen permeable material that can be coated over the luminophore that prevents ambient light from reaching the sensor and also prevents excitation light from escaping. This coating lengthens the reponse time due to the adtional layer of material that oxygen must
