Photo Optic Sensors

Photo Optic sensors include both photo optic components and complete sensor solutions. The component series features dual-LED, bi-wavelength emitters, and spectrally paired photodetectors.

The optics are suited for medical applications where a selection of peak wavelength is a priority, such as pulse oximetry (SpO2). We also package our optics into complete probe assemblies for pulse oximetry monitoring applications. Our SpO2 probe platform includes reusable finger clips, soft silicone boots, and a range of disposable sensors.
