WebThe dual-tip optode has an increase detection area of 2x when compared to the single one. This means that there is an increase around 2x on sensitivity and a reduction in the gain average which improves signal quality. Each LED emits two wavelengths (760 nm and 850 nm) with 25 mW power and has 3 mm tip. WebOnly with this high-density sampling can fNIRS users be confident that the signal they record is truly from the brain. Comparison between standard fNIRS configurations and LUMO.
