Near Infrared (NIR) Technology

NIR (Near Infrared) refers to an electromagnetic wavelength corresponding to about 780 to 2500 nm. NIR tissue measurements have been used to measure tissue chromophores to explain the health status of humans so far, e.g., pulse oximeter. Our real-time tissue measurements are made quantitatively in  spectral regions of about 650 to 1100 nm. Our devices use the light source of 8-wavelength NIR LED (Light Emitting Diodes) to calculate oxy-hemoglobin, deoxy-hemoglobin, water, and lipid by measuring tissue absorption and scattering during photon migrations.
