This graph illustrates the principle behind pulse oximeters, which gained attention during the COVID-19 pandemic. It displays the wavelength-dependent difference in molar extinction coefficients between hemoglobin bound to oxygen (HbO₂) and hemoglobin that has released oxygen (Hb) (please press the "Calculate" button first, then the "Graph" button).
I have divided the raw data (source provided in the link) into several segments, each 2 nm apart, and approximated it using a sixth-order function.
