Beer's Law1 / 4
- the intensity of transmitted light decreases exponentially as the CONCENTRATION of the substance increases
Lambert's Law2 / 4
- the intensity of transmitted light decreases exponentially as the DISTANCE travelled through the substance increases
Isobestic point3 / 4
- the point at which 2 substances absorb a certain wavelength of light to the same extent
- in pulse oximetry, the isobestic points of oxyHb and deoxyHb occur at 590 nm and 805 nm
