Optical sensors

Optical sensors are the latest generation of biochemical monitors. Their benefit over electrochemical sensors is a simple design which improves reliability. Optical sensors generally use extrinsic indicators, typically either absorbance or luminescence, for the purposes of biochemical monitoring. Absorbent or luminescent materials are fixed to the optical fiber. Light of a given wavelength is transmitted through the optical fiber, and the change in wavelength returned for analysis corresponds to the magnitude of interaction between the solute of interested and the working matrix affixed to the tip of the optical sensor ( Lubbers 1,99.5).
