The EVAS evanescent wave absorption sensor consists of a sapphire fiber wound around a vertical PTFE shaft. The ends of the fiber are tapered up to facilitiate the coupling of light into and out of the probe.
The design permits the adjustment of the interaction length to accommodate the optimal analysis of spectral features. The EVAS is ideally suited for measurements in turbid fluids.
