Evanescent field absorption sensor for detection of copper (II) in water using multimode optical fiber

Abstract

The evanescent field absorption sensor for the detection of trace amount of copper (II) in water is experimentally analyzed with the etched step index multimode plastic clad silica (PCS) fiber. The designed sensor is sensitive to copper (II) content in water with a range up to 250 ppm.
