Paper Abstract

In this paper we present the analysis, design, and construction of a fiber optic evanescent field sensor. A standard PCS multimode fiber was used in a measurement method called the attenuated total reflection. We present sample measurements taken for an alcohol solution of cobalt chloride CoCl2(DOT)6H2O compared with the results obtained by methods of classical spectrophotometry. The sensor described can be used in the analysis of strongly absorptive substances, especially where the traditional- optical transmission-measurement methods are impossible.
