Fiber optic spectroscopy is a technique of remote sensing that is used for compositional or physical property measurement. Infrared, visible or ultra-violet energy is launched into a fiber optic assembly and is interfaced with the sample by means of an optical probe. The sample absorbs the radiation differently at various wavelengths and the remaining energy is sent back to the analyzer where it is measured as a function of wavelengths. Today’s spectroscopic instrumentation can be installed in the laboratory, at-line or directly into the process stream, dryer, extruder or reactor. The most appropriate type of spectroscopic measurement will be dictated by the physical and optical properties of the sample or process medium.
