Abstract

In modern measurement technology of biological processes and process measuring technology, optical measuring methods to determine concentration are indispensable. To make qualitative and quantitative materials analyses, attenuated total reflection (ATR) or evanescent spectroscopy can be used. A new method to calculate the evanescent absorption is discussed. Theoretical context was verified by experimental investigations about evanescent absorption on quartz rods in the visual spectral range. A sensor for IR-measurements is described.
