WAVEGUIDE TO BE USED AS OPTICAL PROBE IN MULTIPLE INTERNAL REFLECTION SPECTROSCOPIC ANALYSIS

摘要

Waveguide used as an optical probe in apparatuses for analyzing chemical or biochemical substances by multiple internal reflection spectroscopy. This guide comports, at the ends, prismatic deflectors whose optical angles are set to such value that the input and output wave signals inside of the deflectors are parallel to the optical axis thereof.
