ABSTRACT:
Novel internal reflection plates and spectroscopy systems using such plates especially for analyzing liquids. The plates have a generally trapezoidal shape with beveled ends, and are oriented relative to an incident radiation beam such that the beam reflects from the bevel and propagates down the plate by multiple internal reflections form its major surfaces.
