ABSTRACT:
A multiple internal reflectance crystal has a sample surface and a bottom surface and reflective beveled ends such that energy may enter normal to the bottom surface, reflect off one beveled end to the bottom surface, from the bottom surface to the top surface, down the length of the crystal, and exit the crystal normal to the bottom surface by reflecting off of another beveled end. The crystal may be optically linked with light pipes and positioned at a location remote from the source and receiver of energy.
