Abstract
The disclosure is a probelike apparatus ( ) for spectroscopic analysis of a fluid medium ( ) by attenuated reflection. Two light beams from a light source ( ) impinge upon the boundary ( ) between a prism ( ) and the medium ( ) to be analyzed and the intensities of the light beams reflected at the boundary are measured in a detector unit ( ). The two light beams differ in their angle of incidence on the boundary and/or in their polarization state. Measurement is preferably carried out under total reflection.
