Abstract
The invention is directed to a probe operative in the infrared region of the electromagnetic spectrum for in situ sensing of the absorption of IR energy in a sample. The probe comprises an attenuated total reflection (ATR) element having an input end and an output end for respectively receiving IR and transmitting attenuated IR. The ATR element has wall portions disposed about a central or long axis thereof for reflecting IR energy transverse to the central axis. A bundle of infrared transmitting fibers is located at the input end of the ATR element for transmitting and receiving IR energy into and out of the element. The fibers have end faces proximate the ATR element lying in a plane perpendicular to the central axis.
