Optical path 

Infrared radiation is directed into the crystal from the front half of the upper cassegrain, and 

is focused at the sample position. It is reflected once within the crystal, then the totally 

internally reflected beam is collected by the rear portion of the upper cassegrain, which 

focuses it on the remote aperture. The radiation is directed onto the detector in the imager.
