Diamond has become the standard optical material for ATR (attenuated total reflection) spectroscopy in the infrared. This technique uses the evanescent wave at the surface of single or multi-reflection ATR elements to evaluate the infrared absorption properties of liquids and solids with high sensitivity. This application takes advantage of the broad-band spectral transparency, the high refractive index and the robust surface of diamond.

Diamond Materials offers polished diamond rods with inclined facets for multi-reflection measurements.

In addition single-reflection ATR units with saw-tooth coupling structures are available.
