Diamond has a refractive index of about 2.4. It is suitable as an ATR prism, or crystal, because many samples have a refractive index much lower than 2.4. That means the critical angle of the sample is well below 45 degrees and a good quality ATR spectrum of can be obtained on a typical 45 degree fixed angle ATR accessory.
Diamond has a wide spectral range that exceeds the low wavenumber limit of many commercial FTIR systems, typically 400 cm-1. This is a key advantage over ZnSe (Zinc selenide), which has a lower limit at 550 cm-1 and often higher.
Diamond is hard and it makes for an excellent ATR prism for both soft and hard samples. ZnSe is a common ATR prism for soft samples (pastes and liquids) but it can still show signs of wear just from careful cleaning of the prism. Thus, diamond is preferred for it's durability but at about four times the price of ZnSe.
Summary: diamond ATR crystals have a wide mid-infrared spectral range and are highly durable. Many FTIR users find they are a practical necessity for hard samples and they have a long service life for both soft and hard samples.
