Sodium Chloride Window (NaCl) Description
Sodium Chloride Window (NaCl) is a material commonly used in FTIR spectroscopy. It is a cubic crystal material with excellent transmittance between 250nm-16μm. It has a natural ability to absorb moisture, so the sample must not contain any moisture. Sodium chloride windows are sensitive to thermal shock but can be used in environments with temperatures up to 400°C.
