FTIR Sampling

Polystyrene Mid Infrared Wavelength Reference

Polystyrene film has been a popular wavelength reference for mid-infrared spectrometers for many years. These new NIST-traceable Starna Reference Materials can be used to qualify Mid IR - FTIR spectrophotometers for wavelength accuracy over the range 3.2 µm to 18.5 µm (3125 cm-1 to 540 cm-1).Full Detail
