Specac - FTIR Calibration - Standard Polystyrene Wavelength

The Polystyrene wavelength standard is a certified wavenumber for calibration purposes, it is made of polystyrene film. It can be used to meet the requirements of FTIR – Mid IR and the wavenumber ranges from 545 cm^-1 to 3082 cm^-1 (14 peaks). There are two versions, one for ATR in the Mid-IR and the other for NIR region which have additional certified peaks.
