The FTIR spectroscopic imaging systems couple FTIR spectrometers with liquid-nitrogen cooled MCT Focal Plane Array (FPA) detectors with 64x64 or 128x128 pixels, allowing multiple spectra from different spatial locations to be acquired simultaneously. The FPA detector can be placed in a macrochamber or large-sample compartment, allowing a variety of transmission or ATR accessories to be used, or in an infrared microscope, for high-resolution ATR and transmission/reflection imaging.
