Portable emission FTIR spectrometer for Thermal Infrared (TIR) remote and proximal sensing applications

D&P Instruments’ portable FTIR spectrometer (Model 102), also known as the micro FTIR among the scientific community, is a passive-mode FTIR spectrometer, which measures the radiation emitted by the object itself. Thus, it serves as the ideal instrument for thermal infrared (TIR) remote sensing applications, where non-destructive testing is mandatory or where spectral field measurements (validation/calibration) have to comply with the requirements necessary for a quantitative comparison with emission spectra obtained via an air- or spaceborne TIR remote sensor. It’s also the product of choice for gas detection and analyses, as the FTIR-technique allows for very high spectral resolution.

The compact and portable micro FTIR is ideally suited for outdoor use and incorporates a thermally stabilized interferometer, which is available with either a liquid nitrogen or a stirling cooled dual InSb/MCT detector. This passive mode FTIR spectrometer provides the user with emission radiance spectra (which can be transformed to emissivity/temperature via TES) ranging from 2 μm to 16 μm with a spectral resolution of 4 cm-1.
