WebFTIR stands for Fourier transform infrared, the preferred method of infrared spectroscopy. When IR radiation is passed through a sample, some radiation is absorbed by the sample and some passes through (is transmitted). The resulting signal at the detector is a spectrum representing a molecular ‘fingerprint’ of the sample. WebAn FTIR Microscope uses reflection optics to observe and focus infrared light onto samples. Transmission, Reflection, Attenuated Total Reflectance, and Grazing Angle objectives are …
