Fourier Transform (FT) Spectrometers are advanced analytical instruments used to obtain high-resolution spectra of samples by measuring the interference pattern of light and applying a mathematical Fourier Transform. Commonly employed in infrared (FTIR) and near-infrared (FT-NIR) spectroscopy, they enable precise qualitative and quantitative analysis of chemical composition, molecular structure, and functional groups. FT spectrometers are widely used in chemistry, pharmaceuticals, environmental analysis, and materials science for applications such as polymer characterization, quality control, and molecular identification.
