Nicolet Technologies (later Thermo Nicolet and Thermo Scientific) is a historic pioneer in Fourier Transform Infrared (FT-IR) spectroscopy. Because 'FT-IR' represents a broad class of instruments spanning several generations of spectrometers (including the Nicolet Avatar, Nexus, Magna, iS, and Summit series) rather than a single specific model, numerical parameters such as size, weight, spectral resolution, and signal-to-noise ratio vary by specific instrument configuration. However, core architectural features like the Michelson interferometer design, HeNe reference laser calibration, OMNIC software control, and versatile sampling compatibility are shared across the Nicolet family.
