FTIR spectrometers are mostly used for measurements in the mid and near IR regions. For the mid-IR region, 2−25 μm (5,000–400 cm ), the most common source is a silicon carbide (SiC) element heated to about 1,200 K (930 °C; 1,700 °F) (Globar). The output is similar to a blackbody. Shorter wavelengths of the near-IR, 1−2.5 μm (10,000–4,000 cm ), require a higher temperature source, t… WebJan 18, 2015 · The SEM used for the characterization is equipped by Genesis EDX spectroscopy system that was used to measure the composition of the elements constituting the films.
