FTIR Spectroscopy, is an analytical technique used to identify organic, polymeric, and, in some cases, inorganic materials. The FTIR analysis method uses infrared light to scan test samples and observe chemical properties. IR Spectroscopy measures the vibrations of atoms, and based on this, it is possible to determine the functional groups.

Atomic-force microscopy (AFM) or scanning-force microscopy (SFM) is a very high-resolution type of scanning probe microscopy (SPM), with demonstrated resolution on the order of fractions of a nanometer. A scanning probe microscope is an instrument for positioning a sharp tip at a defined distance above the surface of sample. Using an atomic-force microscope (AFM), it is possible to measure roughness of a sample surface at a high resolution, to distinguish a sample based on its mechanical properties (for example, hardness and roughness) and, in addition, to perform a micro fabrication of a sample.

Scan range:   1 - 50 µm
Roughness:    2.7 µm
