Nanomegas was established in 2004 and specializes in advanced electron diffraction techniques for TEM. It was the first to develop and commercialize Precession Electron Diffraction (PED) device (“spinning star”) for structure solution, being able to retrofit various TEM electron microscopes. Today, our advanced solutions (hardware & software) include 4D–SPED (scanning precession electron diffraction) Phase & Orientation Mapping (ASTAR) down to 1 nm resolution, Strain mapping with a sensitivity of 0.02% down to 2-3 nm resolution, 3D Diffraction Tomography (ADT-3D) for crystal structure determination of nm size crystals and Electron Pair Distribution Function (e-PDF) for amorphous materials analysis. Our hardware product range is compatible with most commercial TEM electron microscopes (including Cs corrected TEMs) and latest technology CCD cameras / Direct Detection detectors. Actually, PED & electron crystallography related applications are present in every major electron microscopy/ X-Ray crystallography Congress worldwide ; there are more than 800 scientific publications (period 2004-2020) where Nanomegas related instrumentation has been used from more than 200 TEM laboratories worldwide.
