Stelar is an independent Italian company specialized in scientific instrumentation for Magnetic Resonance. Stelar is established in Mede, Italy, on 1984 with the mission to develop, manufacture and market innovative Scientific Electronic Instrumentation for NMR research and industrial applications.Beginning 1994 Stelar introduces an innovative method and instrumentation for a novel measuring technique in NMR relaxometry. This method, called NMR Fast Field Cycling is the only technique which allows to measure T1 dispersion curves (NMRD profiles) as a function of field strength starting from earth field up to the fields where the other conventional NMR spectrometers are applicable.The NMR FC method has been adopted in many NMR laboratories and nowadays dozens of Fast Field Cycling Relaxometers are installed in Europe, North America and Asia and successfully applied in many field of application in material science, liquid crystals, polymers, MRI contrast agents, biological. Stelar is recognized leader in this field. Stelar is at present committed to the diffusion of the knowledge and the use of Field Cycling NMR method in scientific and industrial research and is involved in many R&D projects for the continuous development of new FC applications in NMR and MRI exploiting latest technologies of electronic design
