SwissNeutronics is the world-leading supplier of advanced neutron optics, which are an inevitable equipment for the scientific instrumentation at modern neutron research facilities. Key developments are the super-polishing of large area substrates (glass, silicone, metals) and their coating with thin film neutron supermirror (multilayer stack up to 10000 layers). As a result, the reflectivity of the supermirror is approaching the theoretical limits. The excellent supermirror, combined with sophisticated designs and high precision machining and assembly enable for first-class neutron optical devices. Moreover, SwissNeutronics owns a profound expertise in the neutronic and engineering design of neutron optics and of complete beam lines as well as for their installation. These capabilities are also provided to industry in Switzerland, beyond the field of neutron optics.
