Nion is a world-class developer of advanced scanning transmission electron microscopes and other electron-optical instruments. We work in close collaboration with our customers, developing instruments that answer real needs in the real world. Our microscopes elevate the concept of dedicated STEM (established by Prof. Albert Crewe and initially pursued mainly by VG instruments ) to a fundamentally new level. They combine a clean, bakeable vacuum, which minimizes contamination problems; advanced electron optics, which provides unprecedented resolution and makes available many operating modes; and complete flexibility that allows the instruments to be configured for new applications even after they have been installed. They combine user-friendly operation with ease of maintenance. They excel in the resolution obtained at low primary voltages and in the maximum current and the minimum energy spread they deliver into a small probe. A large part of our resources goes into research aimed at advancing the state of the art in electron microscopy. We design and make state-of-the art aberration correctors, sample stages, detectors, and cold field emission guns. This allows us to ensure that all the components work together seamlessly, and to deliver world-class instruments that function in an integrated and easy-to-use manner.
