We design Einzel lenses to aid in focusing an ion beam through magnet chambers and into electrostatic accelerators. NEC Einzel lenses are typically used for applications involving ion beams in the range of 10s to 100s of keV.
Einzel lenses consist of three sets of cylindrical apertures in series along an axis. The energy of the ions exiting the lens is unchanged from when the ions enter.
NEC offers many models with various aperture diameters and voltage ratings. As with other NEC lenses, custom models can be provided upon request.
