The size of the write fields can be adjusted from 0.5 micron to 2 mm, the minimal beam size at 20 kV accelerating voltage is 1.6 nm. The minimum periodicity of the gratings produced by the system does not exceed 40 nm, and the minimum feature size is smaller than 8 nm. For imaging, the system is equipped with an off-axis Everhart-Thornley secondary electron detector and an in lens, combined secondary and backscattered electron detector. Analyzing the chemical composition of the investigated samples is also possible with an X-ray spectrometer and energy dispersive microanalysis system (EDS), capable to detect elements with atomic number between 5-95.
