FEI (Thermo Fisher Scientific) Scios2 LoVac dual beam FEG/FIB SEM.Scios2

Electron Optics

Scios 2 LoVac features a pre-aligned electron optical column, which is optimized for high resolution and for beam stability. The main elements of the electron optical system are:

Source:Field emission gun assembly with Schottky emitter source. The assembly is optimized for high brightness/high current, providing low-noise imaging. The pre-alignment of the FEG ensures no mechanical alignment is required. Easy gun installation and maintenance is provided with Auto bake-out and Auto Start capabilities.
