Dual Beam Helios 650

The Dual Beam Helios 650 model is an improved version of the Helios 600 one. Thus, the SEM column has resolution of 0.9 nm and it bears a monochromator and beam deceleration. The FIB column is differentially vacuum-pumped at the lowest part, allowing a well-defined beam profile impacting on the sample surface. Results with such a column indicate that ultranarrow nano-deposits can be grown. This Focused Ion Beam (FIB) column is nicely suited for lamellae preparation too, in combination with the Omniprobe nanomanipulator.
