Original abstract

To meet a required STEM resolution, the mechanical precision of the pole pieces of a magnetic lens needs to be determined. A tolerancing plugin in the EOD software is used to determine a configuration which both meets the optical specifications and is cost effective under the constraints of current manufacturing technologies together with a suitable combination of correction elements.

Czech abstract

Aby bylo dosaženo požadovaného rozlišení v STEM je třeba určit přesnost výroby pólových nástavců magnetických čoček. Toto je uděláno v modulu toleracnce v programu EOD.
