摘要:
The invention provides an optical system for a charged particle multi-beam system. The optical system comprises an electrostatic lens component and a magnetic lens component. The components are used to focus a plurality of charged particle beams in a separate opening for each of at least a plurality a charged particle beams traveling through the optical system.
