Abstract:
A multi-beam apparatus for observing a sample with high resolution and high throughput and in flexibly varying observing conditions is proposed. The apparatus uses a movable collimating lens to flexibly vary the currents of the plural probe spots without influencing the intervals thereof, a new source-conversion unit to form the plural images of the single electron source and compensate off-axis aberrations of the plural probe spots with respect to observing conditions, and a pre-beamlet-forming means to reduce the strong Coulomb effect due to the primary-electron beam.

Claim (Index 3):
The multi-beam apparatus according to  claim 1 , wherein said movable collimating lens comprises at least two single magnetic lenses which are placed at different axial positions along and aligned with said primary optical axis, and excitations thereof can be adjusted to move said first principal plane so as to vary said currents of said plurality of beamlets.
