Systems and methods of imaging a sample using a tilted charged-particle beam. The apparatus may comprise a first deflector located between the charged-particle source and an objective lens and configured to deflect the charged-particle beam away from the primary optical axis; a second deflector located substantially at a focal plane of the objective lens and configured to deflect the charged-particle beam back towards the primary optical axis; and a third deflector located substantially at a principal plane of the objective lens, wherein the third deflector is configured to shift a wobbling center of the objective lens to an off-axis wobbling location, and wherein the first and the second deflectors are configured to deflect the charged-particle beam to pass through the off-axis wobbling location to land on a surface of a sample at a first landing location and having a beam-tilt angle.
