Abstract
Assessment systems and methods are disclosed. In one arrangement, an effect of electrode distortion in an objective lens array is compensated. An electrode distortion is adjusted by varying an electrostatic field in the objective lens array. The adjustment is such as to compensate for an effect of electrode distortion on sub-beams of a multi-beam impinging on a sample. A sub-beam is refocused in response to the variation in electrostatic field in the objective lens array. The adjusting and the refocusing comprises changing potentials applied to at least two electrodes of the objective lens array.
