    • A charged particle optical system for testing, imaging or inspecting substrates comprises: a charged particle optical assembly configured to produce a line of charged particle beams equally spaced along a main scan axis, each beam being deflectable through a large angle along the main scan axis; and linear detector optics aligned along the main scan axis. The detector optics includes a linear secondary electron detector, a field free tube, voltage contrast plates and a linear backscattered electron detector. The large beam deflection is achieved using an electrostatic deflector for which the exit aperture is larger than the entrance aperture. One embodiment of the deflector includes: two parallel plates with chamfered inner surfaces disposed perpendicularly to the main scan axis; and a multiplicity of electrodes positioned peripherally in the gap between the plates, the electrodes being configured to maintain a uniform electric field transverse to the main scan axis.

    • Disclosed is a method and apparatus for generating an image from a sample using a charged particle beam. The apparatus further includes a measurement device (228) arranged to measure a characteristic of the sample portion to obtain a surface voltage value of the sample portion that is exposed to the charged particle beam. For example, the measurement device is an electrostatic voltmeter positioned to obtain a surface voltage value of the exposed sample portion. A charged particle beam is directed substantially towards a portion of the sample under a first set of operating conditions. A surface charge value of the sample portion is obtained under the first set of operating conditions. It is then determined whether an optimum set of operating conditions associated with a predetermined surface charge value have been found. When the optimum conditions have not been found, the operating conditions are adjusted and the charged particle beam is directed substantially towards the sample portion. When the optimum conditions have been found, the charged particle beam is directed substantially towards the sample portion under the found optimum operating conditions.
