    Abstract: The invention relates to a projection lens assembly for directing a beam toward a target. This assembly includes a lens support body (52) that spans a plane (P), and has a connection region (58) and a lateral edge (56). The lens support body is arranged for insertion into a frame (42) of a processing unit along an insertion direction (X) parallel with the plane (P). The projection lens assembly includes conduits (60-64) emanating from the connection region, and a conduit guiding body (70-81) for accommodating the conduits. The guiding body includes a first guiding portion (72) for guiding the conduits from the connection region, along the plane to a lateral region (B) beyond the lateral edge. The guiding body also includes a second guiding portion (78) for guiding the conduits from the lateral region (B) toward a tilted edge (79) of the conduit guiding body.

    Abstract: An electron beam device for inspecting a target substrate or specimen thereon includes a beam separator with an asymmetric quadrupole electrostatic deflector for improving field uniformity for a single direction of deflection. The asymmetric quadrupole electrostatic deflector includes two orthogonal electrode plates spanning roughly 60 degrees and two electrode plates spanning roughly 120 degrees, the two latter plates defining a unidirectional deflection field. The device generates a primary electron beam and focuses the primary electron beam along an optical axis into the target substrate. Secondary electrons detected at the target substrate are focused into a secondary electron beam. The beam separator with asymmetric quadrupole electrostatic deflector deflects the secondary electron beam away from the axis of the primary electron beam in the direction of deflection and into a detector array.
