发明名称 TARGET PROCESSING UNIT
摘要 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.

主权项 1. Target processing unit, comprising: a projection column for generating, shaping, and directing a beam toward a target, wherein the projection column comprises a projection lens assembly for directing the beam toward the target; a carrier frame for accommodating the projection lens assembly,wherein the projection lens assembly comprises: a flat lens support body for accommodating a lens element, wherein the lens support body spans a plane and comprises a connection region and a lateral edge, and wherein the lens support body is arranged for insertion along an insertion direction parallel with the plane into the carrier frame; a plurality of conduits emanating from the connection region and directed parallel with the plane; and a conduit guiding body arranged for accommodating the conduits,wherein the conduit guiding body comprises: a first guiding portion that is arranged for guiding the conduits from the connection region, parallel with the plane, and with a non-zero direction component perpendicular to the insertion direction, to a lateral region beyond the lateral edge; and a second guiding portion for guiding the conduits from the lateral region with a non-zero direction component perpendicular to the plane toward a tilted edge of the conduit guiding body.
