1. A lithographic apparatus comprising:
- an array of individually controllable elements configured to provide a patterned radiation beam; and
a projection system configured to project the patterned radiation beam onto a target portion of a substrate, the projection system comprising;
an array of lenses arranged in a plane, such that each lens in the array of lenses is configured to transmit a different part of the patterned beam, andan actuator system configured to change a location of at least one lens with respect to other lenses such that the array of lenses is at least partially deformed from an original position such that the at least partial deformation is within the plane of the array of lenses.

Abstract
A lithographic apparatus has an array of individually controllable elements to impart a projection beam with a pattern in its cross-section. The projection system includes an array of lenses arranged in a plane and an actuator configured to change the location of at least one lens of the array of lenses such that the array of lenses is at least partially deformed where the at least partial deformation is within the plane of the array of lenses.

8. A lithographic apparatus comprising:
-
a system configured to direct a patterned beam onto a target portion of a substrate; and a substrate surface location detector configured to detect a configuration of surface of the substrate and to produce a signal based thereon, wherein the system comprises; lenses arranged in a plane, such that each of the lenses is configured to transmit a different portion of the patterned beam, and an actuator system configured to receive the signal and to change a location of at least one of the lenses with respect to other ones of the lenses based on the signal, such that the lenses are at least partially deformed from an original configuration, wherein the actuator system is configured to change the location of a first one of the lenses relative to a second one of the lenses, such that the at least partial deformation is within the plane of the lenses. - View Dependent Claims (9, 10, 11)
