    Abstract: A lithographic apparatus comprises an illumination system configured to condition a radiation beam, a support to support a patterning device, a substrate table to hold a substrate; and a projection system to project the patterned radiation beam onto a target portion of the substrate. The support is provided with a transparent layer to protect the pattering device. The apparatus further comprises a transparent layer deformation-determining device to determine a deformation profile of the transparent layer, the deformation profile of the transparent layer expressing a deformation of the transparent layer during a scanning movement of the lithographic apparatus, a compensator device which is configured to control at least one of the projection system, the substrate table and the support in response to the deformation profile of the transparent layer to compensate for the deformation of the transparent layer during the scanning movement of the apparatus.
