    Abstract: A Method of Calibrating a Lithographic Apparatus, an Alignment Method, a Computer Program, a Lithographic Apparatus and a Device Manufacturing Method A method of compensating for the distortion of front-to-backside alignment optics in which displacement vector between the estimated position of a substrate mark and the actual position of a substrate mark is calculated. An optical correction array is also calculated by moving a reference substrate by a fixed amount and comparing how far an image of a point on the back side of a reference substrate moves to how far a corresponding point on the front side of the substrate moves. The displacement vector and optical correction array are then used to accurately calculate the position of further substrates. The front-to-backside alignment optics may be sufficiently large to simultaneously project a plurality of marks through each branch. A reference mark is implanted in the object window of the front-to-backside alignment optics and a relative change in the position of the images of the reference mark and substrate mark projected through a single branch of the front-to-backside alignment optics can indicate a change in the optical characteristics of the front-to-backside alignment optics.
