Abstract:
1. A system comprising: a pattern generator having a surface that is configured to generate modulated light and associated with a first axis along and orthogonal to a center of the surface; an off-axis mirror segment configured to receive the modulated light, a second axis, associated with the off-axis mirror segment, being spaced a distance from a third axis located along and orthogonal to a center of a surface of a substrate configured to receive an image from a projection system having multiple mirror segments, the off-axis mirror segment being the first minor segment within the projection system; an aperture stop configured to receive the modulated light from the off-axis mirror segment; and a refractive lens group configured to focus the modulated light onto the substrate, wherein the first axis is different from the third.
