摘要:
A telecentricity corrector is incorporated into a microlithographic projection system to achieve telecentricity targets at the output of the microlithographic projection system. The telecentricity corrector is located between an illuminator and a projection lens of the projection system, preferably just in advance of a reticle for controlling angular distributions of light illuminating the reticle.
