Abstract:
A mid infrared spectral band continuous zoom system is described herein that can provide a continuous zoom range with a focal length change greater than 25X when thermally imaging a distant object. In addition, a method is described herein for using the mid infrared spectral band continuous zoom system to thermally image the distant object.
Abstract:
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.
