    摘要: The present invention provides a method and system for determining three-dimensional refractive gradient index distribution. The method and system of the present invention determine inhomogeneity data and calculate index of refraction changes in three-dimensions (3D). The method and system provide 3D modeling of an optical object or system that determines the three-dimensional distribution of the refractive index in the object. In one embodiment, the optical object is a blank. In different embodiments, the optical system is more than one blank. In alternative embodiments, the optical system can be a projection optics system that can include optical components such as lenses, filters, plates, and prisms. The present invention also provides a method for selecting a plurality of preferred optical elements to assemble a composite optical system with predetermined parameters.

    摘要: A relay lens is provided in an illumination system for use in microlithography. The relay lens can be used to uniformly illuminate a field at a reticle by telecentric light beams with variable aperture size. The relay lens can include first, second, and third lens groups. At least one of the second and third lens groups can include a single lens. This can reduce costs and increase transmission by requiring less CaF2 because fewer optical elements are used compared to prior systems.
