    摘要: In some embodiments, a projection objective for lithography includes an optical arrangement of optical elements between an object plane and an image plane. The arrangement generally has at least one intermediate image plane, the arrangement further having at least two correction elements for correcting aberrations, of which a first correction element is arranged optically at least in the vicinity of a pupil plane and a second correction element is arranged in a region which is not optically near either a pupil plane or a field plane.

    摘要: A purely refractive projection objective suitable for immersion microlithography is designed as a single-waist system with five lens groups, in the case of which a first lens group with negative refractive power, a second lens group with positive refractive power, a third lens group with negative refractive power, a fourth lens group with positive refractive power and a fifth lens group with positive refractive power are provided. A constriction site of narrowest constriction of the beam bundle lies in the region of the waist. A waist distance AT exists between the object plane and the constriction site X. The condition AT/L≦0.4 holds for a distance ratio AT/L between the waist distance AT and an object-image distance L of the projection objective. Embodiments of inventive projection objectives reach very high numerical apertures NA>1.1 in conjunction with a large image field and are distinguished by a compact overall size and good correction of the lateral chromatic aberration.
