    摘要: Partial objective for illumination of an image field in an illuminating device of a microlithographic projection exposure apparatus, arranged between a aperture plane and an image plane. The partial objective comprises a first lens group and a second lens group with a lens with a first aspheric lens surface. The second lens group has at least a first lens with negative refractive power and at least a second lens with positive refractive power. The maximum field height Yimmax within the image field is at least 40 mm; the image-side numerical aperture is at least 0.15. The distribution of the chief ray angles PF over the field heights Yim within the image field is given by a pupil function PF(Yim), which consists of a linear contribution c1·Yim and a non-linear contribution PFNL(Yim), the non-linear contribution PFNL(Yim) being at least +15 mrad for the maximum positive field height Yimmax.

    摘要: A projection objective includes a first lens group (G1) of positive refractive power, a second lens group (G2) of negative refractive power and at least one further lens group of positive refractive power in which a diaphragm is mounted. The first lens group (G1) includes exclusively lenses of positive refractive power. The number of lenses of positive refractive power (L101 to L103; L201, L202) of the first lens group (G1) is less than the number of lenses of positive refractive power (L116 to L119; L215 to L217) which are mounted forward of the diaphragm of the further lens group (G5).

    摘要: A projection exposure system is proposed which is positionable between a first object and a second object for imaging the first object in a region of the second object with light of a wavelength band having a width &dgr;&lgr; about a central working wavelength &lgr;, wherein a relative width &dgr;&lgr;/&lgr; of the wavelength band is larger than 0.002, in particular, larger than 0.005, for example, of the Hg-I-line. The projection exposure system is a so-called three-bulge system comprising three bulges having, as a whole, a positive refractive power and two waists having, as a whole, a negative refractive power. By applying suitable measures, in particular, by suitably selecting the material for the lenses forming the projection exposure system, the long-term stability of the system is increased.
