    摘要: The invention relates to an objective designed as a microlithography projection objective for an operating wavelength. The objective has a greatest adjustable image-side numerical aperture NA, at least one first lens made from a solid transparent body, in particular glass or crystal, with a refractive index nL and at least one liquid lens (F) made from a transparent liquid, with a refractive index nF. At the operating wavelength the first lens has the greatest refractive index nL of all solid lenses of the objective, the refractive index nF of the at least one liquid lens (F) is bigger than the refractive index nL of the first lens and the value of the numerical aperture NA is bigger than 1.

The objective has a greatest adjustable image-side numerical aperture NA, at least one first lens made from a solid transparent body, in particular glass or crystal, with a refractive index nL and at least one liquid lens (F) made from a transparent liquid, with a refractive index NF. At the operating wavelength the first lens has the greatest refractive index nL of all solid lenses of the objective, the refractive index nF of the at least one liquid lens (F) is bigger than the refractive index nL of the first lens and the value of the numerical aperture NA is bigger than 1.

    摘要: A catadioptric projection objective for projecting a pattern arranged in the object plane of the projection objective into the image plane of the projection objective, having: a first objective part for projecting an object field lying in the object plane into a first real intermediate image; a second objective part for generating a second real intermediate image with the radiation coming from the first objective part; a third objective part for generating a third real intermediate image with the radiation coming from the second objective part; and a fourth objective part for projecting the third real intermediate image into the image plane.
