    Abstract: A reticle (18) for use in a microlithographic projection exposure apparatus, comprises a reticle body (42) containing a pattern (16) and reticle coupling means (36), by means of which the reticle body (42) can be detachably coupled with a reticle-chuck (30). The reticle coupling means (36) are adapted such that the coupling of the reticle (18) with the reticle-chuck (30) can be effected by magnetic forces. Further, a Reticle-chuck (30) is provided which comprises a support unit (60) and chuck coupling means (38), by means of which a reticle (18) can be detachably coupled with the support unit (60). The chuck coupling means (38) are adapted such that the coupling of the reticle (18) with the support unit (60) can be effected by magnetic forces. Furthermore, a reticle positioning system (28) is described, wherein such a reticle (18) and such a reticle-chuck (30) are coupled to form a chuck-unit (32). Finally, an optical system having an illumination device (12) for illuminating an optical reticle (18) containing a pattern (16) and a projection objective (14) for imaging the reticle pattern (16) is provided with such a reticle positioning system (28).
