An illumination intensity correction device serves for predefining an illumination intensity over an illumination field of a lithographic projection exposure apparatus. The correction device has a plurality of bar-shaped individual stops arranged alongside one another and having bar axes arranged parallel to one another, which are arranged in a manner lined up alongside one another transversely with respect to the bar axes. The individual stops are displaceable into a predefined intensity correction displacement position at least along their respective bar axis with the aid of a displacement drive individually for the purpose of predefining an intensity correction of an illumination of the illumination field. |
