| description | The invention relates to an inspection device for masks for semiconductor lithography, comprising an imaging device for imaging a mask, and an image recording device, wherein one or more correction bodies which exhibit a dispersive behavior for at least one subrange of the illumination radiation used for the imaging are arranged in the light path between the mask and the image recording device. The invention furthermore relates to a method for taking account of longitudinal chromatic aberrations in inspection devices for masks, comprising the following steps: recording a specific number of images having differently defocused positions, and selecting a subset of the images and simulating a longitudinal chromatic aberration of a projection exposure apparatus. |
