Abstract
In a process for the correction of non-rotationally-symmetrical image errors in an assembly, e.g., an objective with optical elements, particularly lenses, several Peltier elements are arranged on at least one of the optical elements, distributed over its periphery, and are differently driven electrically in order to act on the temperature distribution in the optical element. A respective temperature-conducting connection is provided between the Peltier elements and the optical element. The invention also relates to an objective with optical elements, particularly lenses, and Peltier elements.
