    • The present disclosure relates to a method for the production and/or adjustment of an optical arrangement of a projection illumination system, in which at least one actuator is used to set the position of at least one optical element to be manipulated by moving the optical element incrementally with a specific increment size. The increment size of the movement increments is set as a function of the distance of the optical element from the desired position, with the distance being represented by a distance value. If the distance value is above a first threshold value, a substantially constant increment size is set, while the specific increment size decreases as the distance from the desired position decreases if the distance value is below the first threshold value. Alternatively or additionally, a pre-specified deviation from the specific increment size and/or from a pre-specified increment size change rate results in a warning signal and/or ceasing of the movement.
    • 本公开涉及一种用于生产和/或调整投影照明系统的光学装置的方法,其中至少一个致动器用于通过移动光学元件来设置要操纵的至少一个光学元件的位置 递增地以特定的增量大小。 移动增量的增量大小被设置为光学元件距离期望位置的距离的函数,距离由距离值表示。 如果距离值高于第一阈值,则设定基本上恒定的增量大小,而如果距离值低于第一阈值,则特定增量大小随着与期望位置的距离而减小。 或者或另外,与特定增量尺寸和/或预先规定的增量尺寸变化率的预定偏差导致警告信号和/或停止运动。
