    • The relationship between the intensity distribution within the exposure field and the attitude and position of a collimator (21) is stored in a collimator position controller (24). The collimator position controller (24) outputs commands to actuators (22) in order to perform position control such that the collimator (21) is positioned with such position and attitude that the intensity within the exposure field becomes uniform. While an apparatus operates and exposure takes place, a light source position sensor (23) constantly measures the position of a light source (12), and the collimator position controller (24) controls the position and attitude of the collimator (21) on the basis of the data of the intensity distribution measured in advance described above, so that the intensity distribution of the exposure light within the exposure field becomes uniform.
    • 曝光区域内的强度分布与准直仪(21)的姿态和位置之间的关系被存储在准直仪位置控制器(24)中。 准直器位置控制器(24)向致动器(22)输出命令,以执行位置控制,使得准直仪(21)以曝光区域内的强度变得均匀的位置和姿态定位。 当设备操作和曝光发生时,光源位置传感器(23)不断测量光源(12)的位置,并且准直仪位置控制器(24)控制准直仪(21)的位置和姿态 基于上述测量的强度分布的数据,使得曝光区域内的曝光光的强度分布变得均匀。
