    • A lighting optical apparatus can be configured to cope with both the suppression of bad influence of image formation due to a field stop and the improvement of an uniform distribution of an exposure amount in the case where the lighting optical apparatus is applied to photolithography equipment that uses a reflection type original sheet, for instance. A lighting optical apparatus is set to light a second surface that is optically conjugate with a first surface through the reflection type original sheet (M) that can be arranged at the first surface. The lighting optical apparatus is provided with a first partial field stop (21) arranged to define a first outer edge of a lighting region to be formed on the second surface in order to limit a light flux incident on the first surface, and a second partial field stop (22) arranged to define a second outer edge of a lighting region in order to limit a light flux reflecting from the reflection type original sheet that can be arranged on the first surface. A first distance (D1) between the first partial field stop and the first surface is set to be larger than a second distance (D2) between the second partial field stop and the first surface.
    • 照明光学装置可以被配置为能够应对由于场停止引起的图像形成的不良影响的抑制以及在将照明光学装置应用于使用的光刻设备的情况下曝光量的均匀分布的改善 例如反射型原稿。 照明光学装置被设置为通过能够布置在第一表面处的反射型原稿(M)来照射与第一表面光学共轭的第二表面。 照明光学装置设置有第一部分场停止器(21),其被布置为限定要形成在第二表面上的点亮区域的第一外边缘,以便限制入射在第一表面上的光通量,以及第二部分场 场阻挡件(22),其布置成限定照明区域的第二外边缘,以便限制从可布置在第一表面上的反射型原稿片反射的光束。 将第一局部场停止与第一表面之间的第一距离(D1)设定为大于第二局部场停止与第一表面之间的第二距离(D2)。
