    摘要: An illumination optical system having a more simplified structure forms various quadrupole-shaped secondary light sources with two-time rotational symmetry with respect to an optical axis. The apparatus can provide illumination conditions that differ in two perpendicular directions on a radiation-receiving plane. In order to form a secondary light source with a quadrupole-shaped light intensity distribution on an illumination pupil plane, a diffractive optical device is provided in which an entrance light beam is converted into four light beams, and a light beam having a shape of four points centered about the optical axis is formed in a far field. The diffractive optical device is provided with a first diffractive optical member that is rotatable about a first axis parallel to the optical axis, and a second diffractive optical member that is rotatable about a second axis parallel to the optical axis, and that is arranged adjacent to the first diffractive optical member. A refractive optical device having first and second refractive optical members accomplishes similar results.
