Abstract
An illumination optical system is configured to convert an intensity distribution of incident light in a long axis direction from a Gaussian distribution, to thereby bring an intensity distribution of a shaped beam on a modulation surface of an optical modulator in the long axis direction into a top hat distribution, and to guide the incident light to the optical modulator as parallel light in the long axis direction and as convergent light in the short axis direction. A short axis side light shielding part is disposed at a condensing position on a short axis side of a modulated beam which is emitted from the optical modulator and is convergent light on a short axis side and blocks a non-zero-order diffracted beam on the short axis side of the modulated beam.
