A spatial light modulator has pixel sections for performing spatial light modulation of light. An image-side telecentric image forming optical system forms an image of a two-dimensional pattern of the light having been obtained from the spatial light modulation. A microlens array having microlenses arrayed in two-dimensional directions is located in the vicinity of a plane of image formation of the two-dimensional pattern, whose image is formed by the image forming optical system. A magnification adjusting optical system for adjusting a magnification of image formation at the time of the formation of the image of the two-dimensional pattern of the light with the image forming optical system is located between the image forming optical system and the microlens array.
