Abstract
A spatial light modulator performs spatial light modulation of light produced by a light source. An image-side telecentric image forming optical system forms an image of a two-dimensional pattern of the light, which has been obtained from the spatial light modulation, on a photosensitive material. An axial air separation adjusting section is located between the image forming optical system and the photosensitive material. The axial air separation adjusting section alters an axial air separation between the image forming optical system and the photosensitive material and thereby adjusts a focusing point at the time of the formation of the image of the two-dimensional pattern of the light.
