ABSTRACT:
This invention relates to an image forming optical apparatus in which a number of micro-lenses are arranged, and images formed by said lenses are superposed to obtain a synthesized image. In the optical apparatus of this kind, individual images have their respective irradiance distribution, and therefore, unevenness in the irradiance distribution of the synthesized image has to be minimized. Where this optical system is used for a copier or the like, exposure is carried out through a slit. The width and position of the slit greatly influence the irradiance for exposure and on unevenness in irradiance. According to the invention, optimum width and position of the slit can be selected to minimize the unevenness in irradiance and provide sufficient exposure.
