An information processing system by which it is possible to easily define a lens arrangement and thus make it is possible to easily perform an optical evaluation, wherein a plurality of object positions may be defined for the same focal length of an optical lens system. A lens is designated as the lens used for focusing, and the values to be changed, such as the distances between lenses, are calculated and defined corresponding to the object positions. The arrangement of an optical system may be defined in a plurality of hierarchy levels, and information on decentering may be defined for each decentered configuration of each group including the lens faces.
