PROBLEM TO BE SOLVED: To make fuzzy focusing hardly generated, and to make a bright image image-formed. SOLUTION: This system is provided with one or plural lens arrays 10, 20 aligned with plural image forming lenses 11, 21 in a row, and an image of an object (m) is image-formed within a prescribed imaging region R by converging light propagated from the object (m) by the plural lenses 11, 21 in the optical system. The plural lenses 11, 21 of the lens arrays 10, 20 are aligned to form plural lines extended to the same direction, and a divergent lens 8 for diverging the received light in a direction crossing with the row direction of the lenses 11, 21 is provided in at least one space selected from the group comprising a space between the lens arrays 10, 20 and the object (m), and a space between the lens arrays 10, 20 and the imaging region R.
