PURPOSE:To form respective optical images obtained by resolving an optical image of an object formed through a photographing lens into at least two or more optical images having different wavelength areas on the same plane at unmagnification in the same direction by arranging fine lenses two-dimensionally in the optical paths. CONSTITUTION:The 1st optical image based upon light transmitted through both two dichroic mirrors Dr, Db are formed on the 1st image forming face. Optical images formed by reflecting the reflected light from the two dichroic mirrors Dr, Db through a full reflection mirror are formed on the 2nd and 3rd image forming faces I'r, I'b as the 2nd and 3rd optical images to be erected optical images with equal magnification by a lens array obtained by arraying fine lenses SLAr, SLAb two-dimensionally. The 1st-3rd image forming faces are adjacently arranged line a straight line on the same plane. Consequently, respective optical images can be formed on respective image forming faces on the same plane at unmagnification in the same direction.
