An imaging apparatus where images of good quality can be obtained without being affected by the diffraction phenomenon and without recourse to any polishing. The imaging apparatus is adapted to form a subject image on an imaging plane having light receptor elements arranged on it via an imaging optical system. The imaging optical system has a molded optical element fabricated through a fabrication process in which a periodic streak is produced on an optical surface. When a high-brightness subject light whose brightness value exceeds the saturation sensitivity of each light receptor element enters the imaging optical system, a nonessential light image resulting from the streak on the optical surface based on the high-brightness subject light is formed on the imaging plane and in an area of a subject image from the high-brightness subject light at the time when the optical plane is supposed to be free of the streak. |
