ABSTRACT:
An optical element that can reduce Fresnel (surface) reflection on a lens surface to be a cause of flare or ghost, and a scanning optical system having the same are provided. A microstructure grating is provided on at least one optical surface of the optical element, and the microstructure grating consists of a structure having an antireflection action corresponding to an incidence angle of light beams.
