ABSTRACT:
To obtain an optical element capable of obtaining uniform anti reflection characteristics over the whole optical surface having a finite curvature of the optical element, a plurality of convex optical pieces having an anti reflection function are provided on a surface having the finite curvature of the optical element independently along a normal direction of the surface having the finite curvature of the optical element.
