• a first surface and a second surface that are disposed along a direction parallel to the optical axis, and that are spaced apart from each other;
• a first annular surface that is parallel to the optical axis, and that has a first annular edge connected to an outer periphery of said second surface, and a second annular edge spaced apart from said first annular edge;
