摘要：Provided is an optical component including multiple annular zones that eachprovides a predetermined phase to a light flux passing through an optical system, wherefor each of the annular zones, the surface closer to the inner circumference of the optical

component is substantially equal in area to the surface closer to the outer circumferencethereof, and in a cross section in the radial direction of the optical component, thetangent at an outer circumferential end of each annular zone is substantially equal ininclination to the tangent at an inner circumferential end thereof.
