Abstract
The practical feature of Fresnel-lens has been traditionally designed to satisfy the phase-difference function for a certain object point which is the result of ultra-high index method. For many cases, the practical blazed surface is used only on one side of the lens. Thus, as shown by our former study, the aberration can be reproduced only for a certain object point and cannot be reproduced even in the vicinity of this certain object point. This means that the one side blazed Fresnel lens has intrinsically aberration whether it is basically designed by high-index method or not. Since DOE or Fresnel lens are applied to many optical lens, we should consider the aberration caused by one side blazed Fresnel lens especially for a precise optics. In this paper, we derive the limit of Fresnel lens as F -number of DOE or Fresnel lens surface.
