| Abstract: | A novel optical element, axilens, proposed by Davidson et al., for achieving extended focal length is introduced. We propose a method to design the binary axilens which has high diffraction efficiency. Using computer numerical simulation, we designed 4 axilenses each has different parameters. In this paper we present our results and make comparison with that in ref. 1]. The properties of binary axilens such as the focal depth, the lateral resolution and the intensity distribution along axis is discussed. |
