In this article a combination of convergent and divergent Fresnel zone plat in order to increase the focal depth is examined.. It is shown that their combination is a new diffractive element with a novel diffractive properties. Transverse and longitudinal intensity distribution was studied theoretically and experimentally. The effect of the focal length and radius on the intensity distribution was investigated. Experimental works completely verify simulation results.
