Axilens is a diffractive element that has focusing properties of spherical and conical lens. Spherical lens has high resolution and conical lens has high focal depth. By substituiting apertures of photon sieve into the dark rings of axilens, we have axilens based photon sieve that has more resolution to axilens. In this paper, focusing properties of axilens based photon sieve with two classical and Gaussian distribution of apertures compared together. Axilens based photon sieve with classical distribution just enhanced the resolution power a few. But Gaussian distribution by filtering high space frequencies, in addition to increasing resolution power, enhanced the focal intensity.
