- By shifting spherical phase distribution radially, extracted new phase distribution that convert incident plane wave into annular shape. Axilens is a diffractive optical element which has high focal depth and high resolution power. With combination of this tow spherical phase, new phase distribution proposed that produces focused annular in high focal depth: in other hands an optical cylinder. Radius of focused annular depends on amount of phase shifting. Also length of cylinder appointed by focal depth in axilens phase and annular width by focal length. In addition radius of cylinder reduced a few by increasing axial distance from sample.
Keywords: Axilens, Focal depth, Optical cylinder
