The design of an axicon-liked cemented doublet-lens system (lens axicon) made of two spherical aberration lenses through controlling and optimizing the spherical aberration of the surface is presented. The lens axicon has the main Bessel beam properties. Compared with axicon,this element is inexpensive and easy to manufacture even with large apertures. The evolution of the generated Bessel beam using lens axicon is simulated by using optical-design software. In the experiment,the Bessel beam patterns are captured in different propagation position. And the experimental results fit well with the theoretical simulation.
