A lens axicon (a converging lens with spherical aberration) illuminated by a Gaussian beam is studied. It is demonstrated that, when a backward-type lens axicon is illuminated with an appropriate beam radius of the incident Gaussian beam, one can achieve a focal segment with uniform axial intensity, which is similar to that generated by the logarithmic axicon. It is shown that this approach is very simple and efficient. A forward-type lens axicon illuminated by a Gaussian beam is also investigated.
