Diffraction analysis of lens axicons

Axicons, as shown in Fig. 1(a), are optical elements that produce long and narrow focallines along the optical axis, rather than the conventional focal point created by a lens. Thefocal line can be used for e.g. alignment, extending the focal depth of existing methods, orparticle trapping and transportation. Axicons are mainly produced as refractive glass cones,or as di®ractive gratings consisting of concentric circles. They can also be constructed fromordinary lenses or lens systems, referred to as lens axicons. There are several lens axicondesigns, using spherical or aspheric surfaces to produce the necessary amount of sphericalaberration.
