Abstract
Lens systems designed to work like axicons can be a simple and cheap way of generating focal lines characteristic for these elements. We present two lens axicons made from ordinary lenses with spherical surfaces which take advantage of their inherent spherical aberration for creation of the focal segment. One of them is composed from two lenses with blocked central part. The second one is a single meniscus lens with appropriate reflective coatings. The results show that both new elements exhibit main axicon properties. Additionally the second lens axicon is resistant to astigmatism and maintains good quality of the focal segment even in the case of oblique illumination.
