Abstract This paper presents the spherically symmetric gradient-index axicon, a new kind of axicon that can be designed, using geometrical optics and conservation of energy in the geometric limit, to produce a variety of different intensity patterns along the axis. The performance of one particular axicon design is analysed using the scalar wave model.
