Description

Can be made from most optical materials Two axicons together produce a thick-walled hollow "pipe" of light. An axicon followed by a spherical lens produces an annular focus. The axicons can be used to convert a parallel laser beam into a thick-walled hollow "pipe" of light or to produce an annular focus.
