An axicon is a specialized type of lens which has a conical surface. It is used to transform a Gaussian beam into a Bessel beam. An axicon focuses radiation into a line consisting of a set of points along the optical axis. The line forms an equal-width ring with diameter increasing with the distance from the optical element.
Our axicons are made of HRFZ-Si. They are manufactured only upon request.
