Description
Axicon lens a conical lens which, when followed by a conventional lens, can focus laser light to a ring shape.
An axicon will convert a parallel laser beam into a ring. Using axicon together with a spherical lens will produce an annular focus for a hole drilling application. An axicon will create a non diffractive Bessel beam. This feature offered enhanced optical guiding, which was previously limited to the Rayleigh range of the Gaussian beam. High-order Bessel beams offer distinct advantages over other hollow light beams for atom guiding.
