Axicons are optical components with one conical surface that have interesting beam shaping characteristics. When combined with a focusing lens, they generate a circle in their focal plane.
They can be used to create Bessel or non-diffractive beams. They can maintain a small beam size over a longer distance compared to a gaussian beam.
Our axicons feature sub-micron surface quality and high control over its base angle.
