Plano-Convex Axicons
Produces a line image along the axis from a point light source or non diffractive Bessel beam
Available diameter up to 50 mm
Plano Convex, Plano Concave and Double Convex available
Various AR coatings are available for all these lenses. Please refer to the Coatings Section

Plano-convex axicons are conical lenses which are used for variety of applications. When followed by a basic spherical lens, axicons can focus laser light to a ring shape with annular focus. This feature can be used in hole drilling, microscopy and medical applications. Another interesting feature of axicons is a possibility to transform Gaussian beam into non-diffractive Bessel beam in the near field. Bessel beams can be used in atom or molecule guiding applications.

Standa offers two types of plano-convex axicons: regular and precision type. Regular axicons will create annularly shaped beam whereas precision axicons will also transform Gaussian beam into a Bessel beam. You can choose accordingly, depending to your specific application.
