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.
