Plano-convex axicons are conical lenses which are used for variety of applications. When followed by a conventional 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. Plano-Convex Axicons Lens are conical lenses which are used for variety of applications. When followed by a conventional spherical lens, axicons can focus laser light to a ring shape with annular focus. Conical axicon lens feature can be used in hole drilling, microscopy and medical applications. Another interesting feature of convex Aspheric Lens 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.
Plano-convex conical lens has a plano surface in combination with a concave conical surface. Concave axicon produces a ring shaped image along the axis from a point light source (e.g. Gaussian laser beam). Due to specifics in fabrication process, a hole in the center of concave surface is needed. Diameter of the hole is typically 1 mm. Different coatings can be applied on the polished surfaces of axicons. When coated with HR coating, concave conical surface can be used as a conical mirror in some specific applications.
Double convex axicons are available in variety of dimensions and apex angles. Double convex axicons are optical components with a convex conical surface in combination with a convex spherical surface. Such optical glass lens combination focuses laser light into a ring shaped beam with annular focus. Different combinations of focal length and apex angles are available.
