Plano Convex Axicons Lens 140DRGEE

Apex  Angle 140 160 170 degree  Plano Convex Axicons Lens (Conical Lens)

Conical axicon lens is conical lenses which are used for variety of applications. When followed by a conventional convex Aspheric 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 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 Lens with a convex conical surface in combination with a convex spherical surface. Such combination focuses laser light into a ring shaped beam with annular focus. Different combinations of focal length and apex angles are available.
