Axicon Lens
Axicon lenses use a precision conical surface to transform a collimated input beam into a ring-shaped distribution or a Bessel-like beam with an extended depth of focus.
Axicon Lens Overview
Axicon Lenses feature a conical optical surface rather than the spherical surface used by conventional focusing lenses.
Chenyu Optics manufactures custom axicons from fused silica and optical glass. Diameter, center thickness, apex angle, cone angle, surface quality and coating can be customized.
UV, visible and NIR AR coatings are available for laser beam shaping, Bessel-like beam generation, alignment, processing and scientific systems.
Key Advantages of Axicon Lenses
Laser Beam Shaping & Bessel-Like Beam Generation

Axicon Lens FAQ
What is an axicon lens?
An axicon is an optical element with a conical surface that transforms an incident beam into a ring-shaped distribution or a Bessel-like beam.
What is an axicon lens used for?
Axicons are used for Bessel-like beam generation, ring-beam generation, laser beam shaping, laser processing, optical alignment and scientific research.
What is the difference between an axicon and a conventional focusing lens?
A conventional lens focuses a collimated beam toward a focal point, while an axicon produces an extended axial region and can generate ring-shaped or Bessel-like distributions.
Can the apex angle be customized?
Yes. The apex angle, cone angle, diameter, center thickness and other geometric parameters can be customized for the required beam transformation.
Are AR coatings available for Axicon lenses?
Yes. UV, visible and NIR AR coatings can be customized for the operating wavelength and laser system requirements.
What information should I provide for a quotation?
Please provide the wavelength, material, diameter, center thickness, apex or cone angle, input beam parameters, required output beam, working distance, surface specifications, coating, laser power and quantity.
