AI Overview

Cone lenses, often known as axicons, are specialized optical elements with a conical surface used to transform laser beams into ring-shaped profiles, Bessel beams, or 360-degree radial illumination. They are essential for precision laser processing, medical devices, imaging systems, and beam shaping, often providing uniform light distribution compared to traditional lenses.

Axicon Lenses: These lenses create non-diffractive Bessel-like beams or turn collimated laser beams into rings. Used in applications such as atomic traps, ophthalmology (eye surgery), and generating plasma.
Rod Lenses (Cone/End-Worked): Cylindrical rod lenses with conical ends are utilized for 360-degree illumination, radial light distribution, and in systems requiring compact, high-efficiency light control like endoscopes.
Laser Beam Shaping: They are used to create annular focus (thick-walled hollow "pipes" of light) when combined with other lenses.
Imaging & Metrology: Ideal for laser alignment, barcode scanning, and high-precision inspection where a uniformly distributed radial or line beam is necessary.

Plano-Convex Axicon: A flat surface with a conical surface for generating rings or Bessel beams.
Double-Convex/Concave Axicon: Used for more complex beam manipulation and non-linear optics.
Fresnel Axicon: A compact, lightweight, and stepped surface design often used in space-constrained applications.
Materials: Frequently constructed from BK7 glass, fused silica (for UV), and ZnSe (for high-power lasers).
