An Axicon or a Conical Lens is an optical lens with a conical side and flat side, it is defined by its base angles and its apex angle. The working principle of an axicon is that it uses interference to create a focal line along the optical axis. Axicons could be utilized to generate an approximation of a diffraction-free Bessel beam by transforming a collimated Gaussian beam in the near field and converting laser light into an annular shape by taking the projection in the far field. Hangzhou Shalom EO offers Stocked and Custom Axicons (Conical Lenses). The axicons are in plano-convex shape, made of high-quality Fused Silica, and are high-precision polished, featuring superior performance excellent for high-power lasers. The base angles of the axicons range from 0.5°to 40°.
