Product Description

Product Description:Conical lens, axicon includes plano-convex conical lens, plano-concave conical lens and biconvex conical prism.

Product data:
1) The plano-convex conical lens can focus the laser beam into a laser ring. The conical lens transforms the parallel laser beam into a ring-shaped laser, and is used in conjunction with the spherical mirror to produce an angular focusing effect, which is very suitable for laser drilling. The truncated conical lens produces a non-diffracted Bessel beam, a feature that enhances light guiding performance, while the light guiding of Gaussian beams in the Rayleigh range is limited. Higher-order Bessel beams are far superior to other hollow beams in the field of atomic guidance (atomic optical guidance, atomic laser guidance).

2) Plano-concave conical lens is composed of a plane and a concave conical plane. This plano-concave conical lens converts a spot of light into rays along its axis. Moreover, there is a small hole in the center of the plano-concave conical lens. This small hole is caused by processing needs. The diameter of the small hole is about 1mm.
