Axicon lens also known as conical lens and piano convex axicons. It can be used to convert a parallel laser beam into a ring, to create a non diffractive Bessel beam or to focus a parallel beam into long focus depth. It is with the characteristics of small dark spot size, spin and orbital angular momentum, and transmission invariance, which make them widely used in modern physics, biology, medicine, optical communication, optical sensing, optical constraints and other fields. The conical lens method is the most convenient and effective way to produce hollow beams. Especially, the collimated hollow beams with good quality can be obtained by using the combination of two optical axis overlapping and the inner and outer conical lenses with the same angle between the conical surface and the bottom of the cone.
