A Bessel beam is a non-diffractive beam comprised of rings equal in power to one another. Although Bessel beams are only theoretically possible because they require an infinite amount of energy, the output of Plano-Convex (PCX) Axicon Lenses offer a good approximation by maintaining a high level of the non-diffractive Bessel beam properties.
The ring thickness (t) is easily defined by taking ½ of the beam diameter (db):
The diameter of the ring (dr) is defined using the length from lens output to image (L), the index of refraction of the lens material (n), and the angle a:
