Origin

[edit]

As far as can be ascertained primarily defined by McLoed's paper in 1954: http://www.opticsinfobase.org/josa/abstract.cfm?uri=josa-44-8-592

What are these used for? Are there any industrial uses? Are they primarily used in labs? If so, for what types of experiments? zipz0p 00:47, 11 August 2007 (UTC)Reply

Axicons are mostly used to convert a parallel laser beam into a ring; scientifically, this can be used to trap an atom in an 'optical trap', or to generate plasma in a linear-accelerator (it's a coupling problem; how do you get a laser beam, and an electron beam to have the same path? Electron beams cannot pass through mirrors.) Or for generating Bessel beams, which are free from diffraction.


Industrially, they're used in eye surgery (ring laser spot!), or any other place a ring-shaped spot could be useful.

FYI some people call it axicone. http://www.tydexoptics.com/products/thz_optics/thz_lens/
