TEST ONLY - Axicons2

Axicons are optical components with one conical surface that have interesting beam shaping characteristics.  They have been introduced in 1970 to generate a ring-shaped focus point when combined with a focusing lens. 

Another application that emerged in early 2000s is the use of axicon to generate Bessel beam, also called non-diffractive beams, that can maintain a very small beam size over long distance compared to gaussian beam.

Doric Lenses manufacture axicons since 2000 with traditional optical polishing that had some limitations in term of flatness and angle control.  In 2015, we started to manufacture axicons with high accuracy CNC polishing machines, and this increased surface quality to sub-micron precision.
