Altechna plano-convex axicons (conical lenses) are used for a variety of applications.
Altechna offers two types of axicons: regular and precision. Regular axicons create an annular beam in a far field, while precision-type axicons also transform a Guassian beam into a non-diffractive Bessel beam in the near field.
The quality of generated ring and Bessel beams as well as all mechanical tolerances are fully evaluated in Altechna's metrology laboratories.
