Overview: An axicon, also known as a rotationally symmetric prism, is a lens
that features one conical surface and one plano surface. When
converting a collimated beam into a ring, the plano side of the
axicon should face the collimated source. When used with a collimated Gaussian beam, Axicon lenses create an
approximation of a Bessel beam. Although the ring diameter
increases and decreases proportionally to the distance between the
axicon and the image, the ring thickness remains the same. Axicons
are ideal for measurement and alignment, research, and medical
applications requiring a ring-shaped laser output.
