Axicons Lenses

Conical lenses (axicons) with one conical and one plano surface, defined by their cone apex angle, available in precision and standard grades made of BK7 or UVFS with apex angles from 140° to 179°. Axicons transform light into a ring or create an approximation of a non-diffractive Bessel beam from a collimated Gaussian beam; combined with spherical lenses they can produce a hollow light pipe or an annular focus. Uncoated and AR coated versions are available.
