Employing aspherical lenses to reduce aberrations to improve focusing qualities is a well-known concept. But the potpourri of aspherical surfaces offers way more possibilities, even the chance for flexible beam shaping setups. Axicons are conical lenses which create a ring-shaped beam used in research or rather different laser applications. They can be either convex or concave and made from almost any optical material. By combining two or more axicons and lenses multiple intensity profiles can be created.
