Diagram of Axicon and resulting Bessel Beam

An axicon is a specialized type of lens which has a conical surface. An axicon images a point source into a line along the optic axis, or transforms a laser beam into a ring.[1] It can be used to turn a Gaussian beam into an approximation to a Bessel beam, with greatly reduced diffraction.[2][3]
