The axicon
An axicon is a specialized type of lens which has a conical surface. An axicon transforms a laser beam into a ring shaped distribution. They can be convex or concave and be made of any optical material. The combination with other axicons or lenses allows a wide variety of beam patterns to be generated. It … See more Single axicons are usually used to generate an annular light distribution which is laterally constant along the optical axis over a certain range.
