Top-Hat Beam Shaping Elements > PRODUCTS

A laser beam with a top-hat uniform intensity distribution is desired in many applications. A top-hat beam is also called a flat-top beam or a super-Gaussian beam. We believe that no one can beat us on the design of diffractive optical elements to convert a Gaussian to a flat-top beam in terms of diffraction efficiency and non-uniformity errors.

Product nomination for diffractive top-hat beam-shaping elements



Our standard top-hat beam shaping elements include Gaussian beam to rectangular flat-top beam and Gaussian beam to circular flat-top beam.
