The diffractive beam shaper is a diffractive optical element (DOE) . The diffractive beam shaper is used to transform an incident laser beam into a uniform-intensity spot. The target spot has a well defined size and shape , with sharp edges on a specific work plane. The uniform spot enables equal treatment to a surface, excluding over/under-exposure of specific areas. In addition, the spot from diffractive beam shaper has a sharp transition region that creates a clear border.

A typical DOE is a flat, thin and lightweight element that perfectly fits into compact optical systems.
