Diffractive Beam Shaper

The uniform spot enables equal treatment to a surface excluding over under exposure of specific areas.

Diffractive beam shaper.

Conventional diffractive beam shaper requires accurate alignment and beam control. Holo or diffractive beam shapers are diffractive optical elements doe that transform laser beams with a nearly gaussian profile into a defined 2d shape with uniform intensity distribution at the focal point of a lens. Beam shaper is a diffractive optical element that modifies the intensity distribution of the beam. Through in phase manipulation of the input beam you can achieve virtually limitless and most importantly speckle free intensity profiles in the output beam.

They also allow you to realize uniform performance for a specific range at a defined distance from the light source. A top hat beam shape r also known as flat top beam shaper is the high end option applicable for laser systems that use single mode low m 2 laser beams typically m 2 1 5. Diffractive diffusers are therefore ideal for laser applications in which a specific laser beam shape is required similarly to refractive homogenizers. These diffractive beam shapers are available in two types top hat or stable top hat.

For example a flat top beam shaper creates a far field profile with a uniform intensity in its center. The diffractive beam shaper is a diffractive optical element doe used to transform an incident laser beam into a uniform intensity spot with a well defined size and shape and with sharp edges on a specific work plane. A diffractive beam shaper allows you to modify the intensity and phase profiles of spatially coherent lasers.
