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. These diffractive beam shapers are available in two types, top-hat or stable top-hat. Top-hat beam shapers have a larger transfer region but better defocus behavior compared to stable top-hat beam shapers. HOLO/OR Diffractive Beam Shapers are used in materials processing applications, including laser cutting, scribing, and ablation, as well as illumination applications such as wafer inspection and lithography.
Note: Diffractive optical elements are not intended for use outside of their design wavelength. Diffractive optical elements will have decreased performance if their surfaces become dirty from oil or other substances. It is recommended to always use gloves or finger cots when handling these optics.
Edmund Optics offers a range of diffractive optical elements from HOLO/OR for laser applications, including:
