HOLO/OR Diffractive Diffusers, also known as Beam Homogenizers, are diffractive optical elements (DOE) that transform single mode or multimode laser beams into a defined shape with homogenized distribution. Each diffuser has a specified diffusion angle at their design wavelength which in combination with a lens controls the spot size. HOLO/OR Diffractive Diffusers are available with square or circular shape outputs and are also offered as a high homogeneity version which provides higher homogeneity and lower zero order than standard diffractive diffusers. HOLO/OR Diffractive Diffusers are used as in a variety of laser applications, including beam homogenizing, hot spot reducing, areal treatments, and laser material processing applications.
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:
