Diffractive Optical Elements (DOE) are manufactured to have microstructure patterns that alter and control the phase of transmitted laser light. By altering the microstructures, it is possible for a diffractive optical element to produce almost any beam intensity profile or beam shape to meet application requirements. These optical elements are manufactured from various substrates, including plastic, fused silica, germanium, sapphire, and zinc selenide (ZnSe), enabling their use with UV, visible, and infrared (IR) lasers. Diffractive Optical Elements are generally designed for a specific laser wavelength and their performance is wavelength dependent.
Edmund Optics offers a variety of Diffractive Optical Elements, including Diffractive Diffusers, Diffractive Beamsplitters, Diffractive Beam Samplers, Diffractive Beam Shapers, Diffractive Axicons, and Diffractive Vortex Phase Plates. These Diffractive Optical Elements are used in a variety of applications, including material processing, medical and aesthetic treatments, and semiconductor wafer inspection.
