Diffractive optical elements (DOEs) are optical components that deflect light into multiple orders at precise angles. Periodicity and their spatial frequencies, rather than the surface topography profile, determine the optical performance. Single-sided & double-sided wafer patterning. Diffractive & refractive optical design & simulation.A Diffractive Beam Splitter splits the incident laser beam into a 1-dimensional or 2-dimensional array of beams. Typically diffractive beam splitters are used in combination with a focusing lens. If so, the output beam array becomes an array of focused spots at a certain distance behind the lens. The arrangement of the spots is not limited to .

diffractive opticsIntroduction. This chapter introduces the fundamentals of diffractive optics, the similarities and differences between diffractive and refractive optics, the advantages of diffractive optics, and current challenges in this field. A quick review of the theoretical formulation of diffraction is presented, along with different theoretical . Diffractive optics have two main advantages. The first is the ability to reduce the size and weight of a camera lens. The diffractive elements in a lens are very thin and light, and work in conjunction with refractive elements to reduce the physical size of the optical path. Second, while a Fresnel lens on its own does not eliminate chromatic .
