This article may be used for non-commercial purposes in accordance with Wiley Terms and Conditions for Self-Archiving."A diffractive optical element having equal-width concentric square rings is analyzed in this article. This constant width makes possible its realization using spatial light modulators or square pixels phase screens. It allows a simple analytical treatment, and the element is also simulated using the Rayleigh-Sommerfeld approach. An experimental verification of its performance has been compared with the simulated results.engDiffractive optical elements with square concentric rings of equal widthjournal articlehttp://dx.doi.org/10.1002/mop.25065http://onlinelibrary.wiley.com/doi/10.1002/mop.25065/abstracthttp://cisne.sim.ucm.es/record=b3528557~S6*spiopen access535.42539.27Diffractive opticsFresnel zone platesSpatial light modulatorÓptica (Física)Óptica física, óptica cuántica2209.19 Óptica Física2209.19 Óptica física
