The proposed achromatic zone plate consists of two spatially multiplexed zone plates following the geometry given by a chessboard and improved with morphological filters and combination under the Nyquist frequency, to mitigate aliasing effects. The obtained results are compared with those given by a random pixel-based multiplexed zone plate, reported in the literature, showing similar optical behaviour. However, the chessboard-based zone plate presents a smoother appearance without the high-frequency irregularities of the random-based designs that could be more resistant to manufacturing errors. The proposed achromatic zone plate could result of interest in fields such as solar concentration, lithography, imaging systems, visual optics, and so on. 000162591 536__ $$9info:eu-repo/grantAgreement/ES/AEI/PID2022-138071OB-I00$$9info:eu-repo/grantAgreement/ES/MICINN/PID2021-122486OA-I00 000162591 540__ $$9info:eu-repo/semantics/openAccess$$aby$$uhttps://creativecommons.org/licenses/by/4.0/deed.es 000162591 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/publishedVersion 000162591 700__ $$aGómez-Pedrero, José Antonio 000162591 700__ $$0(orcid)0000-0003-3178-5253$$aTorcal-Milla, Francisco José$$uUniversidad de Zaragoza 000162591 700__ $$aSanchez-Brea, Luis Miguel 000162591 7102_ $$12002$$2385$$aUniversidad de Zaragoza$$bDpto.
