We generalize these type of lenses by defining the angular distribution of the focal length as a Fourier series. The Fourier coefficients of the lens are optimized, using Particle Swarm Optimization algorithm, to minimize the beam width and increase its uniformity for a given depth of focus. In order to obtain a fast simulation during the optimization process, we used Chirp Z-transform algorithm. Finally, we performed an experimental verification of the results using a Spatial Light Modulator. The Fourier series diffractive lens presents a more uniform and narrower beam than previous angular lenses, in both simulations and experiments. These results may find applications in the design of contact and intraocular lenses with extended depth of focus, laser focusing and imaging systems. 000126237 536__ $$9info:eu-repo/grantAgreement/ES/MICINN/PID2019-105918GB-I00$$9info:eu-repo/grantAgreement/ES/MICINN/PID2021-122486OA-I00$$9info:eu-repo/grantAgreement/ES/MICINN/RTC-2019-007113-3 000126237 540__ $$9info:eu-repo/semantics/openAccess$$aby-nc-nd$$uhttp://creativecommons.org/licenses/by-nc-nd/3.0/es/ 000126237 590__ $$a4.6$$b2023 000126237 592__ $$a0.878$$b2023 000126237 591__ $$aOPTICS$$b21 / 119 = 0.176$$c2023$$dQ1$$eT1 000126237 593__ $$aAtomic and Molecular Physics, and Optics$$c2023$$dQ1 000126237 591__ $$aPHYSICS, APPLIED$$b45 / 179 = 0.251$$c2023$$dQ2$$eT1 000126237 593__ $$aElectronic, Optical and Magnetic Materials$$c2023$$dQ1 000126237 593__ $$aElectrical and Electronic Engineering$$c2023$$dQ1 000126237 594__ $$a8.5$$b2023 000126237 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/publishedVersion 000126237 700__ $$aSanchez-Brea, Luis Miguel 000126237 700__ $$adel Hoyo, Jesus 000126237 700__ $$0(orcid)0000-0003-3178-5253$$aTorcal-Milla, Francisco Jose$$uUniversidad de Zaragoza 000126237 700__ $$aGomez-Pedrero, Jose Antonio 000126237 7102_ $$12002$$2385$$aUniversidad de Zaragoza$$bDpto.
