Rafael G. González-Acuña studied industrial physics engineering at the Tecnológico de Monterrey and studied the master’s degree in optomechatronics at the Optics Research Center, A.C. He has PhD from the Tecnológico de Monterrey. His doctoral thesis focuses on the design of free spherical aberration lenses. Rafael has been awarded the 2019 Optical Design and Engineering Scholarship by SPIE and he is the co-author of the IOP book, Analytical lens design. Héctor A. Chaparro-Romo, Economist and Electronic Engineer, he is co-author of the solution to the problem of designing bi-aspheric singlet lenses free of spherical aberration and the adaptative mirror solution. He is the co-author of the IOP book, Analytical lens design and Optical Path Theory.
