- © 2021 Copernicus. All rights reserved.We devise analytical equations to design a radially symmetric optical system with three stigmatic pairs in the meridional plane. The optical system is composed by an arbitrary number of refractive surfaces. We test the model with ray-tracing techniques and the performance results as expected. The model presented here can be easily generalized for an arbitrary number of stigmatic pairs. © 2021 Society of Photo-Optical Instrumentation Engineers (SPIE).
