Acuña-Romo Lens

• Daniel Malacara Hernández presents an approximate design of a spherical aberration-free lens with two aspherical surfaces.

• Psang Dain Lin and Chung-Yu Tsai obtain the spherical aberration-free lens design from the numerical solution of a system of non-linear equations. .

• Juan Camilo Valencia Estrada shows an analytical solution to the problem for certain particular cases

• Rafael G. González-Acuña and Héctor A. Chaparro-Romo present the general closed form equation for the design of a lens free of spherical aberration.

Illustrative examples of Acuña-Romo lenses

Negative refraction index case

The Acuña-Romo equation can be extended to the non-rotationally symmetric case.

Analogy with the parabolic mirror

The Acuña-Romo equations have an analogy with the parabolic mirror and the elliptical mirror since these mirrors are free of spherical aberration and the Acuña-Romo equation describes free lenses of spherical aberration.
