When compared with spherical lens, cylindrical lens has smaller spherical aberration and smaller chromatic aberration. Cylindrical lens features unidimensional magnification and could be divided into plano-convex cylindrical lens, plano-concave cylindrical lens, double convex cylindrical lens and double concave cylindrical lens.
