Like plano-convex lenses, double convex lenses have positive focal lengths and form both real and virtual images. Symmetry is assured by finishing both surfaces with the same tool. Because of symmetry, aberrations including coma, distortion and lateral chromatic aberration almost exactly canceled at unit conjugate radio. Double-convex lenses have shorter focal lengths than plano-convex lenses of equal diameter and surface radius.
