Symmetric-convex Spherical Lenses

Symmetric convex lenses are fabricated with the identical convex surface on both sides of the lens. Due to the symmetry, aberrations such as coma, distortion and chromatic aberration are almost cancelled out. These lenses may be combined with other lenses to form complex imaging systems.
