    Biconvex lenses are used as magnifiers, objectives, condensing systems in a multi-element system or alone to produce a diverging cone or virtural image. Since both surfaces contribute to the power of biconvex lenses, they have shorter focal length than Plano-convex(PCX) lenses of equal diameter and surface radius. Under customer request anti-reflection or other types of coatings can applied.
