Details

Biconvex lenses are used as magnifiers, objectives, condensing systems. Since both surfaces contribute to the power of biconvex lenses, they have shorter focal length than PCX lenses of equal diameter and surface radius.

Converges incident light
Lower spherical aberrations than for Plano-Convex lenses
Ideal for Experimenting and Prototyping Applications
