Biconvex - A lens in which both sides are convex is biconvex. Biconvex lenses are converging lenses. Plano-convex - A lens in which one side is convex and the other is plano. Plano-convex lenses are converging lenses.

$\huge \pink{bi \: concave \: lens}$

Biconcave - A lens in which both sides are concave is biconcave. Biconcave lenses are diverging lenses. Plano-concave - A lens in which one side is concave and the other is plano. Plano-concave lenses are diverging lenses.
