Spherical lens can converge or diverge the transmission beam and form image of the object, which is widely used in various applications
Lenses are classified by the curvature of the two optical surfaces. A lens is biconvex (or double convex, or just convex) if both surfaces are convex.
If both surfaces have the same radius of curvature, the lens is equiconvex.
