1. the quality or state of being biconvex; the condition of having two convex surfaces
Usage: technical; used in optics and geometry

Examples

• The biconvexity of the lens allows it to focus light effectively.
• The optical properties of the material depend on its biconvexity.
• A biconvex lens exhibits biconvexity on both of its surfaces.
• The biconvexity of the shape makes it useful for magnification applications.
