Lenses, those marvels of optical engineering, come in various shapes and sizes, each designed to manipulate light in distinctive ways. Among the diverse lens types, convex and biconvex lenses stand out as essential components in optical systems, from cameras to eyeglasses. In this blog post, let's embark on a journey into the fascinating world of lenses and uncover the key distinctions between convex and biconvex lenses. 1. Defining the Basics: Convex Lens: A convex lens is curved outward, resembling the shape of the outer surface of a sphere. It is thicker at the center than at the edges. Convex lenses are commonly referred to as converging lenses because they converge parallel rays of light towards a focal point. Biconvex Lens: As the name suggests, a biconvex lens has both surfaces curved outward, creating a symmetric convex shape. This lens type is thicker in the center and thinner at the edges on both sides. Like convex lenses, biconvex lenses also converge light towards a ...
