Convex Lens vs. Concave Lens — What's the Difference?

By Tayyaba Rehman — Published on October 10, 2023
A Convex Lens converges light rays that are incident upon its surface, whereas a Concave Lens diverges them, spreading them apart.

Key Differences

The Convex Lens is defined by its outward-curved shape, resulting in its capability to converge or focus light rays that pass through it. Alternatively, a Concave Lens is characterized by its inward-curved shape, causing it to diverge or spread out light rays.

Utilizing a Convex Lens in optical systems, one can observe the gathering of light at a particular focal point, facilitating a magnification effect. In contrast, employing a Concave Lens means the system will disperse light, often used to control light dispersion and reduce image sizes.

While the Convex Lens is famed for gathering light, thus assisting in processes where focused light is imperative, the Concave Lens is the go-to for scenarios where light diffusion is desirable to achieve particular optical outcomes, ensuring that the light rays diverge away from a direct path.

One might find a Convex Lens useful in applications like magnifying glasses and camera lenses due to its converging nature and ability to create real and inverted images. The Concave Lens, owing to its light dispersing ability, finds its applications in peepholes and eyeglasses to correct myopia.

The principle of a Convex Lens enables it to generate images that can be either diminished or magnified, based on the object's position relative to the lens's focal point. Conversely, a Concave Lens consistently produces virtual, erect, and diminished images due to its inherent diverging properties.
