Concavo-convex

Concavo-convex describes a lens or object having a surface that is concave (curved inward) on one side and convex (curved outward) on the other. This unique combination creates a lens with both converging and diverging properties, affecting how light rays are refracted and focused. The term highlights the contrasting curvature of the two surfaces, essential to understanding its optical or structural behavior. The concave surface usually has a shorter radius of curvature than the convex surface. This asymmetry differentiates it from a plano-convex or plano-concave lens that has a flat surface on one side. Its shape dictates its refractive power, making it useful in various optical instruments and structural components where controlled light manipulation or stress distribution is vital. This configuration allows for various focal lengths.

Concavo-convex meaning with examples

• The lens in the old spyglass was concavo-convex, allowing it to both gather and focus the incoming light efficiently, creating a magnified image. The curved surfaces, one inward and one outward, bent the light just right. The spyglass's effectiveness depended entirely on the careful shaping of the glass. Without its concavo-convex lens, the details would have been a blur.
• Carefully crafted concavo-convex mirrors in certain telescopes were used to correct for spherical aberration, enhancing the image quality. This intricate shape directed light to the focal point, producing a clearer view of distant celestial bodies. The curvature helped resolve distortions caused by the mirror reflecting surface errors. Its design enabled sharper observations.
• The experimental design of the new building incorporated concavo-convex glass panels in the facade, designed to passively control the amount of sunlight entering the interior. This design feature helps regulate the temperature and minimize glare. The unique shape allowed for a more energy-efficient building design, offering both aesthetics and practicality.
• The sculptor used a specialized technique to shape the glass into concavo-convex forms, creating an artwork with a dynamic interaction with light. The interplay of shadows and highlights transformed the form into an element. Its varied curves gave the piece visual depth. This deliberate manipulation produced dramatic lighting effects.
• The engineering team analyzed the stresses on a concavo-convex structural component for a bridge design, making sure it can withstand heavy loads and environmental factors. The unusual curved geometry allowed for optimal support. The load distribution depended on its unique shape. They were considering the tension the convex side puts on the concave side.
