Convex-concave

Describing a lens or surface that has both convex (curving outward) and concave (curving inward) sections. A convex-concave shape implies a double curvature, often meaning it presents both a bulging and a recessed area when viewed from a specific angle. This term is particularly relevant in optics, describing lenses that correct for both spherical and chromatic aberrations. In general usage, it describes a surface that is a combination of convex and concave, with both a protruding and a recessed area on the same side. Understanding the precise arrangement of the convex and concave portions is key to describing its function.

Convex-concave meaning with examples

• The specialized optical lens featured a convex-concave design to minimize distortion, focusing light with remarkable precision. Scientists were able to make breakthroughs using this design, this feature was instrumental in producing higher-resolution images.
• Sculpting a graceful curve, the artist designed the building with a complex convex-concave facade, creating a stunning interplay of light and shadow, its appeal was both aesthetic and structural.
• The unique lens of the telescope utilized a convex-concave element to correct for chromatic aberration, a phenomenon that could otherwise ruin image quality. This feature greatly enhanced observation capabilities.
• In architectural design, the unique curvature created by the building's convex-concave walls gave it an organic, wave-like appearance. The building was known for its bold expression.
• A highly specialized mirror in the lab was produced with a convex-concave surface to bend light in a manner that created an extremely bright spot for the duration of an experiment.
