Aberrations in Optics

Aberrations in optics refer to the distortions or imperfections in images produced by lenses or mirrors. They occur when light rays do not converge at a single point after passing through a lens or reflecting off a surface, leading to blurry or warped images. Common types include spherical aberration, where rays at the edges focus differently than those at the center, and chromatic aberration, where different colors of light bend by varying amounts, resulting in color fringes. Understanding these imperfections helps in designing better optical systems, like cameras and telescopes, for clearer images.
