Minimum spherical aberration

Minimum spherical aberration refers to a phenomenon in optical systems, such as lenses or mirrors, where light rays do not converge at a single point after passing through a spherical surface. This leads to a blurry image. To achieve minimum spherical aberration, the design and curvature of the lens or mirror are optimized so that different light rays focus at the same point, producing clearer images. This concept is important in various applications, including photography, astronomy, and vision correction, as it enhances image quality by reducing distortion and improving focus.
