Lens aberrations are imperfections in the way a lens focuses light, leading to distorted or blurred images. These issues can arise from various factors, including the shape of the lens and the materials used in its construction. Common types of aberrations include chromatic aberration, where colors are not focused at the same point, and spherical aberration, which occurs when light rays passing through the edges of a lens focus differently than those passing through the center. These aberrations can affect the quality of images captured by cameras, microscopes, and other optical devices. To minimize these effects, manufacturers often use special lens designs or coatings. Understanding lens aberrations is essential for improving image clarity in photography and other applications involving optics.
