Chromatic aberration is an optical phenomenon that occurs when a lens fails to focus all colors of light to the same point. As a result, images produced by the lens may have color fringing or blurring around the edges of objects. Chromatic aberration can be caused by the different wavelengths of light bending at different angles as they pass through the lens, resulting in a blurred or distorted image. Researchers study chromatic aberration in order to develop methods to minimize or correct this optical distortion in various imaging systems, such as cameras, microscopes, and telescopes.
