Chromatic aberration can be corrected by combining two or more lenses to form a compound lens.

Question

Quizplus · Accepted Answer

Chromatic aberration occurs due to the different wavelengths of light refracting at slightly different angles in a lens, resulting in color fringing. By combining lenses with different dispersion properties, the chromatic aberration can be cancelled out or minimized, resulting in a sharper image. This is known as an achromatic or apochromatic lens system.
