What is another word for spherical aberration?
Pronunciation: [sfˈɛɹɪkə͡l ˌabəɹˈe͡ɪʃən] (IPA) 
Spherical aberration is a term used in optics to describe a situation where an image formed by a lens or a mirror is not sharp due to the varying focal points of different parts of the lens or mirror. Some possible synonyms for the term "spherical aberration" are optical distortion, blur, or aberrant refraction. Other related terms might include wavelength dependencies, chromatic aberration, or defocus. To correct for this aberration, different techniques can be employed, such as using multiple lenses or using a different type of lens with a flatter surface. Understanding and mitigating spherical aberration is crucial in the design and implementation of optical systems, from cameras and telescopes to microscopes and laser systems.
