The 14 pages that link to Optical aberration, each with the reason it gives.

• Gravitational lensingCompared with: Instrumental aberrations can mimic distortions, but arise in the telescope rather than along cosmic paths.

• Visual acuityRelated: Aberrations in the eye can blur detail before retinal processing begins.

• Point spread functionRelated: Aberrations change the PSF’s shape and can make it asymmetric.

• Diffraction limitCompared with: Aberrations degrade resolution but are distinct from the limit imposed by diffraction.

• Geometrical opticsRelated: Ray tracing reveals how different rays fail to meet at a single ideal image point.

• LensRelated: Real lenses distort or blur images when rays depart from ideal paths.

• Airy diskCompared with: Aberrations distort the ideal Airy disk and can dominate its diffraction blur.

• Convex lensRelated: A simple convex lens does not bring every wavelength and off-axis ray to the same focus.

• EyepieceNarrower topic: Eyepiece lenses can introduce or correct image defects such as distortion and astigmatism.

• Primary mirrorNarrower topic: Primary-mirror shape errors appear as optical aberrations in telescope images.

• KeratoconusRelated: Irregular corneal shape introduces aberrations beyond ordinary defocus and astigmatism.

• Ritchey–Chrétien telescopeNarrower topic: The design selectively corrects aberrations rather than eliminating every image defect.

• Diffraction-limited systemCompared with: Aberrations broaden images beyond the diffraction pattern and can become the actual resolution limit.

• Focus (optics)Compared with: Aberrations spread rays instead of bringing them to one exact point.
