WebSpherical aberration is dependent upon focal length, aperture, shape and object position. Typically, a simple positive lens suffers from under corrected spherical aberration where off-axis rays focus closer to the lens than the paraxial rays, as shown below. Undercorrected spherical aberration in a positive singlet Web27 mei 2024 · Visually, spherical aberration causes blur, loss of contrast and halos around lights.

Web5 dec. 2011 · Spherical aberration happens when light passing through the edges of the lens elements comes into focus at a slightly different point than light passing through the center. This aberration softens the image. Spherical aberration is normally an issue only with prime lenses used at the widest aperture settings, such as f1.0, f1.2, f1.4, or f1.8.
