The Eye and Visual Optical Instruments
35.2 Irregular monochromatic aberration If one measures the spherical
aberration of the eye in different azimuths, it is soon apparent that the aberration
is not rotationally symmetric. The presence of asymmetries in spherical
aberration has led ...

These comprise spherical aberration, chromatic aberration, and astigmatism. 6.5.
A Spherical Aberration The term 'spherical aberration' has almost entered the
popular vocabulary since its presence was discerned in the main optics of the ...

Aberration Theory Made Simple
For p = -1, the values of q giving minimum spherical aberration (q = 0.71) and
zero coma (q = 0.8) are approximately equal to each other. Thus, a lens designed
for zero coma for parallel incident light will have practically the minimum amount
...

In particular, the Strehl ratios for balanced spherical aberration or balanced
astigmatism are significantly smaller than the corresponding values without
balancing. For a uniform pupil, however, the Strehl ratio for a given value of σw is
the same ...

Fundamental Optical Design
total spherical aberration will depend on the refractive index. If the refractive
index is low, the minimum spherical aberration is not greatly affected by the fact
that the second lens operates in a converging beam, and the spherical aberration
is ...

Mastering Refractive IOLs: The Art and Science
Regarding customization of the aspheric correction, it has been suggested that
achieving zero total spherical aberration postoperatively provides the best quality
of vision. Piers and coauthors utilized an adaptive optics simulator to assess ...
For example, for a convex lens, the marginal rays (which are incident near the
Lateral spherical aberration Longitudinal spherical aberration periphery of the
lens) focus at a point closer than the focal point of paraxial rays [see Fig. 6.4(a)].

Monochromatic Aberrations Spherical Aberration This axial aberration is
generated by non-spherical wavefronts produced by the objective itself or by
improper use of the objective, FIGURES 7.3 and 7.4. Horizontal (focal plane) and
vertical ...

Optical Imaging and Aberrations: Ray geometrical optics
It was shown in Section 6.4 that a spherical mirror with an aperture stop located
at its center of curvature gives only spherical aberration and field curvature. The
Schmidt plate compensates for the spherical aberration and, therefore, the image
...

Competition Science Vision
The rays nearer to principal axis are called paraxial rays and the rays far from the
principal axis are called marginal rays. Focal length of a lens is minimum for
marginal rays and maximum for paraxial rays. Spherical Aberration When light
rays ...
