A spherical lens has an
aplanatic point (i.e., no spherical aberration) only at a radius that equals the radius of the sphere divided by
Kaynak: Spherical aberrationHans Wolter (1911–1978) was a German physicist who designed an
aplanatic system of grazing incidence mirrors that satisfied the Abbe sine

aplanatic lens and also coined this term. This was a significant step in reducing the aberration in optical systems .

aplanatic lenses.
