aman comment on "What do you mean by Spherical aberration in lenses?"The inability of a lens of large aperture to bring all the rays in a white beam to focus at a single point is called a Spherical aberration.
spherical aberration can be minimised by the following methods-
1. by using the stops.
2. by placing the lens so that the total deviation is shared equally by the two surfaces of the lens.
3. by using two Plano convex lenses.
