Question

For a single lens, spherical aberration can be minimized by

• A. straightening the lens.
• B. bending the lens into its best form
• C. neglecting small corrections
• D. None of these

Answer 1

The correct option is B bending the lens into its best form

For lenses made with spherical surfaces, rays which are parallel to the optic axis but at different distances from the optic axis fail to converge to the same point. For a single lens, spherical aberration can be minimized by bending the lens into its best form
