The bending of a lens, found useful in reducing spherical aberration, is also useful in reducing coma. The shape factor that needed for minimize coma is close to that for spherical aberration.

Unformatted text preview: So both aberrations may be reduced in the lens by proper geometry. The shape factor for minimize coma aberration equals to: The same procedures for designing a lens with minimum coma aberration comparing with the procedure for spherical aberration can be done.
