Description: The shape factor of a meniscus lens is chosen to minimize third-order spherical aberration. A meniscus lens would be appropriate for fast systems (f/5 or faster), where the spherical aberration introduced can be much greater than the diffraction effects. In this case, the shape of the lens should

Family of Flat Field Meniscus Corrector Catadioptric Lenses Of The Maksutov Type
The under -corrected spherical aberration of the primary mirror is essentially balanced out by the over- corrected spherical aberration contributed by the weak meniscus lens .
Reflecting Telescope Optics I
The front meniscus lens of Fig. 4.15 is about the same size as the same au- thors’ design for the 3.9 m AAT, i.e. the size relative to the primary (g−value above) is much larger in the latter case.
Design Examples Of Hybrid Refractive-Diffractive Lenses
The Mangin mirror consists of a spherical mirror in contact with a thin meniscus lens which corrects the spherical aberration introduced by the mirror but, introduces chromatic aberrations if the meniscus lens is not achromatized.
