The variation of the coma and the zonal spherical aberration with the refractive indices and dispersions of the glasses of an achromatic cemented doublet Mangin mirror corrected for spherical aberration is discussed. Approximate expressions for the former two aberrations in terms of the glass constants are given, and it is shown how these expressions may be used for the selection of a glass combination which effects simultaneous correction of these aberrations as far as is possible with the available optical glasses.
讨论了消色差胶合双合曼金镜在消除球差时，彗差和区域球差随玻璃折射率和色散的变化。给出了用玻璃常数表示前两种像差的近似表达式，并说明了如何利用这些表达式来选择玻璃组合，以便尽可能地利用现有的光学玻璃同时校正这些像差。
