摘要
根据非球面眼镜片的赛德尔 (Seidel)初级像差理论 ,分析讨论了在消像散条件下校正球差、彗差和畸变的可能性 ,指出适当优化镜片的形状因子 ,能够获得畸变低于球面镜片的点焦 (即消像散 )非球面镜片。以± 6 .0m- 1 镜片为例 ,给出了校正畸变、点焦、无拐点非球面镜片的设计方法与结果 ,通过性能评价和比较 。
The conditions are discussed under which the spherical aberration, coma and distortion of point-focal, i.e. free of astigmatism, the spectacle lenses can be corrected on the basis of the Seidel aberrations of the optical system consisting of eye and aspheric spectacle lens. It is shown that distortions of point focal aspheric spectacles lens can be lower than spherical ones through optimizing their form factor and that only the lens with deep back-surface could be corrected both astigmatism and distortion at the same time. An approach for designing distortion-corrected point-focal aspheric spectacle lenses free of inflection points along their aspheric surface is presented. As an example, various of aspheric lenses with ± 6.0 m-1 are obtained. The performance comparison indicates that the aberration correction of aspheric spectacle lens agrees with the predictions of its primary aberration theory.
