摘　　要：在光学仪器中，非球面透镜具有一定的实用价值，故对旋转二次曲面透镜光学性质的研究将有重要意义．根据等效光学系统理论和旋转二次曲面折射的焦距公式，并考虑了透镜两曲面的不同形状及不同曲率，导出了旋转二次曲面透镜的主距公式和焦距公式，统称为旋转二次曲面的基点位置公式．这些公式具有一般性，该文进行了分类讨论。Among the optical equipments,non spherical surface lens have been used in some practical ways,the study of optics character of rotational conicoid will be meaningful.According to the theory of equivalent optical system and the formulas of the focal length of rotational conicoid refraction,thought of the different forms and different curvature,the formulas of the principal length and the focal length of rotational conicoid lens are deriued.These formulas have been used widely.They are discussed separately.Practical examples have been given in this article.
