摘要
透射凸二次非球面具有自消球差的能力。只要像距、物距、材料的折射率及二次曲面系数之间满足一定的条件 ,则物点与像点就具有消球差的成像关系。研究了二次非球面系数e2 值与成像放大率 β 的关系 ,目的在于为透射凸二次非球面的检验找到普遍适用的范围。实例计算和实际的应用表明 ,对于中小口径的凸非球面来说 ,透射补偿法是比较实用的检验方法 ,特别是此种方法可以检验一些凸的扁球面。
Refractive convex conic aspheric surface has selfaplanatic capability, as long as the object and image distances, refraction index of material and th e conic constant satisfy certain condition, then, object point and image point h ave aplanatic imaging relationship. The relationships between e 2 and β are discussed in details, aiming at finding the generally available range on testing the refractive convex conic surfaces. The example calculation with the m ethod compensating reflection inside the aspheres is compared.
