应用初级球差理论分析惠更斯目镜的结构

The analysis of the structure of Huygens′ eyepiece by applying primary sphericalaberrations theory

光学仪器要求系统成像尽可能地消除球面像差和色差.应用薄透镜初级球差的理论,从数学上分析证明惠更斯目镜中场镜与视镜取平凸透镜为最佳形状,使系统成像的球面像差为最小.

Optical instruments require system imaging to eliminate spherical aberration in so far as possible. Mathe matical analysis based on the theory of the primary spherical aberration of a thin lens proves that the field lens and ocular lens of Huygens＇ eyepiece take the plane convex lens as the optimum shape, and as a result, the spherical aberration of system imaging is the minimum.
