Hello,
关于F数求解曲率,在帮助文档的以下路径中有记载哈。
The Setup Tab > Editors Group (Setup Tab) > Lens Data Editor > Solve Types (lens data editor) > Curvature Solves
This solve will force the curvature of the surface such that the marginal ray angle exiting the surface is -1/2F where F is the paraxial F/#. The letter “F” will appear in the cell to indicate that the F/# solve is active on that surface.
个人理解是没有最后一面的曲率半径和最后一面口径/焦距/F数的关系(或者说有隐含的条件没有列出来?)。毕竟到达最后一个表面的边缘光线的方向余弦确定,折射率差确定,似乎没有额外的变量对它产生影响?
