摘要
应用 Mathcad7.0按照非球面度均方根值达到极小为准则 ,以实例阐述离轴非球面非球面度及最接近球面半径的求解方法。该方法具有较为普遍的意义 ,适合于任意次、同轴或离轴非球面的最接近球面半径的求解。
With the application of Mathcad 7.0, the asphericity and the best fitting spherical curvature radius of off axis aspherics are resolved according to the minimal criterion for the root mean square of asphericity.The method is suitable for resolving the best fitting spherical curvature radius and asphericity of quadratic,cubic or high order aspherics with the shape of coaxis or off axis.
