In manufacturing an aspheric lens or mirror, it is often convenient to generate a spherical surface as a starting point. The radius of the sphere should be such that the volume of glass which must be removed to achieve the final aspheric is a minimum. Equations for this best-fit sphere are developed and arranged in a form well suited for computer programming.
在制造非球面透镜或反射镜时，通常方便的做法是以生成一个球面作为起点。该球体的半径应使得为实现最终非球面而必须去除的玻璃体积最小。推导了用于此最佳拟合球体的方程，并将其整理成非常适合计算机编程的形式。
