本文从提高光学系统经济效益的宗旨出发,提出了以成本最小为目标函数,以对比传递函数允许改变量和加工能力为约束条件,用概率统计方法制订光学公差的思想和计算公式,并用实例证明了它的可行性。

This paper tries to analyze the economic beneiits of an optical system, and to make a proposal in the estimating and calculating formulae for making optical tolerance with probability-statistical method. In the equations which are usec to find the solution of tolerance, the target function is minimum cost, while the restraint conditions are the permitted variation of MTF value and manufacturing ability. Its feasibility is proved by a practical example.
