Units are Millimeters.
Paraxial Focus compensation is on. In this mode, all
compensators are ignored, except paraxial back focus change.
WARNING: RAY AIMING IS OFF. Very loose tolerances may not be computed accurately.
WARNING: Boundary constraints on compensators are ignored when
      using fast mode or user-defined merit functions.

Mode             : Sensitivities
Sampling          : 1
Optimization Cycles : Automatic mode
Nominal Criteria : 0.60319606

請教各位高手指點

这是ZEMAX的报告，你应该指明哪里不清楚，哪里有问题呀！

标题: 請教可行性評估

通過以上公差分析，可行性如何，對加工難易要求如何？

作者: hemet 时间: 2005-5-31 17:02

推荐看一下论坛GGX19458132写的光学镜头的公差分配（1）和（2），不同系统对公差有不同要求的。
