【Technical articles】Optical System Tolerancing

2018.07

Introduction
During the design of any optical system destined to be manufactured, it is critical to define a fabrication and assembly budget. This budget must consider any potential compensation that will be used during the manufacturing process to mitigate the performance degradation introduced by fabrication variations. It is important to specify the best set of tolerances and compensators, as these will significantly impact the manufacturing costs. The complex process of defining system tolerances and compensators is often simply called, tolerancing.
Some minimum tolerances are dictated by the manufacturing process. It is important to perform a sensitivity analysis on these tolerances to determine the as-built performance of the system. Alternatively, an acceptable performance degradation may drive the tolerances. An inverse sensitivity analysis determines the set of tolerances that achieve a specific performance degradation. Both of these analyses should consider the effects of permissible compensators.
