Determination of tolerances is very important during product manufacturing in order to maintain low cost while achieving a consistent level of product performance. However, with optical products, precise, quantitative prediction of tolerance sensitivities, optical performance, and productivity in a mass production environment have been very difficult in the design stage The purpose of this study was the development of a statistical tolerancing system for optical products based on computer simulations (called Virtual PT System). The development of the mass-production simulation system was already reported in the first paper. As the second step of this study; the development of the complex sensitivity analysis system, which is based on the stepwise multiple regression method are reported in this paper. This system analyzes the error data and the MTF data output by mass-production simulation system, and output analysis result of the statistical complex tolerance sensitivity. Furthermore, this paper reports the effect the sensitivity analysis result confirmed by the mass-production simulation.
