Tolerance is a very important parameter for all products to keep stable the product performance with low manufacturing cost. However in optical products, it is very difficult to predict the productivity , optical performance and complex sensitivity of tolerance for mass-production. To solve the above problems and to increase efficiency of manufacturing time and to reduce cost, This study develops the statistical tolerancing system and enables the quantitative analysis of optical performance with productivity before manufacturing. In this paper, we propose a concept of Virtual PT System (PT : Production Try) for optical products such as SLR Lenses. And we report a development of the mass product simulation system based on Monte-Carlo methods according to the proposed concept. Furthermore, we report reliability results based on simulations.
