Determination of tolerances is very important during product manufacturing in order to maintain low cost while achieving a consistent level of product performance. The purpose of this study was the improvement of productivity of optical products like as SLR lens. Therefor this study had proposed the "Virtual PT System" concept as a method to realize the suitable tolerancing for optical products and realized this system. According to this concept, this report proposes the new product model of SLR lens to evaluate the optical performance in real product condition. The proposed SLR lens model can represent uniquely the position and orientation of all parts as relationship of coordinate transformation. And also, this model can represent the mechanical structure with both manufacturing error and assembling error by same manner. Using this SLR lens model, the designer can easily obtain the both lens surfaces decentering amount and optical performance on real product condition precisely.
