Abstract

Tolerancing can be done with three different methods: using differential equations, using exact calculations and using the Monte- Carlo technique. Thanks to the possibilities offered by modern computations, what is called integrated engineering using the Microsoft Windows Component Object Model (COM), it is now possible to use different softwares to make the calculations, collect the results and produce synthetic tables and figures which are quickly and clearly interpretable. This is possible with optical design softwares implementing the Application Programming Interface (API). Lenses for cameraphones are recent examples in which tolerancing is difficult. In order to take right decisions in choosing the tolerances, we have been using the three methods for tolerancing. We are using this example to compare the results obtained.
