Method and system for designing and manufacturing lens modules

A computer-readable medium having computer-executable instructions and installed in a system for designing and manufacturing a lens module, the system comprising a design database, a design module coupled to the design database, an analysis module and an analysis database, the analysis module comprising an error mode effect analysis unit, the design database comprising a plurality of design parameters, the computer-executable instructions, when executed, performing:

• actuating the design module to select from the design database design parameters suitable for the lens module according to characteristics of the lens module, to design the lens module;
• actuating the analysis module to analyze the lens module designed by the design module in accordance with a predetermined analysis process, and generate analysis parameters and manufacturing parameters corresponding to the lens module, so as to show quality problems of the lens module due to manufacturing, light engine interface and assembly, the predetermined analysis process adopting a tolerance analysis to distribute the design parameters and the manufacture parameters of the lens module;
• actuating the error mode effect analysis unit to classify optic errors of the lens module into a symmetric part and an asymmetric part;
• storing the design parameters, the analysis parameters and the quality problems analyzed by the analysis module in the analysis database;
• and
• actuating the design module to further re-design the lens module in accordance with the analysis parameters stored in the analysis database with information obtained after the lens module has been manufactured, so as to adjust precision of the system.
