Patent ID: 7412297

Claim:
A method for designing and manufacturing a lens module, the method comprising: selecting design parameters from a design database having a plurality of design parameters in accordance with characteristics of a lens module desired to be designed, designing the lens module according to the selected design parameters, and storing the selected design parameters of the lens module in an analysis database; analyzing the lens module according to a predetermined analysis process to 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, and storing the quality problems and the analysis parameters corresponding to the lens module into the analysis database, the predetermined analysis process adopting a tolerance analysis to distribute the design parameters and the manufacture parameters of the lens module and classify optic errors of the lens module into a symmetric part and an asymmetric part; and re-designing 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 method.
