In this paper, an analytic procedure has been developed for the root cause identification of the lens module decentration. By analyzing the lens module according to a predetermined analysis process to generate analysis parameters corresponding to the lens module, and measured performance data can then be compared with these simulated data for validation. This can reveals very valuable information to help fine tune the injection mold.
