The effects of the process parameters in the molding of aspheric glass lenses for camera phone modules have been investigated experimentally and the surface topographies of the mold and the molded lens were compared to ascertain the transcription characteristics. The molding conditions were optimized with respect to the form error (PV) (the response variable) of the molded lens. The experimental conditions were obtained by employing a factorial design method. From the analysis of variance (ANOVA) and P-value (significance level), the slow cooling rate was found to affect the response variable most significantly. For the form topography, the lens molded under the optimum molding condition showed a transcription ratio of 93.4% against the mold.
