Abstract:In this research, the optimal grinding condition has been obtained by design of experiment(DOE) for the development of aspheric lens for the 3 Mega Pixel, 2.5x optical zoom camera-phone module. Also, the WC mold was processed by the method of ultra precision grinding under this optimal grinding condition. The influence of DLC coating on form accuracy (PV) and surface roughness(Ra) of the mold was evaluated through measurements after DCL coating using ion plating on the ground mold. Also, aspheric glass lens wa… Show more
