PROBLEM TO BE SOLVED: To exactly and efficiently realize the control of a lens forming process step, the shorter and more optimum time for forming and the higher rate of a forming yield. SOLUTION: The method comprises disposing a temperature measuring block capable of embodying the approximation of the temperature in a mold cavity space, attaching a thermocouple sensor thereto, measuring temperature transition and controlling a temperature controller in accordance with the thus obtained data. The exact and efficient control of the lens forming process step can then be performed. COPYRIGHT: (C)2003,JPO |
