<p><P>PROBLEM TO BE SOLVED: To provide a method of efficiently manufacturing a plastic optical lens having ideal optical characteristics, without repeating such a trial and error process as in the conventional method. <P>SOLUTION: The method of manufacturing the optical lens includes: measuring the optical characteristics of the optical lens molded on the basis of an optical design value (first process); measuring the initial shape of the scheduled corrected surface of the molded optical lens (second process); acquiring the optical characteristics including the effect of the initial shape by simulation by using a shape including the measured initial shape (third process); acquiring the deviation amount of an optical characteristic value based on factors except for the initial shape of the scheduled corrected surface from a difference between the measured optical characteristics and the optical characteristics acquired in the third process (fourth process); acquiring the optical characteristics corrected by reflecting the acquired deviation amount of the optical characteristic value in an optical design formula (fifth process); and acquiring the corrected shape of a corrected surface corresponding to the corrected optical characteristics acquired in the fifth process (sixth process). A mirror surface piece having the acquired corrected shape is machined and the optical lens is molded. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
