Abstract: <P>PROBLEM TO BE SOLVED: To provide a plastic optical element which is applicable to a high-precision lens used for an optical scanning device with a small beam spot diameter and stably satisfies the requirements of a high-precision optics without a deterioration in optical characteristics due to a change with time in a refractive index distribution.  <P>SOLUTION: The method for manufacturing the plastic optical element comprises the following procedures described below. First, molding conditions favorably influencing the stable formation of the surface shape of the plastic optical element as a molded object, are set with the help of a molding tool, and after releasing the molded object from the molding tool, cooling conditions for achieving the cooling of the molded object at a prescribed rate within a prescribed temperature range, are established. Next, the refractive index distribution of the molded object is measured and a shape error is calculated so as to offset an imaging position deviation based on the measurements. Further, the surface shape of the molding tool is correctively worked so as to reduce the shape error. Finally, the molding operation is carried out under the molding conditions set in the first process using the molding tool whose surface shape is correctively worked and the molded object is obtained under the cooling conditions set in the second process after releasing the molded object.  <P>COPYRIGHT: (C)2004,JPO&NCIPI
