    • A mold is prepared in which the use surfaces of the upper and lower molds are the design curved surfaces of an optical lens having a spherical shape. The curved surface shape of the optical lens formed using this mold is measured. The measurement values are approximated to a formula (1) of aspherical surface, and the curved surface of the molded optical lens is specified as an aspherical surface. Information on the error between the specified curved surface of the optical lens and the design curved surface is recorded as correction information in a database for each characteristic of the optical lens. Using the correction information recorded in the database, the design values of the use surfaces of the upper and lower molds for molding the optical lens having an aspherical curved surface are corrected thereby to design an optical lens.
    • 制备模具,其中上模具和下模具的使用表面是具有球形的光学透镜的设计曲面。 测量使用该模具形成的光学透镜的曲面形状。 测量值近似于非球面的公式(1),并且模制的光学透镜的曲面被指定为非球面。 关于光学透镜的指定弯曲表面与设计曲面之间的误差的信息作为校正信息记录在数据库中,用于光学透镜的每个特性。 使用记录在数据库中的校正信息,校正用于模制具有非球面曲面的光学透镜的上模和下模的使用表面的设计值,从而设计光学透镜。
